New Pentax Firmware updates for 6 cameras
Interesting that contrast AF ( through sensor ) has needed a FW tweak for the 'mortgage requiring' DA 560mm :) Quite, I doubt there's many here that will see the benefit of this update. I'm not sure that the lens is even available yet.

LV Manual Focus seems better. I took 3 shots and they were all spot on..... usually they are a little bit out. - How would LV focus be off? It's through the sensor itself? i.e WYSIWYG

K5-II?
Lens wise I am very open to advice and thoughts, I am looking at at the longest circa 300mm lens. Having been reading around Nikon, Canon etc they mention a 1.6 multiplyer on the lens zoom is this some the Pentax has also as I have not found any info as yet. This sounds more like the crop factor r...

Full Frame getting closer ?
Hearsay and speculation. It's interesting that terms like 'full-frame' and 'APS-C' are ingrained in usage when the 'frame' of a digital camera is whatever size the sensor happens to be... (and I did grow up with 35mm)

Full Frame getting closer ?
Why the need for a full frame? The K-5 with an aps-c sensor gives excellent results that can crop down and still be printable at larger sizes. As for the need for Tokina to make 'FF' lenses, look in your camera bag and see what you all ready own. I use my DA-40 on my MZ bodies, and my DA35,...

Full Frame getting closer ?
I really find this a puzzle. If everything else is equal apart from the sensor size, eg a full frame camera that shares the body of the K-5 or its successor and even manages to be at the same price point (given probably not at first) would we still be asking why we need it? :? I appreciate we aren'...

Full Frame getting closer ?
According to the man at Canon the future of semi-Pro DSLR's is probably full frame. "the future of semi-pro DSLRs is probably full-frame, says Masaya Maeda, Managing Director and Chief Executive, Image Communication Products Operations at Canon" http://www.dpreview.com/articles/0336328811/cp-...

Full Frame getting closer ?
But camera makers are reliant on sensor makers, if sensor makers stop making APS C sensors as the price of FF sensors fall then camera makers will have no choice. I think im correct in thinking Sony are the only sensor manufacturer who makes DSLR and they are hardly making a wide range of APSC bo...

I think im correct in thinking Sony are the only sensor manufacturer who makes DSLR Samsung? Actually, I'm not sure if they make sensors, but I'd be surprised if they don't.

Full Frame getting closer ?
Pentax is certainly upping it's game. It was late coming to the digital SLR and the lens range was tiny and not of the quality or range that other manufacturers were offering. If it was not for the Pentax legacy kit that I have I probably would be using a Canon or a Nikon camera. Now it is a d...

Merits of APS sensor
Hi folks, My name is Ric Hochulski. I hale from the frigid north of Western New York, I shoot with a K5 with a K7 as a back up camera. I operate palladinphoto.com and have been involved in photography for over 25 years. All of my lenses are designed for full frame except for one a Tamron 10-24mm. Th...

Merits of APS sensor
Ric, welcome to the site. I mostly agree with your comments, but do you find that some of the character of a lens is lost on APS-C, especially primes (and usually older primes with some strange quirks!).

Merits of APS sensor
Well, I suppose you would even be better off, I you had only a 1/2 size APS sensor. This way only the extreme centre of the lens would be used. If you made it even smaller, you probably could get away with a single meniscus lens. On the other hand if you only had a full frame sensor, you coul...

Merits of APS sensor
On the other hand if you only had a full frame sensor, you could always crop it later to the APC equivalent size and you wouldn't have to worry about the edges when using FF lenses either. Given the same MP on two sensors though, cropping the larger sensor would mean smaller prints or more interpola...

Merits of APS sensor
Another advantage of the smaller sensor is more DOF, I've found when using the Q you can shoot a F2.8 and get plenty of DOF for landscapes and you get fast enough shutter speed to avoid have using a tripod. Obviously this is a disadvantage for portrait photographers. I still impressed with the...

Merits of APS sensor
I agree about the DoF; even with my K20D I'm using f/9.5 - f/11 to get a good depth of field (it took me a while to realise I didn't need to use f/16+ as I'd been taught years ago for slides). One of the other advantages is smaller size/lighter weight, both of the camera itself and the lenses -...
