smc 28mm /2.8 -k -m -a compare..

hi, can anybody compare the lenses? maybe some of You owned two or even three versions... I want to buy smc 28mm and I'd like to know if there are significant differences in IQ mostly resolution/aberration/contrast/colours between the models -k -m and -a. yes, I've read the review section, but it's not the same that comparsion..

thank You

I have the Takumar A version, so a lense without SMC, and it's a good lense, but because it doesn't have SMC it produce some CA often ...

The A is better optics than the M, there is an M version II which has the same optics as the A but not A setting for aperture, it is a nice lens I have the VII.

Not sure about the K, likely as good as the A

I have the M 3.5, it has excellent iq though a little slower than the 2.8, it is considered the sharper of the 2 lenses though

some samples in my Single in January album
Paddy shot the 28 2.8 in January for comparisons sake (search single in january you'll get both albums coming up

There is no K28/2.8 but a K28/3.5. The K28/3.5 would be my choice over the A/M28/2.8 or the M28/3.5. Check the lens review section.

K 3.5 is the sharpest.

A 2.8 is better than the M 2.8 (often, unless you have the rare M 2.8 v. II).

In general, I would suggest the A 2.8 because the auto aperture is a great feature, and the 28mm 2.8 is pretty sharp already.

I have other lenses for DOF like the several 50's. The small amount for DOF gain from 3.5 to 2.8 would be negligible in any case

Now if it was the f2.0 28 k that's a different story

Thanks for the compliment on the shots. At this point I'd rather city/night and summer came together for a while

I've used: K28mm f3.5, M28mm f2.8 and f3.5, A28mm f2.8.

K is the best, followed by M 3.5, followed by A, followed by M f2.8. I'd say IQ wise the A 2.8 and M 2.8 are close but obviously the A gives you the convenience of auto aperture. The A needs to be used with a hood, it flares somewhat bad and sometimes reproduces crappy colors, but if you enjoy taking "atmospheric" photos, A is really good for that!!!

I agree that the K 3.5 is best.

Another option is the SMC Takumar 28/3.5. It's the same formula as the K lens but is much easier to find and cheaper. It is also quite easy to find the excellent OEM metal hood for that lens.

I had an SMC Tak 28/3.5 and found I liked the bokeh of my M 28/3.5 better. Sharpness seemed similar. The sigma mini-wide II (28mm, f/2.8, A ocntacts, 1:4.5 macro) is also a nice choice.

I hope you are happy.

Remember, the 28mm is hard to properly focus, so make sure your images are actually focused properly before you worry that the lens is soft... if it's a good copy it's damn sharp.

Also, it really needs a hood.
