full frame v crop....... numpty question maybe or not.....
AF speed has absolutely nothing to do with sensor size :roll: Nada. It's down to expense - big, expensive FF body and they put in a faster CPU, a more sensitive AF sensor, plus perhaps a larger supply. It's also perhaps down to marketing as well. They'll obviously want something 'tangible' for the ...

full frame v crop....... numpty question maybe or not.....
As we only use the central area of a full frame lens on our Pentax DSLRs, then we are using the area of the lens's coverage where the corrections are best and the quality is highest. Thus much of the fall off that we find at the edge of a lens is removed. Would like to add something to that. Since ...

full frame v crop....... numpty question maybe or not.....
Since the APS-C sensor is smaller then FF we need to enlarge it more to get the same print size so the extra sharpness that you get from only using the middle of the lens is payed in a bit again. That would assume the same pixel density for the FF and APS-C sensors we were comparing. So if both...

full frame v crop....... numpty question maybe or not.....
Sorry but I can't fully agree with that John because lens performance is truly only about physical dimensions. What I'm trying to say is that if the same lens is mounted on both sensors with the same amount of pixels the lens will be sharper on the FF sensor. With your example. for example yiel...

Eyes of Laura Mars
I see PP as a necessary but kind of artificial process in digital photography It's one of my pet criticisms of modern photography, particularly amateur photography, that once photoshopped, there is a depressing sameness about so much work. All skies are perfect summer or heavy 'moody' cloudy. All...

I, like many others, use the Arctic Butterfly. If you go to a camera shop they will probably use one of these and charge you £40 (which is the price of the basic kit). Personally I recommend buying the travel kit. It cost around £100 but will pay for itself in a couple of years.

Have you tried a proper blower yet? The Giotto Rocket is a good example. I bought cheap and regret it. Mike

sensor/lens cleaning?
If you have a charged up battery it should clean the sensor as it only shakes it a bit. I have it set to shake each time the camera is switched on - not everyone thinks this is a good idea. There's a knack to wet cleaning with swabs and I would regard that as last resort but since you have them ...

sensor/lens cleaning?
Well I think you need to wait for better advice than I can give but Google Eclipse cleaning swabs and I think they tell you how to use them. This wasn't a lens cleaning kit was it? Mike

sensor/lens cleaning?
Hi Emma, I always try to clean first by a blower (I hold the camera body lens mount down and blow up so that dust will fall out, hopefully), then with artic butterfly, and if that doesn't work with swabs and eclipse 2 fluid. NB your GX10 will require Eclipse 2 not Eclipse due to the tin-oxide...

sensor/lens cleaning?
again no idea and i did fully charge by batt before doing the sensor cleaning but still run out:x If you've fully charged the battery then it should hold the shutter open in the "cleaning" position for quite some time. I would estimete that I've engaged the sensor cleaning option for not more than a...

sensor/lens cleaning?
I got the pentax ccd sensor cleaning kit from srs microsystems when it was a lot cheaper - at the time it was around £28 but i see that pentax have virtually doubled the price!. i still think its worth the money as it does an excellent job and i can recommend it.

Scanning
I agree with SRS that the Plustek is a better option. When I've used my cheap neg scanner I spend more time adjusting colours and cleaning the image up than it's really worth.8)
