nice diffuser at a reasonable
The diffuser ground glass plate (120 grit, 25x25mm) is free of scratches and nicks and doesn't have any visible variation in grit across the surface. I placed it across a photodetector to help homogenize the light received from a group of LEDs. Works ok. The diffuser reduces the light power level by about 28%.

Has all the wide angle and zoom that i need
1 of 1 found this helpful I usually carry two camera bodies and switch around three or four different lenses. This lens is lightweight and has all the wide angle and zoom that I need. Plus and this is a big plus, the aperture is larger at 62mm compared with the 58. Sure for the 180mm but it helps a lot for the darker environments using a typical 45mm setting. The internal lens elements look clear as are the pictures. The mechanism feels smooth - no grit, no free play. Very nice lens - wish I had purchased it years ago.
