Default Inverted lens...

I've been doing experiments with "low cost" macro equipment...

Reverted the 35-70mm lens in front of the 100-200mm lens ... as I have no inversion ring, I had to hold it by hand

It is almost impossible to focus on moving subjects ... DOF is incredibly small, but when it gets focus ... magnification is extraordinary (these photos are only slightly cropped to reframe) and I was very happy with the sharpness.

The ant did not stand still ... never been able to focus 100%

With still subjects is a lot easier to achieve focus... I'm happy with sharpness

G'day Rui

Yes mate - once you have the 2 lenses bolted together [sticky-tape??] then the magnification achieved can be awesome. Depth of field is often non-existant to very little, and as you are finding out - still subjects [dead maybe] are often best

ps- Years ago [film camera days] when I played with this stuff too, I used to tape a 5cm sq of kleenex tissue over the flash to soften the light as it was too bright & harsh for these extreme closeups - but I needed the light to use f22, f32 ...

Regards, Phil

Very nice job for hand held without a reverse ring!
