p.1 #3 · Old lenses for new SLR | |
Wide angle is one thing that you can't do well with vintage lenses on a modern crop-frame body. Because of the 1.6x effective focal length multiplier, even the best and widest older lenses turn into boring, non-wide focal lengths. If you want something similar to a 28mm on full-frame, you need an ~18mm lens on your DSLR (which severely limits your choices). The new generation of ultrawidewide zooms designed for crop-frame cameras are truly superb optics, and will let you get much wider (and sharper) pictures than are available from older lenses.
However, don't let that discourage you from using vintage lenses, of which there are many choices that are excellent for normal width, portrait, and macro (at a fraction of the cost of similar new optics). Ironically, lenses that fit Canon manual-focus cameras are about the only ones that you can't properly adapt to a Canon autofocus camera. Almost everything else (Nikon, Pentax screwmount, Olympus, Leica R, etc.) can be easily adapted with inexpensive, glassless adapters that preserve the full optical quality of the lens.
