What lens have you got on that?
I hate talking about gear when I am using it. As a long suffering wedding photographer I used to dread the approach of the serious looking old gentleman with a scuffed brown leather cased, 50’s vintage, camera round his neck. Usually he had just been fiddling with for at least ten minutes to take one photograph of his rather overweight, and definitely bored, wife in her best hat. I knew the inevitable question was coming.
‘What sort of lens have you got on that?’
‘That’ was usually a 6×4.5 Bronica film camera. We used to use medium format cameras because no one believed you were a pro with a 35mm SLR
My reply was often a completely genuine, ‘I don’t know.’
I could see him debating as to whether to rush off and exclaim to the bride that she had booked a complete idiot to take her wedding pictures, or whether to tell me not to be such a sarcastic bugger.
