Pentaxian wrote: However, with FF frame cameras, you loose on the long end. Why? Regards, Horst Due to the smaller image circle of APS-C sensor, you need a shorter focal length than FF (a misnomer, if there is one, because APS-C is also FF, and so is medium format) to achieve the same results ...

I think these endless crop factor disagreements could be ended by stating the type of sensor the lens is to be used on. If we are comparing a 24mp APSC sensor to a 24mp FF sensor then the crop factor applies. If we are comparing a 24mp APSC sensor to a 36mp full frame sensor then it is irrelevan...

If we are comparing a 24mp APSC sensor to a 24mp FF sensor then the crop factor applies. If we are comparing a 24mp APSC sensor to a 36mp full frame sensor then it is irrelevant as you can simply crop the image yourself. The difference in image circle is always there, so the "crop factor" always ap...

But the crop factor is merely academic since the user can crop away 12mp to leave identical images. No? The second point is the one I am interested in. Again it only applies where we are considering equal pixel count. Where there is a 50% higher pixel count then it is back to an academic diffe...

It's too late now...... were stuck with old movie film sizes, but a FF 35mm lens could have covered a 30.6mm SQUARE sensor. That would have been about 8% bigger in area and highly cropable. The SR mechanism would probably be easier to construct. Mirrors would be bigger in one direction and smaller i...

The only reason we have smaller sensors in SLR's is because at the start FF couldn't be done. Now it can. That's actually not right. The first DSLRs as we know them now were full frame sensors, including a prototype from Pentax. Contax and Kodak went to market, but the cameras were very, very expens...

I will take an LX'D with the Nikon D4s sensor , Canons AF system, Sonys marketing and Pentax can then cock the rest up on their own:D

The pixel size from 16Mp APS-C to FF stays the same. So the resolution is not greater per given area. The pixel size of a 16MP FF sensor is bigger than that off a 16MP APS-C sensor so the resolution of the FF will be less, but give you a wider field of view

The pixel size of a 16MP FF sensor is bigger than that off a 16MP APS-C sensor so the resolution of the FF will be less, but give you a wider field of view Surely they'd be equivalent as a 16MP image will be comprised of the same number of pixels; eg 4928 x 3262 in the case of a K-5.

Thats why I asked if it was possible to articulate what we might look forward to in a future Pentax 'FF' DSLR (apart from the obvious extra cropping, larger prints and wide angle capacities). But so far I'm not hearing anything at all clear. I don't think the lack of clarity is all that surprising o...

Thank you Fletcher8 for taking the time to state what you were trying to get at and any misunderstanding that may have arouse. For your info, I have so far not been impressed for my needs as yet with FF, with the Sony A7 I purchased a month ago, this was purchased to find out what all the fuss wa...

But if you do stretch these things beyond such limits, into the realms of the unrealistic, then it just becomes a case of 'its not Pentax'. I also said that feedback & 'wishlists' had led to positive new developments - but these tend to be what is 'in sync with the design or natural evolution' o...

why would it take anything more than a software upgrade to add the capability to a Canon? I do not believe a software upgrade could make the sensor in a Canon DSLR shake. This particular example I am using is only that, an example, of different and incompatable technologies, to comment on where a de...
