Macro camera lens

I'm interested to see if anyone has suggestions for a good lens to start taking high-resolution, macro photos?

^^^^ I should've mentioned I have a canon t2i.

The Canon 100mm f/2.8 USM Macro is probably your best bet. It's about $550. It's focal length on your camera will equal around 160mm because of the crop sensor allowing you to get really close up and personal with everything you're shooting.

If $550 is too much, you can look into the Canon 50mm f/2.5 Macro ($279) or the Canon 60mm f/2.8 USM Macro ($430).

Thanks man--appreciate the links too.

Do you know of any photographers who focus on that type of work?

There are a lot of photographers who do mostly macro photography. Many are just hobbyist photographers who love setting up macro shots. The few that are professional generally do macro work on the side for fun and shoot weddings, portraits, and the like for their cash flow. Some also teach workshops on macro photography for their cash flow as well.

A few photographers I follow are:
Nadav Bagim (Goes by AimishBoy)
Markus Reugels (Goes by Maianer)
Nordin Seruyan
Dusan Beno (AMAZING work)

Aside from photographers like that, you have the people who go really crazy into the macro genre and do what is called photomicrography. This is using electron microscopes and whatnot as lenses and capturing crazy detail and information.

Those were all incredible. Thanks man, you've been a great help.

I've got the Canon 60mm f2.8 and its a good lens but you have to get really close with your camera. The advantage of the 100mm is that it will let you sit further away and not bother your subject matter as much i.e. insects and what not.

oh yeah, a good tripod and remote trigger are also very helpful for macro stuff

Great advice by kuahiwi. A tripod and remote are great additions. I forgot to mention in an earlier post that you can also get extension tubes. These will essentially turn any lens you have into a macro lens and or help you get even closer with a macro lens. Kenko tubes are about $200.
