Welcome. The more the merrier.
Yes that does help cos it tells me a #1 is for a 28mm lense. I've searched high and low for this info on the web. At the moment I would also like to know which hood is for a 35mm lense. Down the line I may need others.
Currently I have an Aria and a 167MT. I was thinking of getting an S2 but have decided that an RTSIII will be the next. Primarily for the mirror lock up when doing landscape work.
Do you know if the RTSII has mirror lock up as that would be a cheaper option.
Currently I have a 28mm AE, 50mm MM 1.7, 85mm MM 1.4, 135mm MM 2.8, 35-70 3.4 Vario and 28-85 Vario. Next lense will be a 35mm 1.4 but they are very pricey so will have to wait.
