Well, Asad got the same response you got, so far: "try something else", "look at somebodies work-not mine" and "what kind of bee is that?" In short bupkiss!
I've got the lens you inquire about. I've actually used it for both macro work and telephoto efforts. It works just fine; in all likelihood it's capabilities far exceed my needs.
If you had asked about build quality, I'd say excellent. Want to know about weight? Heavy. Need info about usability? Limited, it's heavy, specialized and big. I take it when I know I'll need it-otherwise it sits on a shelf.
Ahhh, but you asked about the highly specialized stuff: CA, Flare and (I assume) similar technical stuff. Soooo, this next part is going to come across as condescending, maybe a bit belittling---I don't mean it to be, but I don't know your qualifications to actually digest info about CA or flare or etc. and, well, the answers you think you are seeking don't really have much real meaning for the typical photographer.
Here's why:
To determine CA or flare specialized technique and equipment is required-outside the realm of the average photographers budget or interest. But a single condition is common to all such 'testing': the camera is going to be subject to conditions
where it should fail. And not just a little hiccup failure; a full blown meltdown or eruption is sought! And then the experimenter/engineer/scientist (not the photographer on a budget) will compare how well one camera/lens failed with respect to another camera/lens' failure.
Well that's certainly information every photographer needs!
But hold the phone! Do you know how to cause CA or flare? I do; and that info could be had for the price of a good book or some friendly conversation--see, I'm not all bad. And If you knew how to cause such calamities, could you possibly avoid them? I can. And if they cannot be avoided, could the be corrected; could they be fixed in post processing? Mostly!
So, it's big, it's heavy, it has the potential of making great images (YMMV). I don't care about the Tamron because I bought the Sigma (it fits well in the bag with all my other Sigmas macro line of lenses) and that broke the budget anyway. Probably, it will do the same to and for you.
And by the way, what kind of bee is that anyway?
Originally posted by mikeatnite Does anyone have experience with this lens they can share? IQ, resistance to CA/flare, etc? I am thinking about a longer macro than the DFA100 and would appreciate any info anyone can share on this particular lens. Thanks!
Whoops! Just saw an identical request from Asad_Masede a few threads down. Sorry for the repeat!
