Originally posted by Lowell Goudge I guess the question is, exactly what are you trying to achieve with the lens.
remember that the diopter is really 1/focal length, and with the close up attached, you modify the maximum focusing distance of the lens to be equal to the focal length of the close up lens. A 0.5 diopter therefore sets the maximum focusing distance to 2 meters.
A short answer to that is: I am trying to figure out ways to use the FA 85mm a bit more.
It is such a nice lens but because of the limited FOV on APS-C cameras, I don't find the focal length that useful. I really wish it were a 35 or 50mm
I was thinking about using extension tubes but have not tried it.
Maybe I'll just get a close up lens and use the 85mm as macro lens since I don't have any macro lens
I want to keep AF if possible, that's why I am thinking of close up lens instead of extension tube.
2 meters maximum focusing distance doesn't sound too bad. I don't need to get too close to the subject.
I am thinking about those few macro shots in a wedding situation such as the wedding ring etc. So I can basically put on the close up lens when required and take it off to take normal portraits.
Should I buy those cheap close up lens to play around with before getting the expensive ones?
Maybe the one with +1 diopter because they are easier to find compared to +.5
With higher magnification (such as +2 or +4) does it make the DOF thinner than +.5?
