'Digital only' lenses - are they a good investment
It's my intention to stay away from APS-C only lenses as much as possible because I hope that we do see a move to full (35mm) sized sensors in consumer specification digital bodies. This is mainly because the area most adversely affected by the smaller sensor size is wide angle, and that's what I us...

'Digital only' lenses - are they a good investment
I wonder if technology like KM/sony's antishake could be made to work (on one plane/axis) with in camera processor stiching together data from the sensor to capture wider angled images. Ie pivot the sensor to collect more light...or pack more pixels on one chip, but have the additional light recepto...

'Digital only' lenses - are they a good investment
Hi all, If you really do have the lenses which give you the results you need/want then who cares a fig If they are a good investment or not? The real reason there are two, (or three sensor 'divides' If you also include four thirds), is because they both have clear down sides of one sort or ano...

With my MX cameras (and a few other odd K-mount film bodies) 20mm was the widest I ever needed. The 12-24 covers that wide end and more on the APS-C sensor. It's a great lens, too. I also use the 16-45 as a general "walkabout" lens. It's a great lens.

I should also mention that the coming Nikon D3 is rumoured to be full frame or at least come out very close at 1.1 cropping factor. Again, what does this tell you? This rumour has been circulating around for a very long time, even before the D40 was announced..... I see no reason for this debat...

Hi, "I see no reason for this debate about the physical size of the sensor" Just to say that many thousands of people disagree with this point of view. That is why Canon sell so many full frame cameras. They have distinct advantages over smaller sensor cameras (as well as some downsi...

'Digital only' lenses - are they a good investment
Hi, "Will you be able to tell what are the problems with the current throat size if used on full frame? I'm a bit confused" I think various people have tried to say that the Pentax K mount is simply too small to accomodate a successful installation of a full frame digital sensor and ...

Obviously I must be missing something here.... If the pentax 'K' mount was large enough for the full 35mm frame, and it was, then why would it be too small for a digital sensor the same size....??

Now, I'm not an expert photographer, but I am a computer programmer. The physical size of the sensor doesn't have a bearing on the digital data you get out of it except insofar as you hit the physical limit of each pixel sensor's width for a given resolution. In other words, a 10mp 35mm sensor is go...

'Digital only' lenses - are they a good investment
with the way the sensor moves in the pentax, for the shake reduction, i wonder if its possible to develope a camera that can capture multi images, with a one pixel shift, and merge them....like a sixty mp still off a 10 mp sensor.... there's also the real possibility that you could develope a sen...

'Digital only' lenses - are they a good investment
The main thing is this: * The smaller the sensor, the small the photo-sites and the more susceptible to noise they become. * So... the larger the photo-site the higher the ISO can go (especially with CMOS, rather than CCD sensors) A case in point is the Nikon D3. Check out the ISO rating on it ...

'Digital only' lenses - are they a good investment
With current technology the sensor size is a factor in the amount of noise especially at higher ISO's - that's one reason why the 7MP sensor in my wife's little point and shoot produces results that are very, very much poorer than the results from my 6MP DS. Even if we ignore the fact that there ...

'Digital only' lenses - are they a good investment
The lack of moderate wide primes with good max apertures is a GLARING omission in the pentax range which is frankly inexcusable for any decent system. The situation could be helped considerably if Pentax would just put back into production a few of the primes which it made until just a couple of ...

here's an interesting thought: you slap an aps sized d lens onto a pentax fullframe dslr, and the sucker actually works, but the camera only uses the area of the sensor covered by the lens....therefore the 18 mp sensor (originally intended for the 645d) only uses 10 mp's worth of image area....then...
