Do I use the 14.6mp resolution? I use it constantly. It's the main reason I bought the camera. I shoot a lot of wildlife, and the K20D body with its heavy cropping ability and fast buttons instead of menus made a lot more sense to me than adding a long Sigma lens to my K100DS.

I don't shoot less than 14.6 unless I specifically take a photo for internet posting, but that is rare.

I'm always worried that somewhere down the road I'll want a high res version of a photo and I'll be kicking myself that I used less than my camera's full capability. After all it's only taking up digital memory which is getting increasingly less expensive these days.

The resolution any more isn't so much about detail. It is about being able to do extreme cropping and still have enough image data to do large prints. If you can use the entire image you can do very nice 13x19-inch prints with an 8 or 10MP camera. However, since I can't find a zoom lens in the range I want, the size I want, the price I want and the quality I want having 14.6MP with a 250mm lens means I can get the shots I want, but I have to extreme cropping and if I want to print them large I need all of the resolution I can get. For me MP will stop being important when you can get a 25 to 30MP camera for $1500. This with the cropping I do and the 13x19" consumer grade photo printers will give me everything I could ask for.

Amen to that... I already wish I had brought a "better" camera for the Alaska trip we did last summer. I wish those shots were as large as possible.

Your limit will be the M lens more than the sensor.

That's a good thing, though. Oversampling has all sorts of benefits for the end result... it's filesizes and the costs of producing a 35-40mp sensor that are the real stumbling blocks.

You really think an M lens would be the limiting factor versus the sensor? How do you arrive there?

Is this a resolution issue? Distortion?

Using terms of analog systems, Threshold? Sensitivity? Resolution? Accuracy? Precision? How do you figure the output of the lens is less than can be represented by 6 million discrete points? I don't see it.

What were the specifications of analog film back in the day? Were M lenses that poor compared to film? I cannot see that either.

CORRECTION: I see, you are talking the 14.6 sensor... That is like a 24 bit conversion, analog to digital.

It's hard to say no... for my needs. Very useful when cropping is needed or I have little choice. I prefer full frame shots, since it's a personal thing - a method or discipline of mine I like to do.

I often print 16x20 images, so having a 10+ MP image is a good starting point if I need to crop a bit. Best wishes on your decision!

Cheers,
Marc

The K20 sensor is pretty much pushing the resolution envelope for all but the very best lenses, and is probably higher than most M lenses in normal picture taking situations.

I got ya. I first read that to mean the 6.1 sensor... Exceeding the resolution of the M and A lenses sounds great to me.

I have both cameras and the wife uses the K100d,.. Alot of times we take the same shot and the two don't compare at all, Of coarse I have the better lenses and she has the better eye. But the K20d is far better in IQ. IMO and Hers.
