As stated, macro lenses and lenses set up to be used for macro work have a very shallow depth of field. That's the issue you're facing here. Focus stacking is one method that helps this problem.

Hello Hedgehogs
I've recently upgraded from my 18-55mm to a Tamron 90mm macro lens. Loving it in its entirety but there's something wrong with how I'm taking photographs that's preventing my photos from being sharp and I'd like to correct that. The problem is that I don't know what I'm doing wrong. I'm still new to this.
I have this lens.
I use it on either a Canon 1Ds Mark III or a 1D Mark III.
It works great for me.
Tripods are where its at for Macro.
Even the tiniest shake will destroy sharpness.
It's even more pronounced when you are inches away from your subject.
Another though is, you lens may be out of calibration.
It could be front or back focusing.
I do more closeup shots than true macro, I will never chase bugs.
So my shots tend to be a couple feet away or more, then I crop down to what I like.
Don't give up, keep trying different f/stops. Check the calibration. Use a tripod.
It's not film, pixels are free, shoot lots and lots then shoot some more.
There is a learning cruve to this lens.

thank you for the explanation! But I know. I understand depth of field. My concern is with the sharpness of what is in focus. I feel as if it could be sharper. No matter what I do, it appears as if the in-focus parts of the image are a bit fuzzy.
The first was on a tripod, the others hand-held. Try redoing the others with a tripod?

You said it so much better than I did!!!
Levi.........I do a lot of macro.........I tried to read all the posts but I tend to get bleary eyed reading anything on the internet. If you want to improve your shots.......use a flash. When you shoot macro lighting becomes critical as you have serious light fall off and when you hand hold.......no matter how steady you are, you will have camera shake but using a flash will "freeze" the image and provide you with a sharper image. Using a flash will allow you to drop ISO to a lower setting(less chance of noise), to use a smaller aperture(f/11-16 works best for me) for greater DOF and faster shutter speed, though it is not that important when using a flash(you also may be restricted because of sync speed).
Lookup Mike Moats, his blog and classes
I did not see after a quick review of the responses where anyone suggested calibrating your lens. If you are unhappy with the sharpness of areas in focus, lens calibration may be called for. As I'm sure you are aware, newer Tamron lenses come with and optional "tap in console" that allows for micro lens calibration. I've not done it yet (although I do have it along with two Tamron lenses) but other UHH members say lens calibration with the tap in console works wonders.
