El-Nikkor vs Pentax M macro test

I now have a reversing ring for both so I decided to do a quick test. I accidently bumped the camera so i had to re-adjust, but all things are pretty much equal.

Both at F/5.6 reversed on the end of my Pentax F 135mm @ F/2.8, and 20 images stacked each.

Just RAW conversion and stacked in combine ZM. The m 50mm had a lens "hood" (lens cap with a small hole in the middle) while the nikkor had nothing. I can't figure out a way to do this for the nikkor, but so far it seems to hold up fine without.

conclusion. The El nikkor 50mm F/2.8N cost me $20, and is better than my main staple the Pentax M 50mm F/1.7 (cost me $30). Looks like I got a new go-to lens

El Nikkor uses m39 leica thread mount, so you can make a "hood" from a m39 rear cap; there are different rear caps for m39 and some of them are pretty deep.

I'll look into it, thanks!

Nice, Yeatzee!
A myopic question: What differences do you see between the two results? Is it just sharpness or is the nikkor better for you in other ways, too?

microcontrast, sharpness, rendering, etc.

Big spender! I recently went all the way to US$17 for an Ernst Leitz Varob 50/3.5, but generally I avoid paying more than $10-15 for EL's. I got a set of four 75mm EL's (Wollensak, Vivitar, Schneider, Rodenstock) for US$10 combined/shipped so I feel justified in going cheap. [/me not ashamed of bragging]

Enlarging lenses on tubes - what a way to get a bang for the dollar.

I use them on Asahi Pentax Auto Bellows and really enjoy the El Nikkors and a few other brands written about at this link.

Well good luck getting an El-Nikkor 50mm F/2.8N on ebay for $20 these days!

For a Rodagon, that IS a decent deal. The four I mentioned aren't in that league:

* Vivitar-LU 75/3.5
* Rodenstock Omegaron 75/4.5
* Schneider Componar 75/4.5
* Wollensak Enlarging Raptar 75/4.5

But yes, some EL's really ARE four for a dime.
