Scattered Thoughts . . .

Yesterday, I got to thinking about macro photos.  These close-up photos require some special equipment so I was wondering if I could patch something together to allow me to do some macro photography. Back a couple of weeks ago, I did try adding a macro converter lens to the front end of a couple of my old Pentax 645 lenses.  That worked "okay" but I did need to crop the photos a bit to eliminate hard vignetting.  It worked but it wasn't ideal. Yesterday, I remembered that one of the lenses I have been using on this Fuji GFX medium format camera is a Pentacon 50mm lens with a m42 mount.  The m42 mount is really just m42 threads.  It just so happens that I already use m42 fittings for my astronomy gear so I had a few m42 extension tubes on hand already.  Adding an extension tube allows me to get far closer to the object I'm photographing.   Every lens has a minimum focus distance...  if you try to get closer than this minimum focus distance, th...

I haven't done any macro photography in a very long time...  perhaps a couple of decades...  so I tested some of my photography gear over the past few days to see what works best for macro photography when using some of my newer gear. Although I have quite a bit of photography gear, I actually don't have any macro lenses.  Macro lenses allow you to get closer to your subject due to the closer minimum focusing distances that macro lenses provide.  I do, however, have some extension tubes which also can shrink the minimum focus distance which allows me to focus on objects that are much closer to the lens than without an extension tube.   Getting closer makes your subject appear larger in the frame (obvious, I know, but I had to mention it).  Lenses oftentimes only allow you to get as close as three feet or so.  With some lenses, you can only get as close as ten feet.  It is difficult to get a close-up view at those distances so adding an exten...
