Roman Korcek: As much as I try I don't see "the hiker wearing a fluorescent yellow jacket" on #10. Would someone please be so kind and paint an arrow or something onto the image for me? Thank you.

They do, but you're right, there is no way one can see that at this resolution.

My god. I really would never have guessed those ~2 pixels to be a hiker. Thanks!

Operator: Wow the Sony A7r II is sooo fast in low light AF - respect!

Hhhhm but wait ...
35mm f/1.4 on the Sony with a bigger distance to the subject
50mm f/1.4 on the Canon and Nikon with a shorter distance to the subject
Wouldn't that not also change the DOF and therefore need a much more precise AF for the DSLRs?

Hhmm yep true but looks like that was not enough to slow down the DSLRs, so lets take a third-party lens to make it even slower. Don't show them the focus performance through the viewfinder of the DSLRs, show them instead a blurry picture - that's much better for our sales figures in our online store.

THX for that "test", you remind me I'm here on a Amazon sales platform, not on a prof. photo site. Forgot that for a second ;-) Anyway I'm happy to see the huge progress mirrorless cameras does in term of AF performance and hope the development continue!

You are forgetting that the profit margin for Amazon is 3 times as high for the D810 than for the A7R2.

In reply to:

ZorSy: They are very nice photographs, executed technically almost to perfection.
BUT.... they represent another artist vision and execution, they are as such not by the pure lack, rather intention and one's creativity. To me, that is always ever-present and somewhat overpowering feeling, the same as photographing nice painting, the sculpture, architectural detail or - God forbid - someone else's photograph.... Therefore, the statement 'Lobbies, office towers and stairwells seem like unlikely places to find artistic inspiration' stands skewed as today they in most cases represent one artist vision (for which they were commissioned in the first place). We (photographers) merely recognise and record it - even artistically, it is still a 'second hand' inspiration.

Well, you could say that about landscapes, portraits, animal and flower photographs, too? Since all of them are already there, looking pretty, you just need to find some composition and lighting?

xiao fei: #1 is one of the nicest photographs I have seen in a long time. The train looks sharp, yet blurred into a single car at the same time. I don't know if this was achieved by overlapping several exposures, or if it's just a long exposure of a long train with identical cars, but, either way, the result is outstanding. Good mix of technically impressive, and artistically beautiful. Very well done Mr. Brewer.

They don't have to be identical cars, the lightest car wins.
EDIT:
Since the EXIF says the exposure time was 5 seconds it was most probably several identical cars as the train wouldn't have traveled the whole distance in that time.

In reply to:

Don Sata: In the list you missed a rotary leg die cast aluminum type table tripod like these:

http://www.bhphotovideo.com/c/product/254830-REG/Delvcam_DELV_DTM_DELV_DTM_Mini_Tripod_for.html

http://www.bhphotovideo.com/c/product/1070031-REG/vanguard_vs_34_tabletop_tripod_metal_with.html

They are super cheap, super resistant and the varying leg angle makes them more useful for tricky surfaces or even for using your own chest as a support.

They don't seem to support the weight the reviewed tripods do (4kg minimum).

Dimit: Uncompressed 14 bit raw ???
No thanks...no need for 100 MB files for something won't even notice in 90% of the cases..

@Barney
I assume the point was having losslessly compressed RAW (as opposed to lossy).

AndyGM: The Mirrorless vs DSLR debate really comes down to viewfinders.

I think we are now at a point where even die hard DSLR fans will say that entry level EVFs are a better experience than entry level OVFs, and even mid range EVFs are a better experience than mid range OVFs.

That just leaves the high end, full frame DSLR OVFs as an example of the best of viewfinder tech.

Someone mentioned they like OVFs because they have full dynamic range. Well I would have thought that was a DISADVANTAGE. The DR of your eyes is over 20 stops, whereas even the best camera are more like 15 stops. So the camera will "see" less than you will, you just don't get a representative idea of the exposure through an OVF.

Plus EVFs can show some much additional information. And an SLR OVF is just dead weight if/when you shoot video.

OVFs (the top end, good ones) have just 2 advantages left AFAICS. No lag. And they are solar powered so save on your batteries!

@Jim
Depends. I prefer to adjust my WB according to the colors I see while shooting. It's much easier for me to do that than try to recall the colors I was seeing while shooting when I finally get to PP.
Also, with some cameras (at least m43) you even get a preview of the motion blur created by a long exposure or you get to see the picture being slowly exposed while doing eg. astrophotography or you see over / underexposed areas marked as such in real time. You can also enlarge the view for critical manual focusing when necessary.

My DSLR-wielding friend once said to me, "You can see how the white balance turns out BEFORE you take the picture?!?"
Seriously, seeing how an image turns out before or during exposure makes so much more sense (at least to me) than to take a picture with the camera to my eye, move it down and away to review the image, adjust camera parameters, rinse, repeat.

In reply to:

Roman Korcek: "whether a camera gives better results by upping the ISO or by keeping the same exposure values, lowering the ISO and boosting the brightness selectively, later"

I am sorry, for the life of me I don't get it. What are the ISO Invariance tests? How do I find out if it's better for a given camera to shoot at ISO 3200 or at ISO 800 and boost +2 EV in PP?

Thanks to anyone who would enlighten me.

The ISO invariance test would then be what I am looking for, thanks!

On Sony SLT-A77 II Review preview (517 comments in total)

Has "Center Lock-on AF" actually been tested?
It is a mode different from and incompatible with the standard "Lock-on AF" that needs to be enabled in the menu (Record menu, page 7) and upon pressing the joystick twice it locks onto whatever is in the center of the frame.

Also, what settings were used for "AF drive speed"? (N.b. that's a different setting from "AF Track Duration".)

In reply to:

Douglas F Watt: It's a shame that Sony inverted their parameter description on AF tracking to mislead almost everyone into believing that a setting of 5 would make for LEAST jumpy, when in fact it is MOST jumpy. So I have to wonder what the DPR would have said about the camera if the reviewers had had early access to Sony's own set of AF parameter recommendations available (but well hidden?) at: http://www.sony.net/Products/di/en-gb/Learnmore/4d_focus/a77/.

I also think that the JPEGs would fare significantly better if high ISO NR is set to low, and at this price point, it is probably the best all-around APS-C body.

Dan,
- What setting did you use for "AF drive speed"? (N.b. that's a different setting than "AF Track Duration".)
- Have you tested "Center Lock-on AF"? It is a mode different from and incompatible with "Lock-on AF" that needs to be enabled in the menu (Record menu, page 7) and upon pressing the joystick twice it locks onto whatever is in the center of the frame.

tom1234567: I don't no why camera makers keep producing cameras with these
SMALL CRAPPY SENSORS

It's time the public were educated to what they are buying
Instead of being ripped off by ALL camera manufactures

So you yes?
