Photocameras

Can I get a link to the website of the Donetsk flea market?
It is interesting to compare.

https://www.olx.ua/elektronika/foto-video/t...ch%5Bdist%5D=30

I twisted all sorts of different RAVs with Dpreview to the point of pain in my eyes. It turned out that everything is not so clear (C). Between ISO 200 Nex-F3 and ISO100 Nex-6, the difference in noise is minuscule. How much Nex-5 is worse than F3 is difficult to understand, t, because they were tested with other lenses, but it also seems to be a homeopathic value. But the vaunted Nikon D3100 merged all of the above on all ISO, although the sharpness is better, due to the lens (but there were far from whales everywhere). Similar to the D5100. In turn, the aforementioned Nikons merge Samsung NX210 (NX1100 is not there, but the matrix seems to be the same on it). In general, horror-Kenon 650D and Panasonic G2 (there is no G1, but I think it is not better). Olympus '"Foams" are much better than Panasonic's, and those with a 16-megapixel sensor are almost on par with Nexs. I would probably take one (E-PL5 for example), but such offers are not seen even in Ukraine, not like in Donetsk. I was unexpectedly surprised by the previously criticized Nikon 1J1, in terms of noise on ISO 100 it is almost on a par with the Nexs on ISO200, and it keeps up well at high levels. Much better than G2. But the detail is not enough much, and very sharp lenses that could fix this matter, for this system, as I understand it, no, no at all.

Alas, none of the above images have a perfectly smooth image, even at the minimum ISO, so SHIDEVR is impossible without noise reduction.

The site looked - prices are even higher than in Irkutsk.
Apparently, that's why photos are sold for a long time.
I didn't see any cheap SEL lenses at all.
Strange...
There is no demand, but prices are holding up...
With NEX-F3, in my opinion, 500-700 hryvnias can be traded -
because 10 thousand frames is not such a small mileage,
there is no strap-the question is why they were shot?
It is also necessary to look at the cogs, the m / b case was disassembled for repair,
they sometimes have a control ring-the navipad slips when moving around the menu...
PS
The same seller sells the NEX-5 carcass - so the m/b will also give F3 without a lens.
NEX-5, by the way, looks more ushatannoy in the photo.

What did you want?" We have a blockade on all sides, and Irkutsk is almost close to the producing country. In Ukraine, it is cheaper by a third or more, but you can deliver figs. But even in the old days, I would not have contacted the delivery of fragile electronics by courier services. I know from experience that their employees almost play football with parcels. Once I almost all the eggs of stick insects were killed, despite the fairly strong packaging, the other-the oatmeal came, sawn with substrate particles in half (i.e. the bank was spinning for a long time, like a ball mill).

Strange thing: when I agreed, there was no F3 on the site, the seller offered it to me in a personal account, and for a price of 2 thousand rubles less than it is now in the ad (if you recalculate from hryvnia at the exchange rate). And he didn't say the exact mileage. I'm feeling sick. So, again, I'm left without a mirrorless camera. But I found out that in F3 there is still a front electronic curtain.

If he himself offered 2 tr less, then he will give it back.
One figs no one buys,
nafig him in the blockade a bunch of photos?
He also has to run after such a valuable buyer...

ENO, I want to warn you about olx, there are 0 whole 0 tenths of honest sellers, in the ad he writes one thing but in fact quite another, carefully check the equipment before buying.

Yeah, and I'm one of them, because I sold a lot of things there . And I also bought three cameras there. Probably, it is necessary to make allowances for geography: in Kiev, only buy from godmothers.

And I guessed to check it without your advice.

Well, I'm happy for you. Happy shopping.

KM2200, I'm sorry, but I wonder why you're doing this

Bomka, how did your epic story with Kenan A570 IS end? And then there was the opportunity to take an A4 to replace my A540, in which I am generally satisfied with everything (as for a soap dish), except for the terribly soapy edge of the frame (even panoramas are difficult to sew because of this). The 570th with an edge seems to be significantly better, as well as my old deceased 550th, plus a new processor (like, kamzhpeg improved from this), and an optical stabilizer. But the rate of fire is lower. The bayonet is the same, so all my attachments will fit, unlike, for example, the 6xx series.

how did your epic story with Kenan A570 IS end?

