Macro photographers often stop down to very small apertures to maximize the razor thin depth of field when operating at such close focus distances. Smaller sensors have greater depth of field than ...
While most photographers prefer fast lenses that range down to f/1.2, are there any lenses that go smaller than f/32? If there are, what is so special about those lenses that an aperture of f/32 ...
Given a sensor size, the diffraction limit (and cut-off) are determined largely (entirely?) by the density of pixels on the sensor. With the trend of ever-increasing megapixel counts, this means that ...
Is there any way starburst diffractions could be captured with a fixed f/2 smartphone lens? [closed]
There's been some controversy surrounding the publicity camera samples for Nokia's new flagship smartphone, the Lumia 920. First it was shown (and admitted by Nokia) that the stabilised video footage ...
I'm looking to try out macro photography and have a rental of the Canon 100mm 2.8L IS and the MT-24EX flash to try out on my Canon 7D. I've been reading that with the flash, you can stop down to ...
I'm curious if very short exposure times (say 1/8000 or even 1/16000) would cause noticeable blur due to diffraction. To achieve very fast shutter speeds focal-plane shutters start to close the ...
The reason I ask is that f/18 on a 24mm lens = 1.5mm, and f/18 on a 180mm lens = 10mm. I thought diffraction is due to the small physical size of the aperture, rather than the f-ratio, yet I only ever ...
Do smaller apertures provide more depth of field past the diffraction limit, even if peak sharpness suffers?
In Understanding Exposure (3rd edition, on page 48), Bryan Peterson has what might be called a rant against modern on-line conventional wisdom about diffraction limits. Answers on this web site are ...
I've seen the term used, but what is a "diffraction limit", when should I worry about it, and what undesirable effects are a result of it ?
