I am looking for a 70-300 Macro.
Should I wait for the new DG version or can go for old APO lens?
(At present DG is not available in India)
Thank you friends.
With love
Rudra :o) |

Hopefully, I can let you know about the quality of the DG version within a few hours, as I am presently awaiting delivery of this lens.

I have never actually used any of the dozens of versions of this lens, so I'll have no baseline for comparison. But I will know in about 20 minutes whether or not I like it :) |

I beleive the DG version reduces chromatic aperation (AKA purple fringing) and costs about $20US more. I'd hold out.

I too should know about the DG version by tomorrow. I had been looking for a long time and have seen photo's from both and never noticed a difference, but I still choose to get the newer DG rather than non DG. I have ordered a 50 - 500 Bigma DG and hope to have more details soon

check out this link on the differences between the new old versions. You have to sort through them as he test LOTS of lenses, But he does pit the old against the new 70-300 in both CA and sharpness test and varying apertures.
//210.251.243.169/~maro/lens_test.html
You have to scroll down a bit on the page for the 70-300 tests.
My impressions on the DG version (from his tests and other examples) is that there is a moderate CA correction--always a welcome attribute, and maybe a bit of improved sharpness on the long end. The long end of this lens above 200mm is almost always reported to be soft, regardless of how well the rest of the lens performs.

Well I have the 70-300 DG in my hands now (it arrived just as was leaving for work this afternoon, of course) and have only made a few quick shots around that house, but I think its safe to say that this is one helluva lens. Soft at 300mm? Hmm, only if you can't keep it steady... which ain't easy. I locked mine onto a tripod and used a cable release and MLU, resulting macro images are as sharp as a tack.
I won't know for sure until tomorrow when I check it in the daylight, but right now its looking like an exceptional buy.

I have the non-DG version and have no sharpness issues at all, at any length. Holding it steady enough is the issue i think. I try to run 1/500 or more abover 200.
the only issue i have, and i know it's me, is getting the focus exactly where i want it at 300mm, like trying to get the focus on the bird, not the roof or tree. after some testing, it is my, NOT the camera or lens at issue. Hence my upping the ISO now to get more DOF and more shutter speed.

Verdict is final on the DG version, it's a darn fine zoom lens. You should know that I am not a fan a zooms. Many zooms tend to be unsharp when used wide-open, and/or sacrafice some sharpness on one end or the other, not to mention the often nasty bokeh. Bleh!
Then, once you factor in the usual hassles of sample to sample variation worries--will I get good one?? or a lemon?--and the "what if my one lens that does it all gets broken when I'm in the field?" issue, then you have a good idea why I avoid zooms.
But, technology has made them so much better these days... Sharp across the range, good bokeh (if not great, like the Tamron 28-75) and so small and convenient, that I can't help but buy into the good ones. |
