ELPRO for 50mm Summilux and 90mm Apo-Summicron!

was looking into my filters and I realized I have a Schneider Kreuznach B+W NL-2 close up filter. out of curiosity I hooked it up to 50Lux asph and 90apo WOW the results are incredible!

 

I'm sure the better solution is always an extension but NLs work really good and there is no need to take the lens off.

No, for non-macro lenses, close-up lenses are always a better solution than extension tubes (with the possible exception of long telephoto lenses).

Actually I'm waiting for novoflex extensions to do a comparison.

 

I usually do macros with 100 AME but these closeup filters are good for portraits when one needs just a little bit closer. +4 close-ups usually distort the image corners while extension don't affect.

I see B+W comes in different magnification values. What would you use with a 75mm lens?

Is following pretty much true? Close-up lenses – Close-up and macro photography for entomologists Especially the part with wide apertures.

 

I currently own OUFRO, and not sure whether to try with a close up. I'd use it with 75mm lens, maybe 135mm and EVF.

What would you use with a 75 mm lens?

For M lenses with a minimum focus distance of 0.7 m: +1.5 dpt; with a minimum focus distance of 1 m: +1 dpt. With higher strengths there will be a gap between what you can focus at w/ and w/o close-up lens. Add more (stronger) lenses to your bag as required, but the lowest strength always is the most important and most versatile.

 

 

Is following pretty much true?

No, it's not.

 

The strength of the close-up lens required does not depend on the main lens' focal length or on the camera's film or sensor format but on the minimum focus distance (if you want to extend the main lens' working range gapless) or on the distance you want or need to shoot at (if you want to achieve a certain magnification).

 

Close-up lenses are corrected for optical aberrations ... of course (as with any lens) to varying degrees, and never perfectly. More expensive close-up lenses usually are better than cheap ones.

 

High-quality, double-element close-up lenses, used within their intended working range on a good main lens, do match dedicated macro lenses at the same magnification. However the latter have wider working ranges and are more comfortable to use.
