Originally posted by TaoMaas When we say that these lenses can cover FF (and I'm also thinking about Pentax DA lenses here), does that take into account the amount of image circle needed to cover sensor movement for in-camera shake reduction?

Quote: Sigh. Again - having a lens mount big enough to fit a FF lens does not mean that the body is big enough to fit the sensor and related electronics.
Why not? If Moore's Law holds some truth, the image processing capabilities of the non-sensor electronics will shrink relative to their capabilities.
You're trying to put up a physical design barreir that has been broken many times before. The sensor's surface area can stay constant while there can be a dimunition of other electronics.
Note that some NEX bodies actually have the lens mount sticking out past the rest of the body!
Sony designed it that way. Ask them.
Quote: It is foolish to expect Sony to release a FF NEX. The NEX lenses are designed for an APS sensor. Sony would have to throw away all their existing NEX lenses and design and release brand-new E-mount lenses which can cover a FF image circle. They'd be in the same boat as most DSLR manufacturers are where they have to support both APS and FF lenses.
So you are saying Sony is foolish for designing it to have both an FF E-Mount and have the lens outsize the body, but that this is all really just for APS-C?
I agree, Sony is foolish, for losing money amongst other things, but they are clearly anticipating E-Mount being FF. They went so far as to release the mount solely on an NEX body. Is Alpha gone? We don't know. but anything new has FF built in even though for proportionate sizing and the "EVIL is small" mantra, this seems counterintuitive.
As with past lens mount abandonments, I predict that APS-C mount lenses will eventually be dropped. Both lens and sensors will be FF. This consolidation of design, production, support, marketing, and distribution will save the industry enormous $$$. Right now, sensor costs occupy that space. As FF costs are amortized, that capital will start to flow the other way making it cheaper to include FF through the line.
Quote: And, again, imagine mounting a 70-200mm F2.8 on an NEX body. Ridiculous!
Did you just see Sony's newest NEX lens announcement?
Sony E 18-200mm f/3.5-6.3 OSS ( NEX ) - Review / Lens Test Report
Tell me again what's ridiculous?
Quote: One final note on the lens mount thing. If
Wikipedia's lens mount info is accurate, the Four Thirds DSLRs actually have the same size lens mount as Nikon's FF DSLRs! Will you also claim that Olympus was always planning a full-frame 4/3rds camera, because their lens mount (~44mm) was plenty big enough to fit a FF lens? The micro 4/3rds could probably cover a FF sensor also; some 35mm rangefingers have similar size lens mounts.
In other words -
please stop beating this dead, meaningless horse.
Yes. All manufacturers likely designed the lens mounts to eventually hold larger sensors once sensor prices dropped due to economy of scale opportunities. This would force consumers to re-purchase (reinvest in economic terms) in the technology to continue the revenue cycle.
It's been done before, they'll do it again.
