Hehe....I wrote a similar query here last spring and got lots of assurances that the Geronar is a very decent performer. After using it exclusively for months, I came to appreciate its' strengths and weakness. However, recently I was complaining about it perhaps not being as sharp and...well....for want of a better word...dynamic as perhaps a 'better' lens. If you check that later thread, you'll read every responder pointing out that the 'fault' must lie elsewhere...it was almost certainly NOT the lens. Shortly thereafter, I made one of the most crisp and lovely images I've ever made (posted here in my personal gallery: Barnside and Vine.) with it. So....I've quit bitchin and come to really appreciate the strengths of the lens. I'm happy with it now....I guess I was just reacting to a lack of experience with any other lens to compare it to.
BTW, Eric Rose has an image in the Autumn issue of the UK Black and White magazine made with the 210 Geronar. Check it out. It's excellent!!
