This is another point that the peanut gallery is generally missing.
A small, lightweight camera is pointless without small, lightweight lenses.
And there are some very hard physical restrictions that come into play when designing lenses. The Shorty McForty is about as small and lightweight as a lens that covers the full 135 format image circle is going to get, and just look at all the people bitching because it's only f/2.8. If you want faster-than-f/2 in a normal prime, you're not going to get much smaller and lighter than the Plastic Fantastic. And if you want something that fast and either wider or longer, it's going to get really big and heavy right quick.
So, if you want small and light, you'll either have to go with something slower or that doesn't have as large an image circle. And probably both.
YES. small wide-angle to standard lenses are important. This is EXACTLY why I would love to get a small Canon FF mirrorless body (size like Minolta CLE) with an electrified Leica M mount, call it Canon EM.![]()
You surely know, how really small many of those M-mount fixed focals are? All of them built for 135 image circle. Available all the way to f/0.95 not just f/2.8. I am sure, it is possible to build a 40/1.8 lens for a FF mirrorless cam which is still smaller than the EF 40/2.8 pancake.
Zooms are a bit tougher, but some constant f/4 "kit-zoom", say a Canon "EM" 24-70/f 4.0 IS for FF mirrorless could for sure be quite small. I would even skip manual focusing gear and ring, since i never use it anyways. And 90% of users do neither. And those video guys shall go buy proper Canon camcorders rather than trying to cheapskate on our stills cameras.![]()

May be you are thinking about SLR lens. For range finder ( or mirrorless)lenses, it is different. The wide angle lenses can be made smaller (not necessarily lighter). Summicron 35mm is only 1 1/4 inches outside of the camera body. Skopar 25mm f4.0 is also 1 1/4 inches outside of the cameras body. A M4 body can be pant pocketable with either lens.
You should care if you want it to be pant pocketable. None of the existing normal or wide angle lens will make the camera to be pant pocketable ( not even the 40 f2.8 on a Rebel).Lee Jay said:Rocky said:TrumpetPower! said:And there are some very hard physical restrictions that come into play when designing lenses.

Since wide angles and middle-focal-length lenses are the smallest lenses in the kit, generally, who cares? A 70-200/2.8 isn't going to get smaller because of closer back-focus distance, and that's the one that's sizing my kit.

Rocky said:A lot of people seems to be disappointed that the Canon Mirrorless will be a G1 X sized sensor , not the FF or APS-C that they are expecting. For me it may be a little bit over reacted. In order to make it "smaller and lighter" canon have no choice but not to use FF. As for G1 X sized sensor, the multiplication factor for the focal length is 1.85 ( based on width) or 1.7 (based on height). Is is necessary to get disappointed because it is not 1.6 multiplication factor??? For me, if Canon gives us FAST AF(or good MF, like the Leica M) and smaller lenses, I will be happy with a smaller sensor.
RLPhoto said:This is good stuff, if canon would be more daring like it used to be, it could make a compact system with super speed primes and a large sensor for general photography. Who want to lug the DSLR around all the time when just a small mirror less and a 35mm f/1.8 on a FF sensor would be better.

Right! And for a mirrorless a version 2.0 of such a lens would be even smaller and lighter. No rangefinder coupling stuff, no f-stop ring, as far as I am concerned, no MF gear/ring, but a hi-speed Ring-USM AF drive.
I would love to use such a beast natively not on an anachronistic Leica M rangefinder but on a hi-end Canon FF mirrorless camera equipped with a modified 5D3 sensor [with in-sensor phase AF] with a non-Leica pricetag.
Wouldn't that be something? Canon would sell 'em by the millions.![]()
pharp said:Whether you want to believe it or not, there is [I believe] a large market for a more compact [probably mirrorless] prosumer 7D or 5D camera. THATS the market they should be going after, but seems unlikely since it'd cannabalze existing line. Smaller/lighter is usually better. Nikon still lists their old style MF lenses on their website - I've always wondered how well they sell. I would really go for some FD build MF only lenses.
moreorless said:I'd say just the reverse, adding in AF and other electrics is going to increase the size a good deal as we can see with a number of mirrorless primes that are larger than there manual FF rivals. Isnt theAvTvM said:Wouldn't that be something? Canon would sell 'em by the millions.![]()
As I said I can see a (smaller)market for a mirrorless FF camera based on primes but pretty much any zoom besides an kit standard or perhaps a very wide UWA doesnt seem likely to balance well to me.

I'v heard this alot but so far on digital the reality doesnt seem to match up, existing ultrawides on the NEX almost all perform poorly and the options on m43 are neither shorter nore cheaper than you'd expect from an SLR.
Zeiss does not make lens for m4/3. They are for FF only. So are the Leica M mount lenses. If you look at the rangefinder lenses, both Leica and Zeiss are Retro-focus design for anything wider than the 28mm (FF). That is due to the sensor require close to vertical (60 degree minimum??) incident angle. After multiplication factor, you will not have a ultrawide from either manufacturer.RLPhoto said:moreorless said:RLPhoto said:Another advantage for Mirrorless is truly awesome ultra-wides with pin sharpness to the corners is possible.
