CV15 vs CV21 comparison anyone?

Anyone have both the CV21 and CV15 and has done a direct side-by-side comparison of the two lenses on a film camera? I'd like to get a better idea of how their field of view, vignetting and distortion actually compare to each other.

 

I'm trying to decide which of these two i should order (probably from Robert White, in fact) - but in spite of trawling every forum and review site, and flickr and so on, i still haven't found a simple side-by-side comparison (and yes i have read Sean Reid's separate reviews of the lenses - excellent as always).

 

Ideally i'd just like some pretty objective shots of say a landscape, townscape and/or street scene shot with the lenses from the same location.

 

Strange that lens-manufacturers don't do this simple thing anymore - i remember (probably still have somewhere), a brochure from Zeiss in the 70s or 80s that simply shot the exact same scene with all of their lenses: gave an excellent overview of the differences in the range.

 

In any case, please note that the shots shouldn't be on a digital - which gives a totally different look and fov - but on a film camera.

 

Thanks!

For the C.V. Super wide Heliar 4,5/15mm I can sent you a picture made on the M7. For the 21mm you're pointing on the new C.V. 4,0/21mm VM-P lens suitable for the new Bessa R4 A/M?

It's brand new so I doubt there is much info on it already.

 

By the way, this is my version of the 15mm, including a 72mm filter adapter.

Thanks Robert - nice adaptation of the filter-holder you have there btw! ;-)

 

I've looked at quite a few isolated examples of each of the lenses' output now (i actually don't think that the L-mount release of the 21 is so different from its previous incarnation - correct me anyone, if that's wrong), but what i'm aiming to see is some simple side-by-side evaluation.

Subject matter or color/b&w doesn't really matter - what's interesting is some sort of direct way of comparing the output of the lenses to make a simple subjective judgement of which is preferable.

 

Thanks again!

 

(Looking through your photostream i'm thinking that i'm really glad i didn't have schoolteachers that look like the ones from your town - would've learned even less!)