Yes, the A570 is a cool camera.
It was a pity for me to disassemble it, the lens is too cunningly arranged there, you can easily ditch it.
As a result, I gave it together with a macro-nozzle to one of my schoolgirls friends.
But, I still have A710 (already disassembled) lies,
m / b hands will reach another lens to pin it.
Did you
refuse to buy the NEX F3?
It will provide more opportunities for experimentation.

One doesn't interfere with the other. I don't think it's wise to use a mirrorless camera for routine everyday shooting. The shutter is not made of rubber. This is exclusively for Shidevrov and complex technical tasks of a one-time nature. For daily traction in case of the situation "I walk, and it crawls/flies" - a soap dish. I'm just wondering if I should change it to a slightly better one, or if there won't be much of an advantage. After carefully comparing the old photos with the A550 and the newer ones with the A540, I still noticed a significant difference in detail in favor of the former. It is especially significant at the edges and corners of the frame. Bokeh with attachments is also completely different. So, despite the similarity in appearance, focus and aperture ranges, the lenses of these cameras are completely different. Obviously, for the 7-megapixel sensor, the optics are significantly improved. The only question is whether it is not degraded again when adding a stabilizer. Also, I don't like the method of sharpening, which leaves eye-catching halos, which takes place on the A540, and it has been significantly improved on the A550 and subsequent models. Apparently, you need to agree to try it in person. In general, the ideal option would be the A650 IS, even if it would have to make other adapters for it. But for almost three years of monitoring the flea market, not a single working copy of this model has caught my eye.

I haven't decided about F3 yet, because it's still expensive for me. Although at my leisure I looked at offers on Avito in Rostov - Neks are not particularly cheap in the Russian Federation. And with transportation, it will be even more expensive. And Samsung, after watching RAVs with Dpreviewdecretely disliked, as well as Kenons 5xxd-6xxd, which I also looked at earlier, because they are cheaper than mirrorless cameras we have. But still, the hope of a carcass for 50 bucks at least some or for the price of F3, but with EVIE, does not leave me.

If F3 is too expensive, then you can also take NEX 5.
And for a shabby appearance, you can bargain a thousand and a half. :-)

Yes, I didn't notice any special scuffs there. The top five is generally declared with a mileage of 5000, it looks like new. But still with F3 clearly better pictures come out, judging by the Preview, kamzhpeg - so in general the sky and earth. And the price there is actually almost the same, only that he sells the top five separately, and F3-only with kitov 16-55 (or sktolko he is there, I don't remember exactly), and therefore the price is twice as high. Even at the F3, they say, the battery lasts longer, but charging for spare parts is not included in the kit - only in the carcass. The Dxomark rating also impresses, according to which F3 has the best image among Nexes, and 5 has the worst. Although I didn't really notice such a huge difference in colors that they intended there, except that the difference in the number of pixels really affects the detail. I'll probably wait to see which one they buy first and take the rest. Samsung NX1100, by the way, has already left, in just two days.

Today I was forced to try out a new method of shooting on the A540. The batteries ran out in the field, but I forgot the spare houses. As a result, he extended the trunk, focused normally, clicked the shutter and passed out, without taking a picture, of course. And not the captured "models", as for evil, remained full. I figured out that the display was eating up a lot of energy, so I started cutting it down after an approximate focus adjustment, leaving the autofocus entirely at the mercy of the machine. With such a tambourine, we managed to make ten more frames, quite tolerably capturing three types of animals, until complete failure. And before that, I tried everything: I warmed the batteries in my bosom and knocked on the post-one Fig.

Another option appeared: Canon EOS M with a whale lens 18-55mm. at a price a quarter cheaper than the Nexa F3, plus bargaining.

