Thanks for the replies.
If I used one, I always used the 1:4-5.6 as it was lighter and the filter ring does not rotate, but I nearly always used a 18-135 or 18-200
I changed from Canon to M 43 at the end of last year, and I have given away and sold nearly all my Canon gear. I have a 650D, a 550 and a 450D and a couple of other old ones left.
I kept the 650D, 10-18 lens, 55-250 IS lens and a 70-300 Tamron IS lens only because my daughter and 11 year old son, and another daughter and grand daughter in SA have Canons I sent them.
The reason then for me asking is not because I want to use on, but I want to send what is considered the best to SA, they are worth so little here they are not worth the effort of selling.
