What is Kenko Teleplus 300 "DG"?

I have a Kenko 1.4x TC and it says 300. Is this a DG? I can't find anywhere that says there is both a DG and a non-DG. Thanks.

DG is a Sigma name for their new coatings.

Mine says "DG" on it. The DG is much like Sigma's DG designation...it just means that they have added extra lens coatings to minimize flare and such for digital cameras. As far as sharpness and bokeh go, there should be little or no difference between the two. For flare and CA control, the DG may be a bit better.

For Kenko Pro TC-talk:

DG = black
non-DG = white

I have both and they are optically identical.

And the Tamron "SP" are identical to the Kenko Pro non-DG.

Speaking of Kenko and Sigma...

Will the Kenko 300 1.4x play nice with the Sigma 70-200mm variety lenses?

Yes. They play very nicely together with very little arguing or fighting. Nice!

Great. Thanks.

I've been considering trying one of the Sigma 70-200 2.8 lenses in place of my 70-200 f/4 IS lens. I know, I'm mad, since I love the Canon... but I'm curious about how f/2.8 would work vs. f/4 with little kids outdoor action & sports shots.

Of all the 70-200 lenses out there, the F4 IS is probably the sharpest of the lot. If you need f2.8, then you need f2.8. But that F4 IS is a dandy.

In full, reading around the circumference mine reads:

Thanks.
So there is no way a white one could be a DG, and vice versa?
If they are optically identical, would it be smarter to buy the cheaper one?

No. White is non-DG, black is DG (in the Kenko "Pro" model). I say get the one that matches your lens color. I have both, one of each.

Well, I don't really need f/2.8, since I always use this lens during the day in good light. I'm thinking about the Sigma only because I'd like the bokeh effect of f/2.8 vs. f/4.

LightRules, do you think a switch like this would be a mistake, based on my wants/needs?

From what it sounds like to me, I would recommend you sit pretty with your 7-2 f4 IS. Optically it's top-class and you will probably miss the weight-savings after a while if you move to the 7-2 f2.8 lens-class while finding that the f4 is plenty fast for day-time shooting. And frankly, the 7-2 lenses don't have the best bokeh anyway, be it f2.8 or f4. So IMHO, stay put.

Interesting. Thanks very much, I appreciate your input!
