Hi Jostein,
For 4X magnification I usually use my bellows with an FA501.4 reverse
mounted. It works quite well.
With your 200/50 combination I take it you are adjusting the aperture on
the 200. You might want to try closing the 50 slightly too, it might help.

Gang,
Does anyone have a recommendation for lenses that can be stacked to give
approximately 4x ?
John Shaw warns in his book "closeups in nature" that not all combinations stack
well together, and between the lines I read that very few actually do.
I use an FA50/1.4 lens reversed in front of an A*200/4 macro. This combination
gives 4x magnification, but has some problems with low contrast and serious
problems at small apertures (refraction?).
When I look at photos taken at 4x by other photographers, I realise that there
are better optics around for the purpose.
I'd be interested to know if you have some experiences with moderate wide-angles
reversed on a bellows as well.
Cheers,
Jostein
