I'd like to get a hood for my 50mm Summicron f/2 Type 2 - Rigid.
The obvious option seems to be the 12585 metal vented hood.
A few questions with this one:
Does the hood, which clips around the outside of the front (I think), interfere with filter use?
Is the hood a bit on the large side for what is a pleasantly small lens?
Is it possible to buy it with the cap that covers the reversed hood? Is it possible to buy that cap anywhere?
And that leads me to the alternative, the 12549/12550 Chrome/Black Elmar 50/2.8 39mm screw in hood.
This one /looks/ better to me but:
Is it effective enough as a hood for the Summicron Rigid?
Does it cause vignetting with a 39mm filter also in place?
What size is the front opening to allow a cap to also be used?
Or better yet - does the A42 slip on cap I already have fit right over it?
Thanks.
