These lenses are both very good but for tight spaces, you will want a wide-angle rather than telephoto, so between those two, the 24-70mm F/2.8L will be more suitable. Another point is that when lighting is low, you need slower shutter-speeds. Longer lenses though need faster shutter-speeds to be sharp, so again this favors the 24-70mm over the 70-200mm.


That effect was made famous in Hitchcock's Vertigo. It's called by various names: Hitchcock/Vertigo zoom, dolly zoom, reverse tracking shot. To achieve this effect, the camera zooms in or out, while the dolly (movable platform on rails) moves the camera towards or away from the subject to keep the subject the same size, while the background zooms in or ...


Constant aperture lenses have only advantages (except lenses which are total crap). There is no decrease of light when you zoom out and this is the reason photographers pay sometimes huge money to get such lenses.


You should also consider that you will never find constant aperture zoom lenses of the superzoom type (like Tamrons recently released 16-300mm for DX sensors). Sigmas 1.8 (crop format)/2.0 (full frame)-constant aperture lenses have zoom factors of less than 2, typical 2.8 zooms are less than triple zooms (24-70, 70-200, 200-500), F/4-zoom glass has typically ...


The difference is the minimum focusing distance each lens can use. This affects the lens' Reproduction Ratio which is also sometimes called the Maximum Magnification (MM) specification. Most lenses that are considered true macro lenses have a Reproduction Ratio of 1:1 (the MM is referred to as 1.00X). There are a few macro lenses with a 1:2 ratio (0.50X MM). ...


Macro mode on compacts usually zooms to the longest setting, and DSLR lenses with a macro setting will only allow to engage it when fully zoomed. Edit: this may not be true for all models as mentioned in the comments. When you turn on macro mode, the lens is able to focus closer than normally possible, and the AF system may be tweaked to prefer close ...
