Looking at taking close ups of flowers, insects etc.Hi reg g
What will you be using it for ??.
reg, I have a Canon 70D and recently brought the Sigma 105macro lens. I have used it and it is nice and sharp, but not given it a good exercising yet. I borrowed my daughters before I made the purchase and she got fed up with me wanting it (don't know why as I bought it for her). My uses will be flowers, butterflies and creative shots. I am still getting used to it but. That is purely user ignorance but I am getting there.
best thing to do is try a couple out if you are close enough to a shop or maybe know someone with a macro lens.
Enjoy your searching.
Thanks to all for the replies and advice. The Sigma 105 does look good, especially as it has image stabilisation whereas the Canon doesn't (I think). I was a little concerned that on my 70D it would give an effective length of around 160mm but is this really a concern for macro photography? I think I will have to go into my local store and see if I can try both lenses out.
The 100mm macro is fine on an aps-c camera like the 70D. It lets you be a little farther away than somehting like a 60mm would. The Canon 100mm L macro does have stabilisation but is a lot more expensive. From what I've read the Sigma 105mm OS is very good (I have the Canon 60mm and 100L but haven't used the sigma).
