I'd almost be willing to bet that his lens is lighter than my Canon 135/4 rf lens. Carry that brick around for awhile? Anyway, You should of talked to the man. You'll never know where that conversation would have led you. I was on my job making a delivery into the back room of a customer. I opened the door (there was no sign BTW) when a flash went off. I walked right into an ad shoot with my customer & a pro photographer. While preforming my job of pumping oil into the c's tank I struck up a conversation with the photographer. He was excited about my carrying a camera with me, I had my Zorki 2c & elmar 50 coll. in the truck. The owner of the store told me to go get it, so I did. I didn't shun him for using digital & he didn't shun me for my old film camera. He was also shooting with a fairly old med. format setup also. The best part to what I'm getting at is that he is big into getting photographers to showing their work in galleries and such, & while this is something I would like to achieve one day, if my work is ever deemed good enough, he gave me an invite. So it pays to not judge another's equipment, because were all accomplishing the same goal in taking photos.