Compared to the specified Nex. Apart from the price, I see the following advantages::

1. The lens, judging by the reviews, is not guano;
2. Phase sensors in the matrix (but here the question is how well they work. fishing for reviews, not really);
3. Available "alternative firmware";
4. Tolerable camera zhpeg, more flexible setting shumordava;
5. There is a connector for connecting the remote control (suddenly, once I decide to make a photoruzho); the remote control, as I understand it, is the usual Kenanovsky DSLR, i.e. available. A deeper dig revealed that the remote is only IR, so I cross it out.
6. Normal hot shoe.
7. Touchscreen, and, allegedly, the best among mirrorless devices (although I'm not particularly sure of its usefulness, because I've never used it on any devices).
8. Magnesium housing;
9. There is an ISO 100!

Disadvantages:
1. The matrix is slightly worse, at the level of the first nexes (according to the Dxomark rating). Careful pixeldroching gave the impression that Kenan's ISO100 is very close to Sonkov's 200 in terms of noise, which negates the last advantage in the list. It is also necessary to take into account that both manufacturers strongly cheat with ISO, so it is not entirely clear what the ratio really is;
2. There is not even a fundamental possibility to connect an external EVI (although I would hardly ever be able to get it in the case of Nex);
3. The display, although larger in resolution, is nailed down. Here-here Kenon seriously made a mistake. After all, byut, it is taken from the D650, i.e. in the original version it was still rotary! Did they really squeeze a minuscule amount of space for the hinge? IMHO, this decision very much undermined the competitiveness of Sony's mirrorless cameras, and clearly did not benefit the company;
4. There is no auto-panorama mode;
5. Quickly eats the battery.
6. There is no normal grip.

Bomka, you, as far as I remember, have a 650D (and the picture from it, they say, is the same as c M), so I'll ask a couple of questions:

1. How big is the real - world difference in image quality with 16-megapixel cameras? For example, do shadows stretch noticeably worse?
2. Is the display really as good as they say it is due to some clever technology: it can be read even in sunny weather from any angle, or are they lying?

1. In real conditions,as for my taste,
pictures from the Canon 650D are not inferior to pictures from the Sony NEX,
and they look even slightly better in terms of resolution of small details
(but this depends on the lens), but slightly worse than pictures from the Sony A6000.
In terms of chroma, IMHO, approximate parity.
Shadows (both here and there) are not very long, or I do not know how to prepare them...
---
2. The 650's display is touch - sensitive, so you can scroll through images, etc.
In the bright sun, it glares like all other displays, especially if it is covered with fingers.
When shooting in the sun, I just turn it around or look through the viewfinder.
In the shadow, yes - the image is clearly visible from different sides.
- - -
3. If "at the price of a quarter cheaper", then you should definitely take it.

Oh, it's too bad that the display goes blind, especially in combination with slowness. The removable EVI only appeared in subsequent models. And a little later - and built-in. In general, Kenon went in mirrorless construction strictly in the footsteps of Sony, stepping on the same rake. But Sony at least immediately thought of the tiltable display.

About the matrix, they agree that it is better in color than sony's, but in terms of noise and, especially, DD-worse. DD is shifted to the area of lights, i.e. in theory it is better to shoot with a positive exposure correction, and then pull out the overexposure. But with drawing out shadows - a bummer. Indeed, when picking RAV, you can see that Kenon has a mess in the shadows (compared to Sony and Nikon). But, in principle, the difference is not catastrophic.

Much more alarming is the low battery capacity combined with great voracity. The owners claim that for normal active shooting, you need to buy more than one spare battery, but three or four at once. This will not be cheaper than Nex, and it will not be operational at all. Although the data is contradictory: someone allegedly managed to squeeze 400 images out of a single charge.and someone - only 80. According to the passport - 200, i.e. more than 2 times less than that of F3.

The music didn't last long: Kenon from the flea market disappeared, and the seller did not answer me. Apparently, they bought it (in just one day!).

One thing I don't understand is why the ideological brothers of the photo expert still haven't chipped in and finally gave him a mirrorless camera Yyy ..

"What you got for nothing is not appreciated."..
Folk wisdom.

