Originally posted by TaoMaas Well, if that's true, then it would also be true of Minolta legacy glass, right? I, for one, am doing exactly what you think folks won't do because I think you're wrong about how some of these older lenses will perform. Sure...they all may not make the cut, but I'm thinkin' a lot of what I have will far out-resolve any display media I'm likely to use. Also...if I buy a FF camera, I won't be shopping for a 24-70/2.8 zoom, so you can stop padding your guess. lol
Fair enough.
But Minolta (like Canon) cut off a foot to move to AF when they dropped their manual focus Rokkor mount for the current A-Mount. But that was in the 1980's. Lost me as a customer. I went to Nikon. Still, Minolta easily held onto 3rd place in SLR sales, and for awhile was pretty much outselling Nikon.
If your photos are likely to outresolve your media for viewing, you do not need FF, unless you are the King of Cropping.
Pentax FF will require something like a 24-70/2.8, and likely a 28-xxx/3.5/4.8 for the prosumer crowd. This will NOT be cheap glass.
FF only makes sense for Pentax is new glass is also purchased. If it's as much for legacy glass, it's a dead idea.
The idea of Pentax 14-24 and 24-70 lenses with in-camera SR and a 24MP FF sensor makes me shake all over. However, such a combo is an arrow straight from the quiver aimed at the 645D.
Originally posted by Asahiflex You obviously don't know what you're talking about. Please show me proof that a LOT of the old manual K/M/A focus glass will struggle on FF. I've put emphasis on the word " LOT" as I don't accept a single example from the M85/2 to prove your point, or shots from $5 no-name lenses off eBay.
Nah! I'll just quote Pentax USA's Ned Bunnell. I think he knows more than you, for sure:
NED BUNNELL: April 2009 Anyone that is currently using a full frame sensor 35mm camera knows that they exact a high price in terms of the lenses that perform acceptably. Many lenses originally designed for film fall short in terms of distortion control and edge-to-edge sharpness when used with a full frame sensor. I have a good friend who currently shoots high-end weddings in Southern California with a 5D. While he loves the fact he can now use his wide angle lenses, he has quite a few lenses he's shot with for years that he can no longer use.
In our case, if we developed a full frame camera, it's likely that very few of our recent DA lenses (those designed for APS-C) would be able to properly fill the viewing area of this new sensor. And although we have some wonderful FA lenses, like my favorite FA 31mm Limited, I'm not sure even this lens would be up to the optical challenge.
I know that our engineers have studied these issues and would probably not agree totally with my simplistic explanation. However, I think it's important to understand that going to a full frame sensor means not only having to design a brand new camera from ground up, but likely a new line of lenses that meet the more demanding optical requirements.[my emphasis]
It's clear that there is a place for full frame cameras, but it currently is a small part of the overall SLR market. Due to the total cost of ownership and increased demands shooting with full frame images, the majority of cameras sold will still use APS-C, 4/3rds type sensors.
Despite some of our desires to always want newer, faster, better technology, I'm not sure that many of us would see a dramatic improvement in our photography if we were given a full frame sensor camera. Personally, I think we've hit the sweet spot with APS-C sensor cameras today. 12-15 megapixels is more than adequate for even your most demanding assignments, we've got far better control of noise, frame rates and processing speeds are sufficient for the majority of work advanced or serious photographers need and all of this is available at very reasonable price points, regardless of your choice of brand. Originally posted by Winder For people who use center AF and crop for composition in post the performance of the older glass will be just as good as it is on APS-C.
Agreed. But you just shrunk the market even more, which is exactly the point Ned makes above. The market will not contort itself to one person's shooting style. (Unless you are Cartier-Bresson...but he's dead).
My 2 bits about old glass is the weakness of WA lenses and flare control with digital sensors. There's precious little WA old Pentax glass as is compared to other brands.

What? I love my 85/2, but it absolutely requires a hood.
Then highest resolving lens I own is the A 50/2.8 macro. I'm not against old glass, but I see limits in it being used to justify a $3,000 FF DSLR expenditure for me personally, much less as an investment justification for Pentax. They will need to sell, and you will need to buy, a LOT of new FF glass to make the system fly.
