Well, SMC-K/M lenses are usually dirt cheap on the used market and some may come in handy regarding the current deep dark gaps in the Pentax lens lineup.

In fact the K 135mm f/2.5 doesn't even offer aperture priority on the K10D (due to the crippled KFA2 mount here) and you have to use stop-down metering using the camera's green button.

http://www.photozone.de/pentax/143-pentax-smc-k-135mm-f25-review--lab-test-report

I think that's what I've seen all over?

edit:

quote:

The M-series lenses, along with their SMC Pentax (commonly known as the K-series) predecessors, are the worst-implemented manual focus lenses on modern Pentax bodies. Pentax released its first digital SLR, the *ist D, based on their *ist film camera. Neither supported metering at all with the M and K lenses because there is no mechanical coupling between the lens and the camera. Gone completely are the days of shooting without electricity, I suppose.

Since then, Pentax has implemented a work-around, using the 'Green Button' while in manual exposure mode to 'automatically' stop the lens down and take a reading. If you want to shoot with M and K lenses in aperture priority mode, modern Pentax cameras will only shoot them wide open.

Oh wait, it should work fine if you're shooting wide open, forgot about that.

6x7 is really easy to learn because it's not square and it's got an optional prism you can put on the ground glass so you don't have to look down into it and can shoot it more like a 35mm.

This is why I love my ZX-M and ME Super, both can do aperture priority with and k-mount (or screwmount) lens, with A-series or AF lenses, the ZX-M will even tell you the aperture you have selected on the aperture ring in the viewfinder.

Its so retarded that they crippled their mount like this with their digital bodies, seeing as how lens compatibility is a huge selling point for Pentax.

I'm still having trouble seeing what the physical difference between a Pentax-A and Pentax-M lens are in terms of the mount. I'm literally looking at both right now and they look exactly the same, so I'm having trouble figuring out what part of the mount is "crippled" to the point where it can't read aperture.

It has no problem setting aperture on the A lens so why should reading the aperture on an M lens be any different.

I mean, I'm sure there's a really really simple explanation, I'm just not wrapping my head around it.

Stop-down metering in Av is OK enough for me for now, though it's approximate at best and I'm still trying to learn how to handle it on my M lenses.

See the little electrical contacts on the camera's mount? There's like seven at about the 7 o'clock position. They tell the camera the aperture setting on Ka lenses and up (SMC Pentax-A).

Now go find an ancient M42 lens. Note there's no aperture pin. A less ancient M42 will have an aperture pin. A late model M42 will have a tiny arm that indicates the aperture, it turns with the ring. The camera reads that. The K-mount uses the same system. "SMC Pentax" and "SMC Pentax-M" lenses have only that arm. "SMC Pentax-A" introduced the electrical contacts too. All (?) the lenses have both arm and electrical contact, but Pentax doesn't have the corresponding arm in the camera to read that because they want to sell you new lenses. Some of their film bodies are missing it too, recently.

It breaks up what is touted as 40 years of lenses and cameras that are all completely intercompatible.

I did an entirely unscientific ISO comparison on my K10d. All blurriness and missed focus is a direct result of my lovely tripod bouncing my camera around while I adjusted the ISO between shots. I can't overstate how lovely this tripod is. All shots are 1:1 out of camera :

ISO100

ISO 125

ISO 160

ISO 200

ISO 250

ISO 320

ISO 400

ISO 500

ISO 640

ISO 800

ISO 1000

ISO 1250

ISO 1600

I can honestly say I'm not too disappointed with 1600. This was a somewhat properly exposed scene though; if underexposed I'm certain 1600 will look like absolute poo poo as usual.

Just got it in, it's basically a holder for 4 extra AAs and an extra shutter release.

It gives the K200D a nice bit of weight, and the vertical grip part is perfect in my hand.

I just wish it had the arrow keys for AF-select, though I can reach the on-camera ones with some effort.

A great deal for $30, I'd say. Not sure if I would've paid the retail price of $129, though.

