Well may well see small FF

So how big is Sony's FF 24-70mm f/5.6?

About as big as their 16-48 f/4 for their crop NEX. Which is...

Oh no! They don't have either one yet! Oh man, you totally called me on that and rendered my theory totally incorrect! Making FF lenses as small as m43 is clearly physically impossible, just like dougjgreen1 said.

If only I had realized that Sony was bad about making lenses I could have posted something like "If Sony is willing to make slow lenses (a big if) for their FF system to reduce size..." and have prevented this! Now Full Frame will be bulky forever

You miss the point. You can't go into a store and choose any lenses that would be physically possible to make, only ones that exist. Sony do not and will not produce a FF 24-70mm lens of the same size as the Panasonic 12-35mm lens, so whether it is possible or not is not a useful consideration for the users.

Typically, FF users accept larger and bulkier bodies and lenses because they think they get something out of it. Some actually do. Just for fun I made a list of the 10 most popular FF lenses for Canon and Nikon (including 3rd party lenses) and compared it to the 10 most popular M43 lenses. The lenses on the FF list were on average 3-400% larger than the ones on the M43 list. And no, they were not "equivalent", because that is not how those choices are made.

I don't miss the point. You can't go into a store and buy a full frame NEX either, nor do we actually even know if you ever could. This is all rumors and speculation, and I was pointing out a theoretical possibility for a theoretical camera. I'm most certainly not claiming they will make such lenses but for you to state they won't ever is ridiculous.

You claim FF users accept bulkier systems for some benefit, but how does that explain all the APS-C users of the Canon/Nikon systems who use the same lenses in similar bodies? Or heck, how about Four Thirds, with it's, say, 35-100mm f/2.0 lens. It's more than double the weight of Canon's FF equivalent (70-200mm f/4) and 25% heavier than the f/2.8 version. And that's not cherry-picked: Aside from the 3 kit versions, every zoom for Four Thirds was over 400g, and often nearly 1000g.

Where exactly can you say that FF is bulk when the SLR version of m43 was just as bulky if not more so? FT as never about reducing bulk, it was about reducing camera cost just like APS-H and APS-C (which was created at a time when mass produced FF was basically impossible). Mirrorless is about reducing bulk, and Sony is putting out a FF mirrorless. What's the point of that vs creating another A-mount if they're just going to make huge A-mount-like lenses with a shorter flange distance? When you consider that Canon's FF 50mm f/1.8 is smaller, lighter and cheaper than supposedly-small m43's 25mm f/1.4 without even equating aperture, I think small FF is entirely doable.


To step away from theory and speculate a bit: Sony is introducing FF to a system designed from the start to be compact and APS-C. It would be a quite sensible policy to adapt fast, bulky A-mount lenses and make the native E-mount lenses smaller and slower. After all, they seemed content to let their FF NEX camcorder use adapted A-mount lenses.
