Today I used the Mir-1b with a 12mm extension tube to see how it goes as a macro lens. The first thing I have to say is that even with my smallest extension tube you get really close with this lens. This is no problem if you want to take pictures of small flowers, they can not be bigger than 5 or 6 cm if you want to fill the frame but taking pictures of insect is more of a challenge because you have to get so close. The quality of the pictures is not bad but it is not as sharp as my dedicated macro lenses. I like the flower pictures, but even with f11 there is not mush in focus, as expected.
I bought a cheap reflector for my large flash on E-bay. It focuses the light straight forward or down if you want to. There are three reflective surfaces to choose from, i choose the gold one. It was sunny and with the shutter on 180/s and the lens closed down to f8.0 or f11 I didn’t need a flash but It provided some subtle light. I have to use it more but for 6 dollar you can’t go wrong.
The pictures are edited in Dark table, I did some extra sharpening and some levels but not much more.
