comment How can you photograph backlit scenes without getting lens reflections/flare?
If the OP is using a filter he should definitely remove it when shooting into the sun like this, never mind its quality. It can do no good whatsoever to have it there, and it can very well be detrimental.

comment Why are digital cameras said to suffer more from chromatic aberration than film cameras?
There is also the rather thick (~1mm or so) antialiasing/UV/IR filter glass that sits directly in front of the sensor. In the corners of the sensor, incoming light will hit at an acute angle (unless the lens is telecentric) and this can do nasty things to the colours. Especially on say some Leica M-mount wideangle lenses where a small-diameter rear element is deeply recessed into the, well, not the "mirror house" but the corresponding cavity in the camera, close to the film plane. This doesn't happen with film. Microlenses can only do so much to overcome this.

comment How do I properly understand what f-stop is?
Re your statement about flange distance versus focal length: It is true for SLR cameras, because you need to move the mirror out of the way before taking the photo and thus the mirror-box needs to be free of obstructions. For mirrorless systems it is not necessarily so; I have an old Russian, Zeiss-designed 35mm/2.8 for Leica that pokes so far into the camera body that it almost touches the film plane. (That said, on digital cameras retrofocal wide-angles generally seem to be the way to go, just as on SLR cameras, to avoid corner pixel shading and other problems.)

comment Does the Fujifilm X-E1 work with Ubuntu?
The camera as such could not care less about what operating system your computer happens to be using, any more than your car or washing machine does... Are you trying to ask whether there is a RAW converter that handles X-E1 files and runs on Ubuntu? Or are you concerned about connecting the camera to the computer via USB and downloading the photos that way?

comment What are general rules for ISO settings when using a flash?
Essentially there is no difference between direct flash and bounce flash in this respect, although the flash has to work much harder if you bounce it because the light is spread out more so less of it falls on the subject. My approach to indoors flash, for the record, is to set ISO/shutter/aperture to whatever combination gives me the desired exposure for the background, and then add flash to give proper illumination to the foreground. This means that I don't actually pump the flash all that hard, as the overall exposure is in the ballpark to begin with. This gives a shorter flash recharge.

comment Do point and shoots exist which can get close to what DSLRs can produce? (And where could I find one?)
Aye, and look at all the image noise it shows at a mere ISO 200 :) My DSLR is way better in this respect and is almost ten years old now.

comment Does the time required to stop down the aperture affect the shutter response time?
Whoa - talk about mirror bounce on the D80! Consider me impressed that our cameras actually work at all, considering how much is going on in there every time we press the shutter button :)
