One advantage to having a birthday in December is ability to group presents…
Have recently been trying to decide between 85d f1.4, 105dc f2.0 & 135dc f2.0--though a bit long.
Found many more discussions & reviews on the 85d f1.4, all of which gave it an unqualified rating of great (if there was one or two negatives, I don’t remember them) & extremely sharp, with excellent bokeh.
Found a more modest number of discussions & reviews (maybe 1/4th as many) on the 105dc f2.0. Most “rated” great, reasonably sharp, excellent bokeh… usually a bit more reserved in praise that what was given for 85f1.4. However, for each lens there were some who claimed to have had both, but now primarily use X.
One I found mentioned only minimally was that use of dc feature would impact sharpness…
Based on above I decided on 105dc. My planned uses were for some low/lower light limited indoor usage, outdoor portraits & general usage (similar to usage of 50mm indoors).
After the first few test shots I felt like I should take it right back. To be fair I decided to do some testing… What a pita!!!
Defocus control is labelled F 5.6 4 2.8 2 | 2 2.8 4 5.6 R
Per the directions use the F to blur the foreground, use the R to blur the rear.
My first test (on second lens tested) revealed that the “neutral” point was not as expected, but rather F 2.8. (This was actually case for both lenses tested.)
Picture below is to provide some perspective of sizes & distance…
First sample is of low light clarity.
Second is of foreground & background blur.
