Revuenon 55mm f1.2 Initial Impressions

I just bought a Revuenon 55mm f1.2 from a fellow board member I did some preliminary shots this weekend.
If you are looking for a lens that is super sharp wide open, this isn't the lens for you. But if you want a lens that gives a real painterly look, with the smoothest creamiest bokeh around, give this lens a look I already have a FA 50mm f1.7 which is really sharp, so I didn't want another one.
I have a feeling that this lens wouldn't look great on MTF charts, but it does have that certain soft, pretty rendition that gives you a dream like feel. Is that what some members mean by "pixie dust"? LOL
Anyway, I think I am in love
Only drawback with the lens is it has a long minimum focusing distance. I have some extension tubes I will play around with to see if I can get a bit closer.
Also, and this isnt lens related, the K-5's stock focusing screen is definitely not up to the challenge of a f1.2 aperture. I was using LV plus magnification. Here comes the EE-S focusing screen

Hi if you like photographing close ups maybe a 50mm macro lens because you said your new lens doesn`t focus close enough? Ok, I just noticed that you have the 100mm macro lens. I guess you were just testing your new Revuenon 55mm F1.2 lens ? Nice and dreamy creamy effect. Too bad Pentax never made an auto focus 50mm F1.2 lens and for that matter stopped making the Pentax 50mm F1.2 lenses all together.

Wasn't the A 50/1.2 still available new in some markets recently?

Are you the new owner of kenafein's Revuenon? I have the Cosina branded version and it is as sharp as it needs to be wide open - but so little will be in focus at that aperture that people will call results soft, but that is just what thin DOF looks like.





I have not tried it for flowers yet, but for low light scenarios, this lens is excellent. You should also make sure to use a hood with it, otherwise flare and reflections will affect the resolution, especially when using it wide open. A CPL might help to cut reflections on flowers - the loss of stop shouldn't matter when you use it wide open.

You have a great lens there. You should also try it at other apertures - I like its rendering at f/2.8 for people shots.

You are correct, I misspoke when I implied that it may be soft. The OOF areas just dominate the in-focus areas and just give that appearance

Thanks for the tips...i have never thought to use a CPL for flowers, but that does make sense

Wonderful lens. I almost got it myself from kenafein, but decided it was too much money for a lens I wouldn't be able to focus.
So, instead, I ordered a proper focusing screen and will practice with my 1.4 until I learn to get it right and then look for another one.
I am in love with it, and I didn't even have a first date yet.

Maybe is a copy issue. Mine copy is sharp wide open. Nowhere near soft. I have F 50/1.7, and to be honest, I don't se any real difference in sharpness, of those two lenses. maybe I have a softer F 50 lens who knows.

Laurentiu, do you have a hood recommendation for this lens?

I have found a round metal screw-in hood to be a good match for this lens.

Personally, I use this one on my Cosina version, with a 58-62 step-up ring. Works great, with no perceptible vignetting despite being a hood intended for tele lenses. (55mm is tele, sure, but not by much!)

And because the hood comes with a cap that fits the outside of the hood, I keep it on all the time. It protects that giant glass eyeball on the front of the lens quite nicely.

Interesting...is the bottom meant to flex?
Thanks for the info

+1 for the hoods that heavystar sells. Very sturdy and they match black lenses very nicely. I use a 58mm TELE one with the Cosina 55/1.2.

oh right..... I got the "normal" lens length version one as I thought the tele version might be too long even with APS-C sensor.
Looking at the size of the DA*55's hood it should be obvious.
Even so it does help though.
