I,m looking for a very good 28mm in m42 mount. It must be at least f2.8 and sharp at f2.8 ( I prefer a bit brighter).
Bonus points are sharpness wide open, nice bokeh, 3d pop, price and size Smile
What are the options. What can you recommend ?

Sharp at 2.8 is hard to find, why would you shoot a wide angle wide open? Also, limiting yourself to f2.8 lenses excludes most of the better ones with 7 elements which were f3.5 like the Takumar 3.5/28, which is very sharp.

Mamiya-Sekor SX 2.8/28 might be the best one in M42, it has 8 elements.

Going to be hard to find a sharp wide open 28mm if you are looking for full frame.
On anything other than full frame there are lots of possibilities.
Vivitar 28mm 2.8 has a good rep.(Kiron/Komine?)
Kiron made a 28mm f2 which is excellent.
Hoya 28mm f2.8 gets great reviews and was maybe made by Tokina.
So there must be some Tokina 28mm 2.8's that are the same.
Takumar and SMC Pentax 28mm 2.8's are also very good.
Actually, any of these are fine.
No doubt there are lots more.

The Hoya 2.8/28 is a good lens, it is made by Tokina, the Tokina RMC 2.8/28 is the same lens. Sharpness wide open is marginal though, okay for close ups of flowers but not sharp enough for distance. You can say the same about just about all the other 28s too, wide open at distance, they suck because they were never designed to do that, the designs are optimised for f5.6 or f8.

Well, consider that on apsc a 28 is not exactly a wide, so being able to use it at f2.8 with acceptable performances can be very useful.

I second that, it's my favourite 28 in m42, I find it more than usable wide open - obviously it's better at f8.
Its main problem is corner performance, so it's a great lens for use on aps-c cameras, less so on full frame.
Another thing to consider about this lens is the difficult adaptation of mamiya sekor sx lenses: there's the "famous" protruding of the aperture ring that prevents the lens to fully screw in most adapters.
I also agree about the fact that allowing in f3.5 ones will give you a couple of interesting alternatives, such as the fujinon sw 3.5 28 and the already mentioned takumar.


That said, for overall performance/price, being f2.8 a requirement, the rmc tokina/hmc hoya is probably the best choice.

Indeed, It is for an APS-C sensor.
I would use for indoor photography in the evening and winter time. Mainly for 'Wider' family shots.
so it must be rather fast.
A fast 35mm is also an option.

The Mir 24 is a great lens, imho.

A 35mm lens on an APS-C is more like the old standard lens on 35mm film (50, 55, 57 etc)
A 28mm lens on APS-C is effectively a 40-45mm lens on 35mm film so not so wide as you might think.
You might like to consider a 24mm (= c35mm on film) for wider shots.
There are 24mm 2.8's around, and many of the makers already listed will serve well.

in M42 there is the Vivitar series 1 f1.9/28: http://forum.mflenses.com/vivitar-series-1-28mm-f1-9-m42-t8536,start,15.html
and I believe that there are Komine and Kiron versions of Vivitar f2/28 and a Vivitar f2.5/28mm.

S-M-C Takumar f3.5/28 is a very good lens

How about the Yashinon DX 28mm f/2.8? It seems to be a decent enough performer.

Yashinon DS-M 28/2.8 is better.

I use a Tokina 28mm on a D90 (APC sensor), resulting in a very practical 42mm focal distance.

It is not so great in a full frame camera at f2.8, but either are Fujinon nor Nikons.

+1 on the Tokina, my M42 RMC version is sharp wide open. The Pentax-M is also very good wide open, but i find it less "sharp" when used for infinity shots in landscapes or streetshots.

Then there is the Konica 3.5/28, but maybe not fast enough for indoors...

I have never had a Vivitar 28mm that gave pleasable results below f/5.6, they all could not match my Tokina, even the ones with a 28xxxx serial which people all find very good. They're overrated imho, they've become some kind of internet-hype. And i have tried at least 4 of them.

I mostly use AF for family shots indoors, i have a Sigma 28mm f/1.8. When it's darker inside, candlelight, i use f/1.4 MF lenses with high iso on the NEX, and that works just fine! Gives very nice images which capture the mood right, i hate flashlight..... Very Happy

I think the Vivitar 28mm F2(all version) are designed for close up so they do not perform very well for landscapes. Even the much older Retina-Curtagon 28mm F4 beats the Vivitar 28mm F2 in corner sharpness at same aperture. I like to use them for some close up and snaps. Generally, the slower one are easy to design and more sharp even at wide open. I would also recommend the Tokina 28mm(or even the 24mm) as they are cheap and readily available.

Those samples of the Tokina look great Very Happy

+1 for M42 RMC Tokina 28mm 2.8. This lens came as a bundle and I always thought RMC was Tokina's cheaper consumer series. Until i tried it. I am surprised that it took sharp pictures.

Both variants MC Cimko (Cima Kogaku mostly found as Beroflex) are very good.

+1 on the Tokina RMC, very good lens, better than any other third party 28mm I've tried, better than the common Ensinor/Clubman/many other brands, which is made by Cimko. I also think it's better than the Kiron 2/28, but maybe I had a poor copy of the Kiron. I had several Tokinas.

I agree about the Vivitar 2.8/28 close focus, I had two of them, neither was a good as the Tokina.

The Tokina is also commonly seen as the Hoya HMC 2.8/28.

Bollocks. Please read here: http://forum.mflenses.com/mystery-lens-ensinor-24-2-8-macro-t17823,start,30.html

You're talking about a different lens altogether.

This is the one you are guessing is made by Ozone:



This is the Ensinor/Clubman, made by Cimko, no guesswork needed:



Two different lenses, both very common, the Cimko is better than the Ozone. The 2.8/24 and 2.8/28 Cimkos are good lenses, unlike the other Cimkos which are mostly awful, especially the zooms.

Agree on Cimko is better then Ozone. Sadly none of the pictures you show above is Cimko. Not even the green diamond. Read here please:

I can second the recommendation of the vivitar series one 28mm F1.9.
The smc takumar 35mm F2.0 is also excellent.
