What lenses do you have now? That might influence our recommendations.

How much are you willing to spend? That might influence our recommendations.

650 euros is more than enough for a good macro lens, but I too would suggest the Tamron 90mm macro as it's good quality at a reasonable price. Cheaper options are to use the Raynox closeup kits, but if you're keen on doing macro often, a dedicated macro might bring you more joy.

Looking at the picture, I would say you are right in thinking you'd get better images with a dedicated macro... at least in terms of CA/fringing.

$650 gives you a good range of choices. Bad macro lenses are virtually unheard of so choose one which feels comfortable and provides the focal length you need. I'd recommend between 90mm - 105mm. Feel free to go for an older model such as the Vivitar/Kiron/Lester Dine 105mm. You should be able to get one with the 'A' setting for $450USD (312 Euros) and lack of autofocus shoud not be a problem if you move the camera back and forth for fine tuning the focus.

The Tamron 90mm Macro is to bugs what the Hubble telescope is to galaxies--superbly splendid! 2 big thumbs up from this camp. BTW, the Tamron 17-50mm is a great choice for a walk-around lens, has great close focus capabilities, but let its big brother (Tamron 90mm) shoot the bugs. Here are some Milkweed beetles, just hanging out in their home. f9, 1/30th, ISO 320:

The Tamron 90mm comes out of the box as a one to one, but if you want more magnification you can get extension tubes--your call--but I would start with the lens as is, and work up from there.

That "certain macro flash" is called a ring flash--they are awesome!

Best!

As I wrote before... no such thing as a bad macro!

I have no experience with this lens, but the D FA is a full frame lens, so you can use it on your film/future full frame bodies. WR is a good choice for insects which live in wetter climates. Nice choice

I think you are going to be a very happy camper--stop writing, and start shooting. Best!

BTW, while obviously a real macro lens will do better than your +10 closeup lens - so would a better closeup lens. That's undoubtedly a poor quality single element lens that is just rife with CA. A good quality achromatic multi-element closeup lens like the Raynox 150 or 250 will produce *far* better results for under $50. Given your equipment, I'd recommend the Raynox 150 used in conjunction with the 50-200 for the best balance between image quality, magnification, and working distance. See the Raynox club thread inthis forum for some pretty incredible examples. If you still decide a macro lens is the way to go, tht's fine of course - I just don't want you to think it's your only viable option, because it definitely isn't.
