Manual macro on the cheap.

Christine,

You got quite impressive magnification on that one. Reversing the 50 will not get you so high unless you try either tubes or a tc or maybe both.

Having just seen crazee horse's post then I am in between moon shots ( 400 + tcs ) action shots of insects ( probably reversed 50 ) and ultra closeups ( bellows tubes and anything to give magnification of small creatures ).

WPF just keeps you so busy.

Don this is with the old Tessar reversed stoped down to f11 the image is softer and cold looking. Not impressed.

I have been reading this thread with interest. I did use this technique some 30 years ago with my Pentax Spotmatic using a 200mm on the camera with a 50mm lens reversed. I still have them and the coupling ring.

However, the lenses that I now use have much larger diameters. I have the following
100-400mm diam 77mm
24-105mm diam 77mm
10-22mm diam 77mm
200mm diam 72mm
Do I have any hope of getting a suitable coupling ring?

So glad you have found the thread interesting Dave. I think you may have a job to get hold of a reversing ring for that size but you could do what I did. I have a p system 58mm adapter. I duck taped an old 50mm lens to the adapter it doesn't look very tidy as I had just taken the duck tape off and stuck it back to take photo.

Adapters are £3.99 from this firm for the 77mm ones

Thanks Christine, I may well give that a go.

Christine,

As it is an old lens I don't know about lens coatings. Image is sharp but lacks contrast. You have certainly captured a lot of detail that would be hard to see with the naked eye. Quite facinated by the feet.

I had a little play to increase contrast. I guess a touch of 81A filter in CS would reduce the cold feel.

Dave,

Be aware these adaptor rings are available in two outside diameters A = 77mm and P = 100mm.

For the 77mm filter thread you will need two rings from the P series. These can then be taped together to give a thread each side.

Somehow I knew in my rush to post that these rings came in various outside dimensions, I got it a bit wrong re series and dims, so this is a correction.

A series - 67mm
P series - 84mm
Z-Pro series - 100mm

I have found a 77mm thread P series and the land ( free flat area around the rim ) is 5mm. Probably a bit shy if mounting anything heavy. So for mounting 77mm threaded lenses I would look for Z-Pro adaptor rings. This would allow sufficient land for them to be drilled and screwed or popriveted together for ultimate security.

Many thanks for all the info Don. Later this week when I will have some time I will try my lenses out just hand held to see what may work and then investigate the means of attaching.
