Don't we all dream of having a 1DsII?

No, my dream is a 1DIII because I live in the high ISO range and a clean ISO6400 is just what the doctor ordered.

Canon makes TV lenses with green rings... I'm not sure if they are DO, but they are compact for tv camera lenses.

Even so, rather harsh statement. Do you have any facts to substantiate this with?

Kind regards, Wim

Some things just don't need to be proven beyond all reasonable doubt Wim, his statement (while harsh) is one of them.

I don't know if I'm included in "we" but I think they do, i think like all over technologies, it just needs time so that new methods can make development and construction costs go down, and the optical qualities can be improved.

Well, I respectfully disagree. The people I know who own a dslr, if they do have a grip for their dslr, have it for very specific reasons, or they don't have one.

Kind regards, Wim

I am afraid I agree with Ed. IOW, no. It iS a very expensive technology, which only provides a small benefit with regard to build length and weight, and has some very specific disadvantages, which weight rather heavily against it.

In the film era, they would have stood a chance. In the pixelpeep era we live in now, not. Of course, that's just my opinion :).

Kind regards, Wim

How about open statements made on POTN by users who declare that it makes their 5D look like a 1DsII, at least one within the past week or two!

Whee, thread derailing. I can't imagining dropping money on a grip for aesthetic and ego reasons. I mostly wanted to be able to use rechargeable AAs, like everything else I use (including the flash).

No. I could never balance the cost/performance in my mind, so unless the cost falls a great deal to straddle the line between L and non-L...........

There's no DO in those lenses - they're just green.