Both, but with medium format the same focal length lens would cover a larger field of view. So if you're used to seeing a photo like that with a 35mm format lens, at the shooting distance to get a similar framing you'd need to be further back (or conversely, a wider lens to shoot at the same physical distance of the MF one.) It's subtle and effective. It would be more obvious if you had several shots side-by-side shot in different combinations of formats, focal lengths and shooting distances.

All that doesn't matter if you can't make a good photo though. It's a great photo. Part of the unique look comes from the format.

Probably not. Read what I wrote above about the Pentax K lens compatibility. If they don't have the Ka contacts, you can mount them but they won't focus-confirm (I think?), you're stuck in stop down metering, aperture-priority won't work (except at full aperture), and you have to push a button to meter a shot and then hit the shutter.

If you have SMC Pentax-A (Ka) gear or up, you're fine. But since you have a K1000, I'm going to guess you have the vastly more common SMC Pentax-M gear which sucks on a K10d.


vvvv I love my K1000 SE. I would prefer a MX instead, but it's a bit much for an ancient camera. Now a Bessaflex... :swoon:

Need to find a better wide angle for it, though... I picked up a Focal (J.C. Penney brand, I think) 28mm f2.8 for $16 recently and it's utterly terrible. I suppose I should quit dicking around with cheap lenses and get some that are actually worthwhile. My Soligor 135mm f2.8 ($25) was a fairly functional bargain, and despite the fact that my starting lens (Pentax M 50mm f/2) is only worth five bucks, I love the picture quality that comes from it.

Paul MaudDib posted:

I think this is incorrect. I just got rid of my only Pentax-M lens to replace it with an A variant, but I'm 99% sure I got focus confirm messages in the VF with it before I sold it.

I think the question comes down do "do you like manual focusing" "do you not mind shooting in manual mode" "do you not mind hitting a button to re-meter between shots"?

If the answer to any of those is NO then you might want to look at getting an FA or DA lens (or just an A lens if you still don't mind manual focusing, but I assume you're OK with that coming from the K1000). If you don't mind it then you should be pretty OK with the K10d.

It's all about your expectations. You're not going to be point and shooting as quickly as someone with a Canon and a kit lens, or even as quickly as someone with a Pentax and a kit lens, but I think it's an awesome setup and the K10d is a great bargain camera.

Edit: I want the 50-A 1.7 but I might break down and buy a 50-A 2.0 -- I like the shots I've seen come out of those, and I shoot high enough ISO ( :love: K10d grain) that it should help compensate for the difference.

The 50mm/1.7 is rated more highly (IQ too) than the 50mm/1.7, and that's completely normal, as the lower f-numbers are usually just better lenses. What are you trying to say/imply here? :raise:

Oh, right. I was thinking you thought the 2.0 was a nicer lens and you'd give in and treat yourself to it!

The A stuff is sadly a lot harder to find than the M stuff. It's strange, I generally see either the M-2.0 or the M-1.4, and a few A-2.0s and a very very few A-1.4s. Very few M-1.7s or A-1.7s and almost no K series lenses.

For extra :psyduck:, from what I remember the M-1.4 has higher resolution than the M-1.2. It's the only exception I know to the lower f-number = better lens rule.

I'm a long time K1000 user and my favorite lens to use is the Vivitar 24mm F2.0, due to the kind of dreamy feel that you get at 2.0 and the sharpness at 2.8.

What level of functionality would I have to deal with? Reading about Pentax lenses, honestly, I'm just really confused. I can't figure out what exactly I'd have to do in order to just take a picture edit: with this specific lens.

I've got a K100D that I bought less than a year ago and a Sigma 18-50 f2.8 which is great. I decided to go with Pentax because I have my dad's old K2 with a few lenses and figured that going with a Pentax dSLR body and the old lenses would be a great way to start off (and to see if I'd get used to lugging around a dSLR).

Well it was a great decision, and before long I had to go get a proper all-around lens for my dSLR (that's where the Sigma comes in).

There's a lot to love about Pentax....especially if you have access to some of their older stuff.

The Pentax Firmware Hack Project is starting over at Pentax Forums. I'm hoping for the ability for the camera to remember the factor of difference between a full open aperture and the stopped down aperture on a manual K lens. That way you could just meter once for each time you change aperture.
