CV 21/4 Color-Skopar Opinions

do ya think a 21 is different enough from a 25 to warrant having one?

Though I haven't used the wider lenses as much on RF cameras as on SLRs, I find a very distinct difference between the 24 and 20 that I have. You have to remember that the millimeters don't add up to much difference but the field of view changes significantly. Someone above mentioned that the perspective is much more dramatic with a 21 than a 25, and I agree.

i'm thinking the same thing joe.

funny how, years ago when i had a 24 for some slr system, it just sat in the bag. i could not see wide. and now when i put the 90 on a camera i cannot see long.
this is gonna be fun.

Even with the rectangular hood? :bang:

Yep.

To set the rectangular hood on the skopar, you need first to dismantle the regular hood, which is a PITA. So, mine is always screwed to the lens. Honestly, I never shoot this babe without the rectangle hood (I bought both the same day and it was settled by the vendor).

But as already stated it is a great lens, you just have to know what you are doing (perhaps the flare issue is due to focal length and you may encounter the same behaviour with ZM or Leica, I do not know, I am just a poor amateur jerk...).

Just uploaded some CV 21/4 land/city scapes that I took when I had it. As you see my sample was quite resistant to flare (with rectangular hood), but with such a wide angle skies easily get "un-even" in color ...

When I said flare, the conditions were much more severe than those beautiful pictures. It is not that bad, just that, as ferider said, you have to be more aware as the FOV is quite big!
 
Great shots Roland. I particularly like the vertical composition of the helicopter.

Pstevenin, I appreciate the warning. I have decided to get the lens (with the rectangular hood). Now I'm just waiting to see whether Stephen Gandy can get it to me in time for my trip.
 
with the lens cap on i am guessing that even pressure is applied.
without the hood, uneven pressure is applied, the metal bends and it's hard to get off.

another trick is to grap the lip of the shade with 2 fingers and turn and it will come off easier, no pressure is applied to the side of the shade this way.
 
I've never had a problem taking the ring off my 21.

When getting stubborn filters off, I tend to press the filter into the palm of my hand and turn, that normally gets them off. But you get an itchy palm too.

Here are a few samples from the 21mm f/2.8 Biogon-G; don't know how similar this is to the Biogon ZM...
