: Is there an equivalent to aperture to look for in digital cameras? My current digital camera doesn't have what would have been in 35mm days a large aperture.. What to look for when concerned with action, or low light other than flash?.. Thanks Chuck (in SC) Most digitals list their apertures with the lens specs, though some of the smaller point-n-shoots don't display them noticeably, and you have to search for them in the manuals/literature. Usually, look for the notation "1:4-5.6" for the aperture, which would translate to f4 at the short end of the zoom range, f5.6 at the longest. These would be maximum apertures. Many of the smaller cameras cannot manage an aperture smaller than f8 For the most part, the smaller the lens, the less the performance. Even with small sensors, the idea is that you're collecting a lot of light to produce f2.8, so the lens surface has to be big in relation to the sensor. http://www.dpreview.com/ is one of the most consistent and comprehensive sites for camera specs and performance, and always provide aperture range. As for finding decent DSLRs, check out http://www.keh.com/onlinestore/home.aspx . Their condition ratings are usually *under*stated, since their used equipment is often in excellent condition. One of the leaders in used equipment in the US, very dependable, very professional. Good luck! - Al. -- To reply, insert dash in address to separate G and I in the domain |
