Overly-enthusiastic amateur with an excessive budget and gear that is way too good for me.

comment What to look for when testing a wide angle lens before buying?
In that case, this question/answer should also help (and also applies to any focal length): photo.stackexchange.com/questions/12215/…

comment Do the Lightroom lens correction tools make good lenses less important?
I think this is hard to answer in a general sense. For most people it comes down to "how much is your time worth?", e.g. if you can afford a lot of time but not a lot of money, by all means spend less money on a lens and more time editing in Lightroom/Photoshop/etc. For many people, time is extremely valuable and even though it might be possible to fix lens (and other image) issues, it takes time that they'd rather spend shooting or doing other more important edits.

comment Why are these light trails large blobs of light instead of nice thin lines?
It looks to me like the smudging is a result of flare, caused by the oncoming headlights shining directly into the lens, which in turn causes internal reflections and produce a ghost image on the sensor.

Could you clarify what you mean about "the few with serious problems"? I assume this means some known problems specific to this lens? If so, please state what. If not: the accepted answer to the question you linked to applies just as much to wide-angle.

comment What aperture should be preferred while shooting the subject which is close enough, to get maximum sharpness?
Sounds like there is confusion over the term "sharpness". This is generally a property of the specific lens in question. But it's also important to understand depth-of-field ("area of sharp focus"), which is not really the same as sharpness, but is related.

comment Is it difficult to focus on 1.4F prime lens, and if it is how to counter that?
@AnishaKaul: OK so you now have 2 variables (aperture, focal length) out of four to work with. If you'll visit the link I posted or any other DOF calculator, you can plug in your sensor size and play around with the subject distance to see the effect on depth-of-field.

@StanRogers: exactly right, focusing isn't difficult; getting the subject into good focus can be.

Right, thanks for that, Craig. I should have phrased that better. I've edited it a bit.

It would probably help you to explore the relationship between sensor size, focal length, subject distance, and depth-of-field. It will help you understand this and your other question about f/1.4. For example: dofmaster.com/dofjs.html

revised Where to get community-based feedback on my photos online?
fixed url for Photo.net link; extra crud at end of URL was causing a 404.

comment Is Flash a Must-Have For Macro Photography?
You can avoid shake with a tripod. Thus I'd say, "a flash is not a must, nor a tripod; but if you don't have one, then the other might be" :-)

comment At what point does wind become a concern with respect to damaging a lens?
Right, thanks. I edited my answer to clarify. You probably don't want to use a brush on the glass surfaces.

comment What do you look for when choosing a photo sharing site?
I went with Zenfolio, but smugmug is pretty comparable.
