55/1.9 vs 55/1.7 is basically a tradeoff between sharpness and bokeh smootheness.
Both are great in my opinion.


Which has the better sharpness and which the smoothest bokeh?

55/1.9 is a bit sharper and 55/1.7 is a bit smoother.

I recently got version 1.9 and now I have all three instances. I will try to test all three in the near future.

My Auto 1, 8/55 (camera with the SR 1) rendering in the 1,9 way to me

Hard rendering like the st 1, 8/55

Version 1.9 - 1.7-sigma45 / 2.8. Someone said that this is a compromise between sharpness / contrast/ smoothness. I agree with that.

Very clearly for my eyes.

Minolta and his green Long.CA.

This is the great con of the MC 1,2/58 to my taste.

Thanks for sharing. Very informative

Wow, sharpness, contrast and bokeh better than I expected from the older 55/1.9. I'll have to put it on my list! It even seems to have a smooth OOF for more challenging backgrounds.

I would argue this backwards: quite a number of 55s were significantly smoother than their 50mm successors.

Yes, 55/1.9 is one of the smoothest fifties there is, bowing only before its own ancestor, 55/1.7.

Version 1.9 is clearly sharper than 1.7 and it gives a cooler tone.

True.

Yet 55/1.7 is still my personal favorite.
Has some feel/vibe to it, I'm struggling to replicate with other glass.
I believe this is thanks to just the right combination of spherical aberration, generally smooth transitions and some vague structure in the bokeh.






The only 50mm I've had, capable of competing with these 55s on bokeh quality, is Canon FDn 50/1.2 at F2.
None of the 50/1.4s I've had are close, be it stopped down or wide open.

Another honorable mention is Minolta 58/1.4.
Once you get past the first two uninspiring aperture stops, bokeh quality suddenly jumps straight to the top-tier at F2.8.

Probably better to shoot static on 1.7 but not running children )

The 55/1.9 was an oddball lens that was only sold in the North American (I believe) market with the SRT100, never in the catalogs on its own. It reputably does not have the full Minolta coating treatment.
The 55/1.7 was standard for several Minolta bodies from 1966 until 1973, and surely has different coatings and possibly optical "tweaks" (ala Rokkor 58/1.4) throughout its tenure. So one must be careful with blanket observations regarding the 55/1.7.
Plus of course the 50ish year-old age of any sample we acquire...

Silver aperture ring, Celtic-style rubber focus grip, distance scale in feet only. As you say, an oddball finish for a Minolta lens.

I have the Rokkor PF 55mm f/2, it's one of my favorite standard lenses. Best thing is, I got it for free.
