The first one is pretty good too with bags of action.

I have just acquired a Schneider-Kreuznach Radionar from some time back in the 40s or 50s. Given its focal length I wondered if it would be good for macro? It was full of fungus but is easily dissassembled and it cleaned up very well. I cobbled up a 32mm > M42 mount for it. The Prontor shutter is so much scrap but I don't need that. The iris is beautifully smooth and the image is exceptionally bright when wide open and still good at f8.

It is presently on the K5, on the end of the full 3-piece Asahi M42 extension tube set with a further adjustable double helicoid mounted in the middle for focussing. I forgot to photograph it but will do so tomorrow. It's a learning curve but the results are amazing. The working distance for these shots is a full 30inches and they are all cropped to the subject with magnifications up to 150% !

As an example of the crops that have been made, here is the full original and cropped subject

Most at ISO200 and f8. Even though the front element is well exposed it appears quite resistant to flare but a hood is the next project.
Comment welcomed ....

I can never understand the need for the latest gadgetry and even less the way "film lenses" get put down as yesterday's technology. If it isn't all automated and spoon fed onto the card like greased lightning it gets decried as not being up to the job. OK, so I had to input the parameters manually, sneak up close to the thing and, horror of horror, focus it by hand ! But what's wrong with this? A Canikon in machine gun mode would have scared it off instantly!

K5 and an 'A' series 50mm macro.

Isn't it wonderful how they always use the same route? These are a lot better than good!

Changing the subject slightly, one other classic 3D stereo promotion was by Weetabix who put paired sets of images in their cereal packs. You had to purchase the bright red folding viewer (for half a crown I seem to recall). For a freebe they were fantastic quality.

Lens to kill for ... and you can see why!

Depends on the aperture setting. If you've got it near open then it can't shut down and there is little to see. Set it to 6.3 and smaller and you will certainly see a change. The image in the viewfinder darkens somewhat too!
