I've been fighting with both of my camera lenses. One is a Sigma 70-300mm which I can't get a good photo off of regardless of distance, zoom, subject matter or while using a tripod. It has a little "macro" switch on it, but I just don't find trying to shoot tiny insects from a minimum 9 feet away and always needing a tripod very useful. Maybe I'm just doing something wrong....

The other lens is a Canon 18-55mm and works fine generally. I would really like to get some closer macro shots though and it just can't zoom in close enough for me. I've looked at the lens converters, but what I'm wondering is how all of you get such lovely crisp photos of insects when they could fly off at any moment. Surely you can't be setting up a tripod everytime.....right?

What am I doing wrong? What lens should I be using? How do I get those fast nature shots?

Hi Welcome aboard.
Generally speaking any lens like the 70-300 Sigma that also does macro, also has more compromises build into it. Its not going to be a stellar performer, but you should still get good shots.
What is the minimum focus distance?
Also try sticking it in full auto with flash up and see if that helps, you may just need good shutter speed.


For macro shots prime lenses like the 60macro or 100 macro will be good as a portrait lens and good as a macro lens. My preference is for the 100 or 100+ as you can be back from the subject a bit.


Is it only macro photos that you have trouble with or with the Sigma in general. Have you tried using live view to focus, so see if that improves it.

in macro photography of insects you either set your tripod and wait for a bug to come or you have to be fast and hand held

the thing with macro photography is that the close you are smaller depth of field is so people often work at small apertures such as f11 or f13, and that doesn't let in much light even at noon, so they use flash (some version of it) to light up the scene, and by doing so eliminate any blur from moving and slow shutter speed, leaving them with the problem of exposure and focus, and with practice you will be able to come closer to bug without scaring it, and also faster to achieve perfect focus (try manual works best for me)

also don't expect doing any close macro work (such as gmazza in this secton of forum) without dedicated macro lens..

and if you can't afford a flash at this moment you could try using a plate for birthday cakes (plastic white thin...) to put it around the lens, and it will serve as somewhat ring flash together with your pop up flash
