So do I. Great value for the excellent color & rendering.

My CV 35/1.4 SC and ZM 50/1.5 have some smooth bokeh but focus shift may be a problem with both lenses on RF cameras. Beware of flare with the CV also. Among lenses i have no experience with, the current CV 35/1.2 and CV 50/1.5 have a very good reputation.

Get a Jupiter 3 (50/1.5) / Jupiter 8 (50/2) / Jupiter 9 (85/2), have the lens shimmed to work on your M body and enjoy the images :)

 

the J8 should cost you little more than the cost of postage ... The j3 is usually the "most expensive" of the bunch at appx. €200 ... The j9 is an excellent portrait lens

 

Best advice in this thread so far!

The key is to get them adjusted properly.

 

Other than that, I have seen no other 35mm with as dramatically beautiful background rendering, as the 35/1.2 v1 Voigtlander lens, but I would not consider it a budget lens, with prices still easily reaching 800 - 900 USD second hand (they are not made anymore, so second hand is the only way to get one).

For smooth and attractive bokeh my advice is the Sonnar lens design, which is available in a number of lenses. As mentioned earlier the Zeiss 50/1.5 ZM Sonnar or the Russian Jupiter Sonnars would be excellent choices as would the older Zeiss Opton 50/1.5 Sonnar, the Carl Zeiss Jena 50/1.5 Sonnar in LTM and can be used to meet whatever budget you have chosen.

 

One that is rarely mentioned but is an outstanding lens is the Rollei 40/2.8 Sonnar HFT in LTM. F/2.8 isn't as wide as some of the others but it is better corrected and offers the Sonnar bokeh signature at a similar price to the Zeiss 50/1.5 ZM Sonnar and with no focus shift. Note: if you're planning to use the Zeiss ZM wide open check that it's optimised for f/1.5 rather than f/2.8, which many of them are.

 

Pete.

I know the OP wants an M mount but the Summitar is a good bang for the buck lens too and good copies can be had for little. To my eyes at least it has a nice boke. The coated versions with ten-blade aperture are the best imo.

That last shot through the restaurant(?) door is pretty much a textbook example of "bad" bokeh. Those bright-edged cat's-eyes blurs on the right are exactly what is meant by bad bokeh. Leads to double images, as in the circle dead center and the woman's arm.

 

I'm not saying the lens is bad, or that you shouldn't like the effect. But "good bokeh" - if that is what you are looking for - means OOF blur circles that are always brightest in the center, and fade away softly at the edges.

 

The 50 f/1.5 c/v shot of the water pump is in the same vein - doubled-up images of the wall lettering top left, and clothing rack stanchion center left.

 

The flower shot (same lens, different camera-subject-background distance relationships) is closer to neutral-to-good bokeh. The blur circles are brightest at the center, and fade away at the edges, without hard outlines. Just a hint of bright edges and doubled images in the middle distance (yellow-green hedge).

Not a bargain, but 50mm 2.0 Summi ver IV is gorgeous. About $1400 used on Ebay (am salivating for a back up but just can't rationalize 2 examples of the same thing when the current one has been perfect for about 20 yrs).

 

The Zeiss focus issues in searches seem to fixable with a good tech, but you'll be limited to what 'sweet spot' you asked to have it calibrated for.

 

Can anyone back that bit of research up?

Those doubled up letters are exactly that. A neon sign with double tubing.

Consider a 90mm elmar

 

 

Agree. For real budget (around 180-200€ for a good used copy) the 90mm Elmar-C is an excellent performer. Can't post photos to the forum right now, but I think this is a reasonable example of the bokeh wide open (I think)

Andy,

 

With due respect, the OP asked for a lens "that has a large aperture and produces nice bokeh and is priced on the lower end of the scale". It is a subjective question, thus, which is why I suggested the Summitar, a lens that I find pleasing.

 

I note that the OP didn't ask for a lecture on what is "good" boke in a technical sense, though lenses producing such can probably be also be found at the lower end of the scale. I'm sure he'd be interested in hearing your views, as an experienced photographer, on that. Incidentally, MJ Hussman not long ago wrote a piece in LFI on boke and out of focus rendering so if the OP wants to dig deeper into circles of confusion that's a good place to start.

 

For a lens within the parameters (including focal length) set by the OP, I still maintain the Summitar is capable of pleasing out of focus rendering.

Harold, as nice as your shot with the Summilux-M 50 Asph is, in my view that is not a lens which is priced on the lower end of the scale. Btw, does the Canon 50/1.2 you shot with fit on an M?
