how do you handle this?

please show examples or I can find answers on google myself

thanks in advance

I used to shoot my SD1 Merrills in low res all the time.

Low res gives you 10um pixels, slightly bigger than even than the SD9's 9.12um at high res.

On a per-pixel basis larger pixels give a higher MTF at Nyquist (0.5 cycles per pixel) but visible false detail above Nyquist. At 10um, Nyquist is 50 lp/mm quite within the capabilities of a good lens.

Most of your image is not sharp which is why Don asked his question, so what did you mean by "this"?

Ted? English please?

and I dont have a LENS PROBLEM.

Never said you did.
