Now that I have this wonderful new machine and not stressing over
developing costs I would like to try my hand at these macro shots I
am seeing and just falling in love with. If I understand right I
need a macro lens for this type of shooting. Any suggestions?
First of all, it's not ALWAYS the case that you need a "macro"
lens. Some general-purpose lenses are capable of focusing pretty
close, and might be sufficient for some subjects. Assuming that's
not what you're talking about, and that you really want to get very
close to some very small things, here goes:
There are a number of options, each suited to a different price
point and purpose. For starters, some consumer zoom lenses have
macro features (such as Nikon's 28-105D, for about ~$300 USD).
These lenses don't have the best macro performance, but are often
functional enough to start your education in macro photography, and
you have the added benefit of a versatile zoom lens for relatively
little money. Prime macro lenses are the next step up. They cost
more, don't have the versatility of the zooms in terms of focal
length, but offer better macro performance (up to 1:1) and are
often faster and sharper than the zooms. They are often very good
lenses, all around, so if you use their particular focal length for
non-macro work, you can get a lot of general-purpose service out of
them. Additionally, there are macro attachments and converters
available for some lens types that are threaded and used like
filters with lenses you already own. Finally, there are bellows
attachments that allow for extremely close focusing with standard
lenses (which are usually attached reversed).
As with all things photographic, you can get in at the lower end
without spending a ton, or you can spend a lot of money up front
for equipment that you'll never have to contemplate replacing.
Without knowing what level you're at or what you'll be using the
results for, my wild-@ss guess would be that a zoom with a macro
feature or a prime macro lens would probably be the best bet to get
you started. If you really get into it and decide to invest more
cash in macro-specific equipment, you can always make that call
down the road.
