Better lens to replace Konica 40mm, 50mm, & 57mm?

    So I've had the Konica Hexanon 40mm f1.8, 50 f1.7 and a 57mm f1.4 for almost half a year now, with the 50mm being the newest at 3 months.

    For the most part, I like the sharpness, speed, contrast (when stopped down) and quality of the photos that I can take w/ each lens, but I feel that the bokeh is rather lacking for each lens. They just don't have that rich, creamy bokeh that I've seen in Nikon/Canon lens. Granted, I didn't pay nowhere close to some of their lenses, of course.

    Are there any good particular lenses that you think would could match the sharpness, stopped-down contrast, aperture and quality of these lens, but could also deliver creamier bokeh?

    I'm looking for specifically a 40-45mm fast lens.

    Thanks guys!!

    I'd have thought maybe an OM 50mm? could do the trick or a Canon FD 50mm, both some in f1.8 and f1.4 variants, I'd guess you'd want the f1.4

    Do they have something fast in 40-45mm?

    The Pentax 50mm f/1.7 gets good reviews and is relatively inexpensive (around $60-80 on eBay). I have one but haven't done enough with it to have a strong opinion about the bokeh.

    Having a look through the lens sample gallery the Canon FD seems to go from 35mm to 50mm so no 40/45

    Only other 40/45 aside from the Hexanon I know of is the Minolta MD Rokkor 45, or a Pentax DA Ltd 40mm which is a current lens but at f2.8 its not as fast as the Hexanon 40mm you already have.

    Hey Joe, I just did a quick test with five lenses.
    Although out of your focal range my Helios44 (58mm, F2) has a smoothest out-of-focus areas, and is sharp at 2.8 while 'glowing' at F2.

    Rich, creamy bokeh? 50mm Summicron. Any 50mm Summicron. This is a recent version on 35mm (probably Tri-x) but the collapsible version I paid GBP150 for was just as nice and actually better for b/w work due to slightly lower contrast. Very nice for people.


    For less money, here's a Zuiko mij 50/1.8. Definitely Japanese but still nice. This is on 4/3 (Olympus e-520, eBay adapter).

    j0e - I have the Hexanon 40/1.8 and a Canon FD 50/1.8 and you're right about the Hexanon. The FD is definitely smoother than the Konica. That said, I plan to sell both of them (and their adapters) and buy the new $400 Olympus 45/1.8 when it ships. Oly makes great lenses, and, after 6 months of fun, nostalgia and out-of-focus shots with legacy manual lenses, I'm ready to go back to full auto :)

    40mm IMO is overrated and a POS, never tried the 50mm but can't believe you don't really like the 57mm - which I love. Bokeh is fine so long as you're close enough. The issue IMO is the 2x crop factor. That 57mm will give you creamy bokeh at a wider image on a full frame camera, wherease it will give creamy bokeh for portraits/head shots on m4/3. If you want full/upper body shots w/ bokeh, get a 100-135mm lens, if that makes any sense. But so far I'm pleased with 57mm 1.4s bokeh - the 1.2 version is supposed to be better bokeh wise so maybe get that and ebay the three hexanons to help pay for 1/3 of the 1.2

    I actually have a pre-order for that Olympus lens. I am hoping that it will be good enough to replace all three lenses. Yea, the missed focus due to manual focus does get pretty sore after a while

    I never really saw the attraction of the 45mm but after a couple of days playing with a Canon 50mm FD I think I might be making a pre-order if the price remains good when its released in the UK.

    I tried a bunch of legacy 50s. I think the Takumar was my favorite, but too soft wide open. The FD was best in color and contrast, but it was heavy and the mounts I find fiddly. I sold all my legacy glass (except my OM 50 macro) a few months back, and decided to just wait for native lenses. I think the wait will be richly rewarded!

    I'll put in a vote for the Pen F lenses: 38mm f1.8, or the 40mm f1.4. I have the former. Very compact! I prefer the Pen to the Hexanon 40.

    I only know Pentax lenses and can personally recommend these 2; these shot with lenses wide open...

    Pentax-M 50 f1.7 (k mount) this lens is a cult classic among Pentax users. Can be had pretty cheap < $60 and meters well on m4/3

    Super Takumar 50 f1.4 (m42 mount) another cult classic and I think this one maybe a bit sharper wide open v the M 50, but we're only talking a few hairs. <$80

    I have not run into a good Pentax 40mm lens, but can also highly recommend the DA 35mm 2.4 L @ $180 it's new and an AF. There should be a ton of lenses in the 50mm range that can produce exquisite bokeh...

    You could also get one of the older Pentax M 40 2.8. It would be cheaper and neither lens would AF anyway.

    Update: I checked KEH and the M 40 is $133 and the M 501.7 is 43. Given the $$ difference, the 50 is a no brainer. I currently have the A 50 1.7 which is quite nice.

    The Pentax 40/2.8 pancake is a cult lens that doesn't deserve its reputation. The 50/1.7 or 50/2 are better and much cheaper. The 50/2 isn't even that much bigger! I've had all three back when I used K mount gear. The only advantage to the 40 was that you could get an ME or MX body into a coat pocket with that lens mounted.

    You should take a look at a Voigtlander 50mm f/1.1

    Not in your range, but the rokkor 58 1.2 has creamy bokeh I think you'd like. Google rokkorfiles they have a few comparisons one being bokeh, of the rokkors. Good luck with your search.
