Hello, I bought a horseman 45FA that has limited bellow length(249mm front only,272 max with back drawn).In the horseman catalogue, there is a 2 x LF teleconverter available for the sironar 150 lens that I happens to own too.Any one has any experience with teleconverters on LF lenses?especially with regards to the quality of the eventual image (like all converters,I know it will affect my 150mm lens by 2 stops)Also, will the converter affect the image circle?
Secondly,if getting a teleconverter is not a good idea then which are the 300mm lenses currently available that do not require a bellow draw of 300mm at least?And among them, which one is reputedly the best?
Lastly,I am also interested to do macro.As I have limited bellows, the only focal length for me to do 1:1 macro would be a 120mm macro lens.Any suggestions & recommendations?
Thanks in advance!
