Re: Lens cap 15mm v 14-42 2R

Personally, I think a 16mp sensor on M43 is the optimum size because it is capable of making 16 x 12 prints at 288 ppi and that is enough for me. Cramming many more pixels on the sensor will only increase the possibility of diffraction limitation at larger apertures.

John - there is no correlation between pixel density and diffraction effects so long as you're talking about an image of the same output size. Diffraction effects will increase the spreading out of a point source (or edge) in geometrical terms. No matter how many pixels you place on that spreadout it's still the same amount of spreadout. Of couse, if you go viewing at 100%, then the image size increases as the MP go up, but then you're looking at a larger magnification.

As to whether 16Mp is optimum or not... as the owner of a 20Mp m43 camera I can definitely say that there is a slight improvement in terms of distinguishing fine detail and also some slight improvement in DR and tonality. These latter two are probably more about the sensor tech than the Mp count though. In overall terms though the improvements are very small and I wouldn't lose sleep if I had to live without them.

There you go Zuiko everyone has answered the question you asked me...….
Why do forum members feel they must answer a question directed at me?
Just verbal diarrhoea.
None of it relates to what I would have said but that's this forum …

Why do photographers prize detail so highly? Personally I find less is more in many areas, and that includes photographs. Pin-hole for example is quite hazy, but generally more engaging because it forces the viewer to ask more questions.
Your mpg will definitely vary.

Yes, my question was directed at you but we are in a public part of the forum and other members are welcome to comment. Had I wanted your views only I would have sent a private message. You really do seem to have a problem with forum etiquette.

Very good point Steve, we hunger for sharpness and detail, but really should be reading the story that the photo tells....

As Cartier-Bresson famously said "sharpness is a bourgeois concept".

In years to come people looking at your images won't say, 'gosh that looks sharp, he must have had a great sensor'. No, they'll look at your images and say, 'that's great, he captured the moment well, I can see what he was thinking about'.
Images / photos that provide insight are worth so much more than a tack-sharp soul-less image that happened to be in front of the lens when you clicked.

Capture as much detail as possible - you can always throw as much as you want away in PP. You can't do anything with detail you haven't captured in the first place.
