Honestly any of the current macro prime lenses on the market is a good choice:
Canon 60mm macro - 100mm macro - 100mm L macro - 180mm L macro
Sigma 50mm, 70mm, 105mm, 150mm, 180mm
Tokina 105mm
Tamron 60mm, 90mm, 180mm
Each one offers you top quality optics and the differences between them are mostly marginal optically speaking. The kinds of thing that you notice only in side by side unedited test shots. The best way is to consider :
Thanks for the reply. Its good to hear thoughts about this from others
1) Budget - what fits your costs
Well, since I am on government disability now... My budget is going to stay as low as possible... But I also want good quality. But I'm going to have to put money aside specifically for the lens either way. So I guess L glass is out of the question...
2) Features - AF, teleconverter compatibility, internal focusing etc... - consider the specific bonuses that each offers you
Honestly, I didn't realize you could get a macro lens that also offered tele-converter capability... But really I just want a good AF Macro lens... I guess if its in the same price range... I'd go for the TC as well.
3) Focal length - longer focal lengths give more working distance to work with; 90mm is the shortest most advise you start with if considering insects; otherwise any range will work (shorter just requires a bit more work for insects sometimes). Furthermore note that longer focal lengths render background areas more blurred than shorter ones, though its an extremes point (ie 50mm compared to 180mm)
After looking at the available choices, I'll probably go with the 90-105 range.... Now to sellect a brand... Two votes for Tamron 90mm so far...
4) What comes in the box (canon 100mm comes without lens hood or tripod collar for example).
This is less important to me, as I am more concerned with the lens... But obviously a decision making factor.
I've looked at the 100mm Canon, and ended up going with the Tamron 90mm, mainly due to cost.
Good to know... I will consider this.
...the AF on the Tamron is a non-issue for me...
Can you explain this? I have bad vision, and AF is important to me.
I've a friend who has the 100mm Canon and both our lenses give very good results when compared side by side. So, take Overread's advice (excellent as always), and figure out what your focal length needs are and what the other features you need. The longer the focal length, the more working distance you have (important for critters), but generally, the larger the lens is.
Thanks for the input. Its appreciated.
Frankly, I can't see why anyone who does macro WON'T have extension tubes available - they not very expensive, and they do give you options.
Hmmm... Another good poimt. But I think after debating it, that I'd prefer the 2.8 aperture. As I mentioned, I am on a pretty tight budget , and can't do both the lens and the tubes.
But, I haven't made a final choice yet... Thanks for the info.
