Aquarium Photography Guide Part IV: LENSES | Reefs.com
Distance information- some lenses have it written on the barrel of the body, others like the Tokina in figure,7 have a see-thru window that informs you of the distance from the camera to the subject when manually focusing the lens. It is called in photography infinity focus and it basically means that when you turn your focus ring into that position you can make objects in far distance in relative focus (as much as your camera+lens allows). It is useful when shooting landscape photos and with smaller apertures (only if you focus manually of course, when lens is in autofocus mode, this ring locks and cannot be turned) This category of lenses often comes first with the purchase of new... Even the cheap, plastic lenses that most camera manufacturers offer for beginner deliver some good results. They can be divided to two sub-categories, telephoto zoom lenses (most popular 55-200mm and 70-300mm) and telephoto prime lenses (one focal length, for example the popular 300mm f/2. 8). Wide-angle lenses are those lenses that have shorter focal length that standard zoom lenses (usually lower than 15mm). Don’t let the really low price (Nikon 50mm f/1. 8 lens costs $220 at the time of writing this article) or sometimes plasticky feel deceive you- prime lenses are of great quality, because their design is simple, they have less elements and moving... It is widely accepted that Telephoto lenses are those that focal length exceeds the range of normal zoom lens (55mm is a good staring point for telephoto lens). As I mentioned in previous parts, prime lens is a type of lens that has fixed focal length, meaning no zooming capability (unless you consider your legs as a zooming device). With a standard zoom lens you are able to shoot a full tank shot of small to medium size aquarium as well as fish and coral colonies portraits. Telephoto lenses have their time when you are a bird-watcher or like to spy on your neighbors, but in fish tank reality they have little use. Some zoom lenses have only one number, for example f/2. 8 (see figure 5a)- that means no matter what focal length you are, the maximum aperture will stay at f/2. 8. Prime lenses are my favorite type of lenses for many reasons. The standard “kit” lens is in most cases a 18-55mm lens. Unfortunately, if you don’t have spare $7500&up for the like of Canon’s EF 300mm f/2. 8L IS II USM or something similar, you’re out of luck because consumer level telephoto lens cannot deliver the level of detail required to photograph small... Most wide-angle lenses slightly distort perspective making rooms appear bigger (that’s why real estate agents love them) and close objects appear farther away. They are useful to take full tank shots of large private and public aquariums or to highlight the whole fishroom. It is considered a standard lens because it doesn’t allow you to go very wide nor it can zoom very far. Some wide-angle lenses have a relatively small minimal focusing distance (a foot or less) making them even more tempting. 1m) so I have to be over three feet away to focus on the fish that is close to the glass....

After borrowing an on-stage judge's iPhone and installing it in the LifeProof case, the tuxedoed demonstrator dropped it, covered it in eggs and ketchup, and dunked it in a fish tank to clean it off. The phone emerged unscathed.
