Like title sais, I went out to play with my newest toy, Vivitar 2x macro focusing tele converter. I got it for 20€and it is interesting little device. It can serve as regular tele converter but also as macro converter. It has build in focusing helicod and can turn your regular 50mm lens into 100mm macro 1:1 lens. I use it with Canon 50 1.4 so it converts it to 100 2.8 1:1 macro.  As regular converter  it is nothing special, but for macro I find it quite good, especially when considering price. It is sharp enough and is easy to use. For 1:1 magnification you need to focus lens to closest distance and then use focus on converter to get to max magnification.  It is also possible to use all steps in between. These samples are all handheld, aperture on lens was set to f8 and I used built in flash as I left my Yongnuo at home. It is hard to handheld at 1:1 as doff is really thin but with practice it should get easier.

    • I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.
    • I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results. 
    • Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.
