Lens for MX

I purchased an MX body and would like some advice on a good lens to use with it. I like to use my FA31 Ltd. but I'm wondering if it will be too wide? Everyone talks about using this lens with a "fast fifty," which I believe that was part of the kit when the MX was sold new.

M 40mm f2.8 - compact just like an M body and a nice focal length on film. Can be had for ~$75 if you can find one.

OTOH the fifty is probably a better optic.

If a FA31 is already too wide then I guess a fisheye is out of the question . . .




But if you want a fast fifty then maybe this is more your speed . . .

LOL!! I'm not saying the FA31 is too wide....I'm asking for some advice since I've only shot the FA31 on my K-5 on which it's more like a "normal" 50mm. Seriously though...what do you think?

P.S.: Nice looking fisheye!

I personally love the 50mm on my ME, it's a great general lens for walking around (which is what I use my ME for)

It really depends on what you want to do with the camera.



As I said above, a 50mm is a good base to start with, and they're dirt cheap (I paid $40 for my ME with a 50mmF2 attached)

MX Lenses?

Hello CMG,
The classic "formula" for manual and/or film cameras was a doubling/halving of the focal length with each lens. For example, suppose you started with an "M" 50mm f/1.7, which is a very good choice, by the way.
Next you could add a 28mm (manual focus lens, K, M, A, etc).
Then a 100mm (up to 135mm, really. It's a general rule of thumb).
Last, a 200mm.
On a film body, those lenses would see you through 90% of the shots you'll encounter. You could later go wider or longer, or add a zoom.
Most of these lenses can be found for less than $100 USD.
Just a suggestion,
Good Luck!
Ron

Thanks very much for that really helpful info! I wasn't aware of his formula...but it does make sense! If I purchased an M 50mm f/1.7 how would I use it on my K-5? I shoot manual most of the time as is, but I know that his lens will not communicate with the camera.

What does too wide mean? 31mm might be too wide for portraits, but not for landscapes or interior photos.

I'm sure the 31 would work great in most of the situations where you'd use a 28 - though as others have said, you could assemble a great manual lens kit for not too much money. You might find the 31 a bit of a pain to manual focus due to its short throw and lack of damping compared with older lenses, but you might be fine with it.

As for using the M 50 with a K-5, here's a helpful thread - https://www.pentaxforums.com/forums/pentax-beginners-corner-q/110658-using-ma...x-dslrs-f.html

...street, landscapes....not as a traditional portrait lens, but still good for capturing people on the street, etc.

....well, there's the FA 43 ... but the 50/1.7 or 1.4 are both excellent and worth while.

In my opinion, not many have the ability to use the FA31 on full frame, after all. Some say it's even more magic than on APS-C.

I'll add my vote for a 50 f1.7 Pentax-M. I have quite a collection of 50s, including the f1.7, f1.4 and f1.2. In spite of the cost, I think the f1.7 outperforms the faster lenses (except at stops wider than 1.7!).
