a) please (if you can) list down the entire designation of the lens - ie, all the alphabets and watnots of the complete lens' name. this will make searching on the CS engine much easier. better still if you can tag your posts with keywords.
Can we have a standard format because people can write it in different ways.
For example, AF50mm/1.8D or AF 50mm f/1.8D (with spaces) or even AF-D50/1.8. I think searching with these numbers could never give me what I was looking for.
Most of the time I'll drop the f and mm and have the focal length and aperture as an entire block. So I would write 35/1.8 or 18-200/3.5-5.6. Usually never put the letters because there doesn't seem to be a standard format (space or no space).