Canon 120 Megapixels... Soon.
https://prophotos.ru/news/20226-canon-prode...Fzen.yandex.com

Judging by what they compare with Full HD and say in the video, it will not be a camera, but a kind of super-super-video camera for very specific tasks. Probably, it will be used in movies, science and military service, but it will not be available to ordinary mortals.

Speaking of Kenon: that seller still answered me - he sold a full set of EOS M for 8 thousand rubles, i.e. not even a quarter, as indicated in the ad, but a third cheaper than F3. And half as much as they sell for a similar device in Ukraine. And spare batteries for them, as I installed, you can easily find the original ones for 400 - 500 rubles, or even less. So it's a shame.

The problem is that the Ukrainian mobile operetor recently threw us, who did not have time to get a republican one (like me), can only communicate via the Internet. And sellers respond to mobile phones much faster and more readily than through the communication forum on the flea market website. That is, teliphonized buyers have a head start.

Well, okay, I'll console myself with the fact that Kenon's screen is not rotatable, that for Marco it's really not a fountain.

P.S. A-a-a, someone else is already selling it for 11500 rubles - a speculator bought it!

P. P. S. A570 IS also sold yesterday, exactly at the time when I wrote to the seller. It's like some kind of evil fate.

You can't go against the laws of optics.
Although there are options - for example, use very short-focus lenses. They have a much bigger FLU. However, such makry still look for. I remember that one Japanese enthusiast used surgical endoscopes for such shooting, which he fitted to a video camera. The results are amazing, although there was a noticeable curvature in the field. And the price is "only" $2000-3000

Hm... You will need to try "F-50 A-0.10" for livestock.
The remaining microscopes are more suitable for laboratory photography and stacking.

I screwed today on the Sony A6000
a thin adapter m42-NEX (Slim) +
helicoid m42-m42 (25-55mm) + adapter m42-RMS.
I screwed a microscopic lens "F=50 A=10 plan" backwards into the adapter,
because only in this position can it shoot to infinity.



The weather is overcast... only humans and pigeons were found among the animals.
Results.
1. On the longest possible helicoid
, the distance from the lens to the object was ~ 15 cm.
The coverage width is ~ 4 cm. The shooting scale is ~ 1: 2.

100% crop of a pigeon frame:

2. On a short helikoid, you can shoot to infinity,
there is even a small "run".

100% crop of the temple frame:

Full-size images can be downloaded here:
https://cloud.mail.ru/public/8xEJ/oz3KpHk7S
.
Conclusions:
The "F=50 A=10 plan" lens can be used for
photography as a normal lens, but the image quality
is worse than with the Sony SEL 1855 whale.
On macro b/m, the normal resolution is only in the center,
and at infinity, a strong pillow-like distortion is also added
(it is noticeable on curved pillars and walls of buildings).

In my opinion, this is not our method. What's the point of photographing landscapes with a microscopic lens?

Here are examples of my photos through a 9x0.20 PLAN screwed on Helios-81.
By the way, who can guess whose wing? Well, to the family?

And no vital photos ))
But such a bunch of expensive strays)
A photoexpert generally disappeared somewhere, I hope I bought a megazerkalku, and fotkaet megashedevry instead of sitting on the Forum)

Will be. While the weather is not flying.

But such a bunch of expensive strays)

The helicoid was purchased for 1280 rubles,
a thin adapter for 61 rubles,
and an m42-RMS adapter for 500 rubles.
That is, everything together is cheaper than $30.

And the photoexpert is missing altogether

Donetsk is again being bombed by punishers from Khokhland and NATO.
He doesn't have time for macro photography there, he would have stayed alive.

About your latest photos - what's the point of putting this up?
Scientific value is zero, because they are not signed - where, how and how they were taken.
As it is also, IMHO, not a fountain.
You had some great shots (ktyr, etc.) with a 3.7 x micro lens.
Have you tried to fasten it to the mirrorless camera?

What's the point of photographing landscapes with a microscopic lens?

I agree.
It doesn't make sense.
Kitovy and makrik 30mm will handle this better.
But... I wanted to check it out.

Bomka, after the passages about "punishers from Hohland" - there is no desire to communicate with you. Go through the forest.
