Default Macro Lens Experiment

After using my DA* 300mm F4 to get some quasi macro shots last week I played around with some ideas at home. I tried the 300mm set to manual focus to see if the Catch In Focus would work with it. It did! I then tried using the 300mm with my AF 1.7X adapter. It worked with a small focus range that adjusted vey fast when the lens moved into position. I then tried the AF adapter with my Vivitar Series 1 80 180mm flat field Macro lens. It also worked.

Today I tried these set ups in the field. The first two photos were with the K5, DA* 300mm, AF Adapter combo. The third and fourth images were using the Vivitar, AF Adapter combo.

Hi Ed,

Very nice results!

I'm assuming that you used AF for these.

I've been using the 1.7x AFA and AF-C for even 1:1 or higher mag ratios for a while now. The very short focusing range (only a few mm at 1:1 or higher) of the AFA makes Auto Focus a practical technique for macro shooting for me, and just adds more to its value. An added benefit is the deeper DOF from the longer shooting distances that are possible because of the additional 1.7x magnification. The loss of 1.5 stops of light does make the use of flash almost mandatory, but I like to shoot macros handheld, so I'd be using a flash anyway. . .

I'll admit to being an unmitigated fan of the 1.7x AFA. I have one on my cameras more often than not.

Interesting to compare the two lenses with the AFA. I prefer the color/tone/contrast in the first two pictures more than the second two. The last one is so sharp though and it makes up for anything lost in contrast, something you could adjust with post processing. Both combinations look really, really good.
