comment Given the same sensor size lens, will a higher megapixel sensor give more “reach” then a lower one?
CoC can also refer to the visual acuity or the resolving power of the equipment. I would argue that the 24MPx sensor probably won't give you a much better image than the 12MPx sensor, so cropping it won't make much of a diff. I would expect the best answer to this question would involve a discussion of CoC and pixel density. High pixel densities have their own problems, such as increased noise due to less light per pixel.

Why haven't any of the 4 answers so far, used the term circle of confusion? Does it not apply here?

comment What prevents a f/1.8, 24 mm - 70 mm or similar range zoom lens from being made?
You pointed out several technical limitations, so then wouldn't the main reason be that. Why did you say it was a commercial decision?

comment Focus specifics in Samsung s5
@dpollitt, perhaps you could post a photo and an accompanying answer of your own where you have achieved bokeh and a focused target at the ranges the OP suggested, 2m from the lens. with a Galaxy S5 you can get bokeh if you snap a photo of an ant at very close range. good luck. theres lots of smartphone photos with bokeh, but none with a focused target at 2m.

comment Does shooting video decrease the life of a DSLR more than taking photos?
can you be more specific with your camera models?

comment How can I compose shots with tall buildings without boring sky dominating the image?
because if you don't offend them its not art?

You should be able to do this without "cutting" anything. You have a natural "blue screen" over which to superimpose your masterpiece sky pic.

comment Why is it called “macrofocus” and not “microfocus”?
@Skaperen, I can't believe you're getting upvotes on your comment, because the OP already stated that micro does exactly that as well. so that is not at all what distinguishes the term macro, despite what I believed, before I read the question.

comment Focus specifics in Samsung s5
@dpollitt, true, distance to subject is another factor. the OP said the subject is 2m away. you might be able to introduce bokeh if you get much closer, maybe 20cm?

comment Why is 18% grey considered to be in the middle for photography?
So let's say you've determined the perfect shade of grey for your exposure card. Now the question is how much light do I let fall on it when I register it with my meter? 18%?
