comment How doable is a Nikon mod for the Minolta Rokkor 58mm f/1.2?
Unless you can shave quite a bit off the rear of that lens, I'd guess you won't be able to focus more than a foot away. The Canon FD mount is 42mm, so the FD-EOS difference is less than the Minolta-Nikon difference, and, well: photo.stackexchange.com/questions/9146/… . FWIW I got an old u4/3 body so I could use my Konica and Minolta lenses. It's not as good as my DSLR, but it sure beats film.

revised Looking for a reasonably priced wide angle lens
corrected the name of the lens. I assume you meant the 17-55, not the ~$850 15-85.

comment Looking for a reasonably priced wide angle lens
Did your camera not come with an 18-55?

comment What type of wide-angled lens is the best option for photographing rooms in a hotel?
How are you going to use your pictures? Just put smallish versions (600-1200 pixels along the longest edge) on your website? Or larger images, and if so, how big?

comment Why picture quality decreasing with very big apperture?
When you change aperture but not shutter speed or ISO, your exposure will change. From f/12 to f/32 is about 3 stops, so if you kept your shutter speed and ISO the same but changed aperture from f/12 to f/32 you'd get 1/(2^3) or about 1/8 as much light in the f/32 picture as the f/12 picture. If you use a longer shutter speed to compensate, you need to keep the camera steady (for example, put it on a tripod) or else the movement of the camera can cause the picture to be blurry.

comment Software to keep track of pictures taken
It requires some discipline (manually taking meta-pictures), and may not work for you, but is "using additional pictures as metadata" a solution? So when you're about to start taking pictures of a swimmer, take a picture of the piece of paper with their name on it (with your finger or a pencil pointing to the name if the sheet is crowded), then take the pictures of that person. Or, take the pictures of the person then take the metadata picture.

comment How to not be ignored when talking to another photographer with significantly better gear?
If they're professionals, and on the clock, they're probably more interested in doing their jobs than talking about them. I'd be pretty irritated if a non-programmer I didn't know wandered into my cubicle and started asking me why I chose to use Python rather than C, or started making guesses about what kind of application I was writing.

comment Do third party extenders for Canon exist?
Brand still matters even when there's no glass. You may want to maintain communication between the lens and body. You want the physical connection to be secure (not wiggly or wobbly) and it needs to be able to release easily when you want to take it off. Cheap adapters, with less attention paid to the build or with less quality control, may not fit as well, or could warp over time, or paint flakes or metal shavings could come off and contaminate your sensor.

comment To get a really good photo, editing is necessary?
I'd take a look at photo.stackexchange.com/questions/1769/… . Also photo.stackexchange.com/questions/8142/… which touches on the issue.

comment What's an easy to use “large sensor” digital camera?
Superzooms usually have P&S-sized sensors (e.g. the SX10 had a 5-100mm lens on a 5.6x crop sensor for its 28-560mm-equivalent focal length). Are you specifically looking for a large sensor, or just anything that can give your friend a lot of flexibility?

comment Canon extender 2x III with 70-200mm F4L vs 100-400mm F4.5-5.6L for wildlife shooting
oh and don't forget to practice ahead of time, as much as you can (both taking pictures with it and then post-processing the pictures)! I rented a 100-400 for a trip to Yellowstone a year ago, and got some great pictures and loved them enough to buy a copy of the lens for myself, but I didn't always nail the exposure or the framing and didn't always have the shutter speed high enough. After more practice, my photos with it are much better, and I wish I had known then what I know now.

comment Canon extender 2x III with 70-200mm F4L vs 100-400mm F4.5-5.6L for wildlife shooting
It focuses just fine for me, but like I said I can't compare to the 70-200.

comment Canon extender 2x III with 70-200mm F4L vs 100-400mm F4.5-5.6L for wildlife shooting
I have a 100-400 and 30D and I'm perfectly happy with the combination, though I've never used the 70-200 so can't compare to that.

comment Why do cameras put photos in multiple folders on a memory card?
I'd guess a firmware bug? If I delete the DCIM folder, my Canon 30D will put one picture (numbered correctly, at least) in 100CANON/ then resume putting pictures in 103CANON where they belong.

comment Suggestions for a passport collage
"Creative ideas" are more-or-less out of scope for this site. For a "how to with Gimp," if you want to use just parts of each image, that's been asked at photo.stackexchange.com/questions/21504/… .

comment Tips for capturing fast-moving rally cars in low light?
You don't necessarily want to freeze the cars. Panning may provide better results; a too-fast shutter speed will make the cars look like they're parked, not moving quickly. Also, look at photo.stackexchange.com/questions/12839/… for more advice.

comment Why are there white dots on my night time photo?
@nwcs but there are no light sources in the image posted on that lensrentals blog post. Take a picture of a streetlight at night with the same lens and you will definitely see the cracks (they'd act like a star filter in front of the lens). Sprinkle a few water droplets on your lens and take some pictures of bright things, and you'll see the water droplets, like this water spray on my lens: i.stack.imgur.com/zyMLd.jpg
