JackM: All I see is a naked emperor.

I understand that, but like I said, if that's what you want there are better choices for a lot less money. Edit - well I suppose I take that back. Indeed any SLR lens on an a7 is going to require a big clunky adapter. If I had an a7 I would prefer a lens with an M-mount flange distance. So in that realm, maybe this is a good value, I don't know.

Pentax SMC (super multi-coated) primes are awesome and can be found in great condition on ebay for around $100. I've modified a 50/1.4 for use on my 5D3. At f/2.8 it's better than my 24-70L.

Haha. Seriously though, IQ looks pretty average and unremarkable. Certainly nothing to make manual focus worth the effort. If MF is the goal, there are many cheaper and better choices.

If you have no idea what you're doing, I suppose.

Skipper494: All very fine, but in film days we got grain from particles in the film, nothing from die film. As an engineer with quite a lot of experience in sensor design, I can assure you that most noise comes from the proximity of photo sites, or wiring, (even poor software) which is why lower resolution large sensors have less noise and more dynamic range.

Compare the Nikon D700 and the Sony NEX 7, for instance. Consider how good the Fuji S2 Pro was in it's day. Compare a lower resolution 1/1.7 sensor with a higher resolution 1/2.33, such as the Nikon P7000 with the Pan FZ35.

Frankly, too much emphasis is put on high numbers and marketing, instead of good photography results.

slag - OK. In general I try not to put much stock in dxo's findings, lest I be led to believe my 5D3 is a bad camera.

Rishi, it would appear from dxomark tests that bigger pixels do = less noise, but not less DR. Look at the "Sports" (noise) score vs the DR score for A7S vs A7R:

Lower noise, yes, more DR no. Compare D750, D810, and Sony A7S on dxomark.

And relatively cheap because it's made by communist slaves.

On Fujifilm XF 16mm F1.4 moves from roadmap to retailers article (228 comments in total)
In reply to:

wootpile: While I applaud the quality of Fuji's lenses, I can't see the benefit of 1.4 in a wideangle. Perhaps someone can explain how a ultra fast wideangle that is heavier, larger and more expensive makes any sense as a photographic tool.

A 2.2 lens would have cost half, been substantially smaller and been easier for Fuji to achieve optical results from...

Seriously? Low light, shallow DOF, bokeh, etc.

You know what's funny is that 20 years ago something this size would be considered normal for a family cam-corder.

On Samsung NX1 Review preview (1237 comments in total)

I bought a 7D2 to reclaim the reach from my 70-200/2.8 that I lost when I went Full Frame. No way I'd go back to using a 50-150.

JackM: The people who click "I own it" or "I had it" really need to grow up.

They should track which users click these buttons and give them demerits. Too many demerits = ban. Maybe even a temp ban on first click.
