It sound to me like the same lens - the 'a' presumably refers to it having the a setting on the aperture ring. As I understand it the original 'K' lenses did not have this, then the 'M' series came along with it.

The 'A' setting for aperture came along with the 'A' series Nigel. Functionally the K and M series lenses are identical but the more recent 'M' series were deliberately built to a lighter and more compact design, in the view of some with a detriment to quality (in general, there are always exceptions).

Anyone know of any other old manual lens or any other K mounts that would suit my street stuff?

Im finally understanding the rendering issues that old lenses have - some of them struggle with front lighting and CA etc but I think they are fab to use

The DA 35 2.4 is a great lens and might opt for it if theres one going cheap on here

Hi Alistair

I can't directly comment on the M28mm F2.8 as I've never owned one, but as Nigel (McGregni) pointed out I rave about the M28mm F3.5. Maybe this lens is not quite fast enough for street photography, but it is a sharp little beast and has quite a reputation for being one of the best 'affordable' legacy lenses out there. I would ditch the F2.8 if I were you and either go for a F3.5 (they're not that difficult to find) or buy something different altogether that's more modern and has AF, although that will cost you more. I've been looking at your shots with the M28 F2.8 and my thoughts are that they would be blown away completely if you took the exact same shot with the F3.5 version. I'm making the assumption that your shots were correctly focussed when saying this.

Most of my lenses are old Pentax manual focus ones. I think they're all pretty decent but they're not all cheap. Best bargains were the 28 and 135. I really like the 50/1.4 which would probably be the one I kept if I was only allowed one prime lens. My manual primes ......

SMC20/4M
SMC28/3.5M
SMC35/2M
SMC50/4M macro
SMC50/1.4A
SMC135/3.5M
SMC200/4M

For all around fun and great image quality I'd throw the SMC35-105/3.5A into the mix - super zoom lens built to last with more than decent IQ. Build quality comes at a cost though...it's quite heavy. There's been one for sale in West End Cameras (Tottenham Court Road) for a while now. It looks mint to me and they've had it long enough that I suspect haggling may be worth trying!

The M40/2.8 might be worth considering. Not particularly well regarded generally but I was pleasantly surprised. Some thoughts here. For a wider option then a Sigma superwide 24/2.8 is a fine little lens.

I agree with Jon about the 50 F1.4, I have the 'M' version and it is brilliant, I would not part with it, especially after using it on my K-01, which is where it lives permanently now. However, it might not be wide enough for you to use as a walkabout and street lens.

You really need an 28/2.8A ... at the right price.

I have an A28/2.8 and an M28/3.5

Years since I used them to be honest, but from memory I remember them being fine.

my vote for f-series
http://kmp.bdimitrov.de/lenses/primes/wide-angle/index.html
The Pentax SMC-F 28mm F2.8.
This was announced with the first of the Pentax AF cameras back in 1987, and only produced until 1989, when it was replaced by the FA series of lenses.

So, to start with, what do you get?
Well you get a typical 80's style of outer design - Dark grey, with bold red graphics. Not pretty, and a bit retro.
Build - The outer casing is plastic, but the core of the lens is clearly metal. The filter screw is metal and the lens is quite weighty. The whole effect though provides a very solid and well made lens.
Size - think of the FA35, FA50 and DA35 and you get the idea - small.
Handling - The focus ring is small, ala FA lenses, but solid and grooved, so it is ugly, but works very well. It also has a window for focal distances. more like modern lenses and Pentax's own DA* range.
Now the important bit

Performance.
Now I was lucky recently to compare this lens to the later FA 28mm lens, which has a completely different optical arrangement. The FA was good, but the F is better. It is so sharp! Not that the FA is not, but the Next sentance will explain why.

Use on Digital.
Here we go, A 25 year old lens on a modern K-5 body, surely the CA is appalling?
On the contrary, the Lens on digital, even the demanding K-5, the CA is practically zero! The FA (mentioned above) does show a small amount, but this lens? nil!

Sum up
The F-28mm is a fantastic lens, which gives you true FOV on APS-C. It is not quick, but if you want a small sharp lens, then try and get hold of one of these. They are rare, and demand a premium, but they are worth it. If you can't get the F, then the FA, is an excellent substitute.

CA never bothers me. it's easily removed.

Why don't you try the Karl Zeiss Jena-M 28mm f2.8. It definetly wont be any worth the the Pentax version.

It is not made in Jena, but in Japan (maybe by Pentax) but it seems affordable .
There is one on the internet: 251442498371

Also there are quite a lot other manufacturers which have this focal lenght
in a K mount.

I just now had a look on Ebay for Pentax 35mm f2.8 lens. there are hundreds of all makes and sizes .

If none of them suits you, you can always look for the Pentax FA31 f 1,8

The focal length is quite close and I don't think you can complain about the quality of this lens (except the price maybe)

I too have the m28mm mk2 and it is great same optics as the A28mm the give away for the mk2 is lack of silver decor ring on the focus ring.

The K28/3.5 is excellent.

If you want a K35/3.5 I'm thinking of selling one.
