Originally posted by sany Thanks All for helping my informed purchasing, I got this lens now - although I can see slight dust particles in the front element and minimal marks on the front element which looks like some kind of coating chip offs but can't see any thing of those in the captured images so I went ahead with the purchase.
This lens is a LD version and not a Di. I have attached here one (i have cropped it a little to see the detail) of my first few shots as a trial.
Question: Since this is my second lens and first lens that has an aperture ring, my question is i am able set aperture size from the camera body. But when i try to change the aperture size from the ring itself I was expecting the aperture size displayed on the LCD screen also to change accordingly but it didn't, is this something I am not supposed to expect? if so how and when the aperture ring can be useful. Thanks once again.
That is exactly what is supposed to happen. With our modern cameras, there is no real good reason to use the Aperture ring with one exception if the lens is an A type lens. The exception is, if you are always hitting the dial and accidentally changing the aperture (as I do sometimes), the aperture ring use will cure that. Unless you're carrying a pencil and paper (old school EXIF), what you will lose in that proposition is the f stop information.
