So I bought a Kiron 105mm f2.8 1:1 lens recently to be used with my Sony a6000. I know that the difference between a 50mm macro and a 100mm macro is how close you can get to your subject, that is with 100mm you can back up a little bit and still get the same magnification.
But when I tried getting some pics with my Kiron lens at 1:1 setting I still have to get pretty close to the subject (probably about 15cm or so from the front end of the lens) to get it in focus. Although I have heard people say 100mm macro is good for insect/bug photography as you can get pics without scaring them off, my working distance is still pretty small at 1:1, which probably isn't a practical distance.
Can someone explain what I'm not getting here? At 1:1 magnification ratio is there a real difference in using a 50mm or a 100mm in terms of the working distance?
