I have no UWA in my collection. I would like something like 20-21 mm . No fish-eye.
I found a SMC Takumar 20mm 4,5 for 180 €.
What would you recommend ?
I have read that range-finder UWAs are not suitable for the A7 ( sensor issue).
Thanks

You cannot generalize that. First of all you're lucky that you have the A7 and not the A7R, because the A7 seems to be more suitable for manual lenses.
As far as rangefinder lenses are concerned, the CV 4.5/15 causes colourshift in the corners whereas the 5.6/12 doesn't, so they say.
You can use the APS 10-18 for NEX in the crop mode of the A7 with pretty good results.

I have the 7R and have the following:
Voigtlander 15mm f4.5
Voigtlander 21mm f1.8
Nikon AF-D 20mm f2.8
The 15mm does have a colour shift (but really no worse than when used on a nex 7). It is pretty sharp across the frame but needs PP to be usable (as it did with the nex7). The 21mm f1.8 is very sharp but does vignette wide open. It's a little heavy and not cheap but an impressive lens. The nikon I have for my slr rig. I found ion general SLR lenses vignette less than the rangefinder equivalents and it's still true of the two 20/21mms but at f2.8 it's not a hug difference. The voigtlander is sharper than the nikon, even with both wide open (but my nikon is a bit battered).
Not really offering any recommendations, just experience! My only issue with the cv lens is the weight, I shoot longer FLs I general, so I half think a f2.8 would be a better aperture for me as it's less to carry. The 15 is stupidly light of course. |

Or Voigtländer Ultron 21/1.8 (expensive) also seems to work very nice (a few samples with A7/r at SteveHuffs website)
What's your price limit?
Does the lens have to be very good from corner to corner?
MF lenses only? Do you consider LAEA4 or similar adapter?

Not exactly 20mm  , it's quite large and there's a lot vignetting at wide apertures on FF but very sharp and stopped down good from corner to corner. It's also quite cheap!

You can use Samyang 14mm in crop mode and it will became 20/21mm lens

Avoid the takumar, its got heavy barrel distortion, almost like a semi fisheye.

do you know if this also is true for the Pentax M f4/20mm? A lens that has attracted me more than the Takumar, mostly for it's much smaller size.
Talking about wide angle SLR lens but compact of course also Olympus Om Zuikos f3.5/21mm and f2/21mm come to my mind, both said to be very good performers, I think.
I am surprised no one yet has mentioned the Vivitar / Tokina f3.5/17mm which used to be recommended in this forum a lot, just like the Flektogons and I like my MIR f2.5/20, there also is a Mir f3.5/20.
That's all SLR lenses which means much bigger than RF lenses of course, but the O.P. has been considering the Takumar which is big and all these lenses most likely won't have corner issues.

In full-frame (5d2) the corners will come a little more darker so in A7 should be the same.

The smc M20/4 on crop sensor? or on FF?
I havent try it on canon FF, but on a pentax, it delivers very good results. Can't see any barrel.
Zuiko 21/3.5 (mc and non-mc) also very good on canon FF. About the same size og pentax.
Nikon 20/3.5 ais is bigger.
Vivitar/Tokina f3.5/17mm is sharp and wide, but i don't like the rending/color as smc or zuiko mc.
Colors are a bit flat, less contrast. |

while I haven't tried the M lens on FF, its much better than the takumar with regards to distortion on crop.

no I haven't, with Vivitar/Tokina, Flektogons and Mirs I merely mentioned those which used to be recommended here often, though most users then might have been using APS-C.
see samples taken with the Mir 3.5/20 on 35mm film: http://www.flickr.com/search/?w=23865740@N00&q=mir%2020M
and taken with the Mir 2.5/20 on film: http://www.flickr.com/search/?w=7667916@N03&q=mir%2047

The f3.5 Mir is a nice lens: it is sharp, it shows good color rendition, more than decent distortion control, and it's not too big (quite smaller than a flektogon 20/4). IMHO for 100€ is a goot deal. On the other hand, it flares like mad because of its big convex front element, and one of the two copies I've had had some slightly annoying mechanical plays (the other one was much better) : nothing extremely serious, but better knowing it before.
If I had to buy a wide for FF in the 400-500€ price range now, it would be the zeiss distagon 25 2.8 for contax without hesitation, but I understand it may not be wide enough.

yes it is not wide enough as the first test I did with my SMC 28mm 3,5 is satifying ( I bought this lens in 1970 ! )
I found an offer for a Mir 3,5 MC including a hood. It looks there are two versions , single or multi coated.
The Mir seems cheap . I should perhaps try it and sell it if I don't like it. I won't loose much money.
The Olympus looks much more compact. I shall try to find some users feed back.. |

Yes, I have had two copies of the MC version, so all the things I said above were referred to the MC Mir 20 M.

Im not sure if you can find one for 500 euro but the smc pentax k 18mm f3.5 lens
is excellent in all respects if a little large in length of the barrel. sharp, high contrast,
excellent color saturation, low distortion. built in filters. excellent build.
