Buy a 135 format?
No, don't see any point really. The APS-C sensor is good enough, imho. And it can only improve in the future.

Stefan, Why would Pentax charge the above prices you have quoted when they charge a lot less than the competition for the DMF? WRT new lenses, how many within the group have a 31mm Ltd or other 135 format lens? I see you have a D-FA 100 macro Stefan: Angle of View: 15 degrees (24.5 degree...

Buy a 135 format?
First two options are prejorative, as they make assumptions about size and cost. As has been said many (many) times before, the reason FF DSLR's are so big, heavy, and expensive is because they are aimed at the Pro/Journo market - who want big grips, long battery life, ruggedness, etc. Strip all ...

K10D, you need to have a base line, I could easily said entry level 135 format and you would come to the same conclusion for the price range. I don't know what you are getting at with the lens comment, yes I've one lens that fits on 135 format sensor so what about my other lenses? There is now a...

Base line are good Stefan. Having a poll on this is not going to change anything. WRT the 100mm lens, it does impact that lens more as its a macro. Just for the record, I also use mine on an APS sensor. Regards

...all you really have to do is change the actual sensor - no more work than putting a different CPU in a PC... Plus a bigger mirror, a bigger focusing screen, a bigger lightbox, a bigger shutter.... You could make a small FF camera, I am sure (and if anyone can Pentax can, they have made a speci...

Base line are good Stefan. Having a poll on this is not going to change anything. I was not hoping to change anything, just wanting to see if they would buy into a 135 system if Pentax would offer a similar camera as Nikon or Canon. By the looks of it many think they are fine where they are and ...

Well you did said my name :wink: APS-C DSLR will always be smaller because of the reasons Kris said. a bigger mirror, a bigger focusing screen, a bigger lightbox, a bigger shutter.... If they can make the 135 format smaller by some technique they can also do that with the APS-C DSLR. The same t...

...Having a poll on this is not going to change anything... K10D is correct in this... This topic, IMO, is purely subjective. For every reason to "up-size" the sensor, there's an equally (at least) valid reason not to. Boils down to opinion. Hard to quantify something like that. (And sometimes no...

Is there still a place for filters In a digital world?
I'd like to try UV photography but the UV passing filters start ~£200 which is too much for me, especially as I might find even my older lenses block to much UV. There is also a filter in front of the sensor that blocks UV so that's great the ones in the k10D and newer models also blocks infra-red ...

Does such a bag exist?
The Hadley bags always look a little too shallow to store a body with an average sized lens on. That's my impression anyway, I could well be wrong. I store the camera and lens in the centre section, vertically. Gravity may even help to let dust fall off the sensor....I admit that I have added a doub...

Lenses & spectacle cleaning
I wear glasses for reading & driving, and recently changed my glasses. The thought occurred that glasses come with a cleaning cloth (silk I think?) could you use this and the glasses cleaning fluid to clean camera lenses. Has anybody tried it, and what do people think about it. Regards

Lenses & spectacle cleaning
I wear glasses that come from Spec Savers. They provide a cleaning cloth with the Pentax logo on it. I have tried this on my Tamron and it seems to be OK. Spec Saver use Pentax lens I think. Les

Yeah the cloths are certainly okay, don't know about the fluids though but the coatings shouldn't differ so much I think.

Spec Savers use Pentax lenses, although they're not all glass, my reactions are plasti but work OK.

Lenses & spectacle cleaning
I use computer monitor cleaning spray if I buy a lens which is really grubby, it doesn't seem to harm the coatings. I've also used glasses cleaning spray although that stuff is a bit expensive. The main thing is to make sure that the cloth you use isn't abrasive and has no dust or grit on it. I t...

have you seen the state your glasses get into after wearing them while cooking with a frying pan No. I can't see a thing after frying! :lol:
