Re: you have a narrow-minded view of the benefits of compact size

only for lens designs that are less than the registration distance plus working distance of the lens - which is why the 40mm pancake lens could be developed on the EF mount.

so again, it's not a one size fit all solution, and only effects a majority of lenses that by nature are not the largest in a working kit anyways.

the biggest benefit to these (assuming larger sensor MILC's) are prime lenses or zooms under the nominal registration distance of the larger DLSR cameras. (ie: 16-35,10-22,etc,etc). once you get around the DSLR registration distance and above, the differences are minor. consider there's hardly any savings in size to the 24-70 FE's versus the 24-70 canon. and certainly not for 70-200.

The savings really are just for the working few that work with primes or ultrawides - which is why partly it's consumer adaptation is fairly low. the longer lenses either don't even exist and/or if they do (18-200mm for sony E mount) they are ungainly and awkward.

the only place that seems to do well for a kit size is the m43's and Nikon 1. (partly the reason I think Nikon made the RIGHT choice on sensor size, and sony and canon has made the wrong choices) is that the IQ is atypically "good enough", and the kits are much smaller regardless of focal length.

Check out m43 / Nikon 1 / NEX / EOS-M with DSLR lens, all with appx. 80-300 telezoom in Camerasize


It generally bears out what you say, but somehow the NEX telezoom seems to have benefited from the shorter registration distance.

actually it's the exact same length as the EF-S 55-200mm (108mm), 7mm smaller diameter and 35g's difference in weight.

now the 1 and the m43 .. you really do get the savings.

even though right now the 1 lags behind .. i do think that Nikon tactically made the better long term "small system" decision because you could carrry a small equivalent system of lenses in a very small kit.  no one else can really make that claim.
