When you use ridiculous words like "amateur" and "professional" to describe aspect ratios in this context, you're practically demanding to be ridiculed.

Lars V's response was about as measured a...

I personally think that 4:3 is a preferable aspect ratio in general, but any one that you pick is going to be a compromise.

There are good arguments to be made for 1:1, 5:4, 4:3, 3:2, 16:9 - and...

Yes, brain fart on my part. They both cover FF. That was my point anyway, that the assumption that one should be much smaller than the other - when they have the same focal range, same aperture,...

330g ain't bad.

$1500 is not cheap, though.

I don't get it, why would one 70-200/f4 lens covering APS-C be significantly smaller than another 70-200/f4 lens covering APS-C?

For an objective size representation with no perspective confusion,...

If you have an E-M1, you can also use a 4/3 adapter and get the Olympus 50-200mm 2.8-3.5 with a 1.4x TC.

That will get you out to 560mm eq. at f4.9. And is super cheap these days (I've...

"Try comparing the A6300 to the 7 year old 7D indoors. I don't know if it is due to sensor noise or what, but mirrorless has real problems when the light gets a little low."

I'm...

Erm, isn't the Panasonic-Leica 100-400 literally what you're looking for as a replacement?

Or if it isn't the focal length you want but instead the field of view, you can just use a 40-150/2.8...

marcio_napoli - why use digital medium format at that point instead of 4x5 film? It would require a similar set-up, similar shot discipline, and the initial set-up costs are much lower. Portra 160...

Great shot, havoc315. Very impressive stuff.

Battersea - the answer is yes, that is what M4/3 is all about.

You can get essentially any combination of size and features that you want.

Ultra-tiny bodies like the GM1 or E-PM2, mid-sized...

Ah, you're right, they're comparing a 7D, not a 7D II.

Did the 7D II (or any modern DSLR) improve on VF blackout times compared to the 7D?

Sibuzaru - if you're interested in paying $3500 to get a 140-400 f5.6 lens, then I guess it's nice enough?

Yes, there are no "weather-sealed" Sony E-mount bodies yet, according to the standards of any other manufacturer.

Canon, Nikon, Olympus, Panasonic, Pentax, all refer to "splashproof" and...

The OVF / red dot sight worked well for following the relatively predictably action of a bird flying when there was only one thing in the frame that you needed to accurately track.

I'm not sure...

A 9x12" magazine cover doesn't require more than 8MP of resolution...

"Medium format is , at a minimum, 6cm on one side."

Alas, if that were true, Hasselblads wouldn't be considered medium format. These are (nominal) dimensions of the medium format film that...

Yeah, it seems like the same process control that was allowing Sony to get such good yields (and thus low prices) for their 135-format sensors seemed to be able to give good enough yields for MF...

Indeed. This happens to be, specifically, full frame 645 medium format.

From a practical point of view, full-frame best used to refer to lens vs. sensor coverage.

You can have full-frame 16mm...

Why would anyone bother competing with them?

You're talking about a market that sells, maybe 20,000 or 30,000 units a year, total. It's just not worth it.
