Dylthedog: The 'big box of air' isn't all bad from my understanding. Sure, it might make the camera bigger, but the closer the lens is to the recording plane, the harder it is for optics to keep things sharp across the frame, and deal with distortion.

As a MFT user, which has very little air gap, I'm well aware of the sometimes significant in-camera processing done to fix distortion caused by that small gap and compact lenses, and the fact that diffraction can start as early f5.6. I'm willing to put up with this in my second system as a trade-off for size. I'm not sure I'd want it introduced into my full-frame system though...

If the camera manufacturers did dump the air gap, how much real difference would it make? And could full-frame lenses be made smaller? I doubt by much.

I get the focus system design issues, but I suspect body tech will help to get around that with new lenses phased-in. I doubt sports pros will be reaching for the new mirrorless cameras for a while though.

@DrB Indeed, and I don't have the knowledge to say whether it does make a superior lens. But if it does, then I'd rather accommodate the extra volume once only in my camera bag - within the frame of the camera - rather than multiple times - in each lens.

I am more concerned by weight than by size, and a box of air does not weigh much. If it simplifies the lens design (I'm asking?) and thereby reduces lens weight, then I can happily accommodate the extra air in my camera bag.

great to be reminded that the site is in fact digital PHOTOGRAPHY review, not digital GEAR review (although I'm addicted to the gear stuff as well!).

Funny, on the Sony articles people ask the same question about are they being paid by Sony...

mezastel: I read that the Sony 70-200 GM lens has some focus issues, can anyone comment?

Ok, I believe the text you quote from Lens Rentals refers back to this article:
https://www.lensrentals.com/blog/2017/01/an-update-and-comparison-of-the-sony-fe-70-200mm-f2-8-gm-oss/

Make of it what you will - it seems to be as much a discussion about possible conflict between their test methodology and the Sony lens design as it is about the results obtained.

In any case, they are only referring to focus only in as much as it affects the accuracy of their MTF test - they were not specifically testing focus performance. They were questioning whether poor focus - possibly an artefact of the test methodology - had degraded the MTF results.

hatem95: I am a Sony fan, and I owned 4 previous mirrorless Sony's and I will get the A9 but please stop this media hype. A9 may have super AF, etc.... but the form factor is incompatible with using it as a sports camera in the field. A sports camera needs Sports lenses and these lenses are Huge , I have totally abandoned using my Sony 80-400 with the A7rII not because of AF issues but because it feels very awkward and imbalanced in my hand. if Sony is that clever they should design a small superfast sports lenses to match. otherwise, the A9 is not a sports camera

So, is a 50mm f1.8 lens "unbalanced" on a DSLR?

Dan Vincent: Carey,

Canon and Nikon don't warrant against water intrusion in their bodies, even on the pro ones. The bodies are rugged, yes, but when the rubber hits the road, they won't cover it. I've taken my Sony a99 out into sea spray, rainy weather, and dusty conditions, and when I've had it serviced (for regular reasons like cleaning and adjustments) no one has mentioned anything about contamination.

If you want to believe, take one out yourself and you'll see that while no, you can't dunk it in the lake like a Pentax, it will shrug off the elements.

"Torture tests" makes me think of YouTube folk posting mobile phones subjected to blow torches and other such click-bait ad-generating shenanigans. Amusing, for children below a certain developmental stage.

But I would like to see these cameras robustly tested to the limits implied by their marketing and advertising hype, ignoring any small print disclaimers and weasel warranty waivers. So if they show them taking atmospheric shots of a spume blown lighthouse in a wild atlantic storm, or whatever, go do likewise (check your life insurance first, of course).

FF was a format optimised around the characteristics and limitations of film emulsion and transport, etc and other, earlier legacy baggage. Somehow it has carried on to become the de facto gold standard for digital. This I can understand through the argument of legacy lenses and so on. But when the lens mount changes as it must when going to mirrorless, why do we stick with FF? The very name, "full" frame, gives it a self-appointed status as the complete and correct measure.

Are the measurements 24x36mm by some happy coincidence also optimum for the very different constraints and opportunities of digital sensors, especially the at the current state of maturity?

Yak27: Although Sony website says the viewfinder is Quad VGA, I believe it's actually Quad HD. Because they also say it has 3.6 million dots (3,686,400), which precisely matches Quad HD megapixel count. (The megapixel count of Quad VGA is 1,228,800)

https://en.wikipedia.org/wiki/Graphics_display_resolution#SXGAminus
https://en.wikipedia.org/wiki/WQHD

x3 is for RGB. It's a dots vs pixels thing. Obviously marketing departments quote dots because it yields a bigger number.

You don't have to make any assumptions. You only need to be smart enough to read the viewfinder size listed in the specs.

p5freak: Boring, ancient mirror slap technology from the stone age. The future is mirrorless. Nikon cancels the 18-50 DL, which would have been unique, but releases this dinosaur. USB 2.0 ?? No 4k/60fps ?

@Cameracist

A serious question: do any professional photographers actually use a Leica for work? Honestly, I thought Leica had dwindled into a specialist brand for rich camera aficionados and brand snobs. Could be wrong, I suppose. And Hasselblad? I thought they just stuck plasticised wood-verneer on things. Yes, illustrious history and all that, but today?

Every so often I raise my FE2 to my eye again just to remember what it feels like to have a real "eyeful" of viewfinder.

mailman88: According to Cnet, ZDNet and Digital Trends....both sensors on the S8 will create blurry images in low light.

Was the Phone Arena's shootout also "blind"? Comparison tests where the appraisers know which device shot which picture are not worth squat. Same with wine tasting!

Fun name. I really enjoyed that one.
If only the would drop their bloated android skin, I'd be game..

You seem to be confusing bloat-apps with the TW skin. Two different things. TW has shown stock android the way for many years now, Nougat is just about catching up. The bloat apps - yes, I agree, they should be uninstallable. Personally I like the Samsung browser and dialler and email apps, never found a use for Chat-on etc. But the choice should all be up to the user. But is it any different in stock android - can you uninstall the bloat: Gmail, Google Drive, Youtube, Chrome, etc? Can you even get rid of the Google Search bar taking up space on the home screen?

fyngyrz: The lesson Samsung *should* have learned from the previous generation:

Non-replaceable battery: Battery problem? Phone is garbage. Write off entire cost. Purchaser has nothing. Seller loses everything.

Replaceable battery: Battery problem? Send new battery. Preserve most of purchaser's value and seller's income.

@Melchiorum

I hate built in obsolescence. If people want to change their phone every 12 months it should be because the manufacturer made a compelling case, not because the previous phone was programmed to die prematurely.

And it is you who clearly does not have a clue - Built in obsolescence reduces the imperative for the manufacturer to innovate.

Ah, the 'bloated' TW skin? Oh for the purity of 'stock' Android, with all the lovely new features coming in Nougat, things like split screen, pop-out video windows, all soon to be available, but which TW enjoyed already two years or more ago... bloat.

I'd love one of these. Replace the fixed friable glass back with a removable robust plastic back of old, slightly fatter to allow room for the (replaceable) battery, and I'm all in. Before you shoot me down for blathering on about replaceable battery, I've just had to replace the battery in my Note 4 due to diminished capacity causing it to crash when the camera was used owing to voltage dips.

Um, clearly not. The first challenge is how not to lose the damned lid.
