comment When should I consider an image sharp?
There is not enough information to know what is going on. It could be soooo many things or even just your perception. Note that you need to see images at 1:1 (100% magnification) to see the actual pixels, most cameras zoom-in further and interpolate after that which is why it can look blurry without being so. Otherwise, start by checking sharpness settings.

comment Where does the price premium of full-frame come from?
Without knowing the real reason, my intuition tells me its #2. Volume can reduce the price of most chain-produced item much more than the difference between component costs. You will see that there are even compact cameras which cost more than APS-C DSLRs and those are usually premium models which sell even fewer units.

comment What could have caused this splotch to appear?
Looks like an object in close proximity. I once had this happen several times and could not figure it out until I finally spotted it: an insect. Unfortunately, I have no idea if this is the case for you. Could be a drop of water or sweat even.

Break the questions. There are two here and one has been answered already I suspect.

comment Why are my photos taken with the Sigma 18-50mm f/2.8 coming out blurred?
In addition to being back focuses, as others said already, you are shooting wide-open. This lens does not get truly sharp at wide-angle until F/8 with F/5.6 being pretty decent.

comment Does a viewfinder cover really make a difference?
@Jasmine - Only with (D)SLRs which are the only cameras that come with a viewfinder cover or eyepiece shutter. Camera with EVFs need not worry about it.

comment How to tell if a digital camera shoots quickly
Some cameras have a pan focus mode which sets the lens to the hyperfocal distance in which case it no longer focuses when the shutter is half-pressed. All cameras with a Manual-Focus mode will not focus in Auto mode when MF is engaged.

comment What are the values in the white balance menu in D40 refer to?
0 is relative to the chosen WB. Each Preset, for example, Cloudy corresponds to a certain color-temperature in Kelvin. An adjustment of 0 means that there is no offset. It works similarly to EC where WB Fine-Tuning is adjustment over the set (Preset) or metered (Auto) value. When you set a Kelvin temperature explicitly, many camera disable adjustments.

comment Why is there a vertical line on the right of some pictures rotated with exiftran?
Why don't you just use nconvert? Never seen such an issue from it and before cameras did autorotation, I used it all the time.

comment Apple Aperture replacement
@bart - They now claim to be 4X faster (down from 10X two versions ago) but my tests align with this. Now that I just upgraded to LR 5.5 (was stuck on an old version previously due to a bug), I'll run some more benchmarks.

comment Apple Aperture replacement
@dpollitt - The one I use pre-import is PMView Pro. It's blazingly fast and means less time importing in Lightroom, plus no need to catalog images that are destined to be deleted.

comment Variable focal length for macro lenses?
Apparently, it's not the same as a zoom. I was not sure, so I asked a question about just that a while ago: photo.stackexchange.com/questions/21457/…

comment What are the pros and cons of the two Sony mounts — E and A?
@KartickVaddadi - Contrast-Detect AF is actually more accurate and most hybrid cameras like the NEX-5R switch off Phase-Detect AF in favor of Contrast-Detect in low-light. This intentionally sacrifices speed of focus in favor of accuracy.

comment What are the pros and cons of the two Sony mounts — E and A?
There is always some chances of missing focus and there is nothing in the mount which makes one more or less likely to do so. The brighter the lens though, the more light the AF system has to work with.

comment How to reverse command dial for Fujifilm X100s?
No idea if this is possible, not by official functions at least but I know what it's like. Last week I was reviewing the Olympus E-M1 and I kept turning the zoom the wrong direction. Nikon for a long time had the EC indicators and dials reversed, drove people with dual systems crazy!

comment Do UV filters serve any other purpose on modern lenses other than to protect them?
A clear filter would give you the same issues. Maybe a little less degradation but I haven't measured. Even expensive filters cause too much flare under some circumstances.

Don't give them ideas ;)

comment How do I move a photo in Lightroom after it's been added but not copied?
Actually, because LR thinks those files have moved and are not new imports, the metadata will be intact, including the reject flag. That means all the rejected ones will be moved but you can now select them by the reject flag and delete all of them together. It's a little more work but not as tedious.

comment Mirrorless Camera vs mid range DSLR — how to decide?
It was just a casual mention that the asker forgot to list about the most important (IMHO) aspect of comparing mirrorless cameras to a DSLR.

comment 28mm vs. 24mm (wide angle) for selfies?
Isn't a selfie supposed to be done holding the camera yourself? I thought that was the point. Otherwise, everything you say is right.
