Not Thrifty Fifties

another 50mm lens question ... in the same vein as barbosas https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/24643-wich-50m...d-you-buy.html (weren't you called Pornflake?) and this other thread as well https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/20834-50mm-f-1...ght=50mm+zeiss

after using my M 50mm 1.4 for a while, i'm starting to like the focal length a lot. good for more artistic shots than the usual wide angle captures and a lot more fun to play with the narrow DOF. i wanna get a 50mm with an "A" feature to complete my travel kit of (DA21, a fast 50 and my Tamron 28-200 as backup) and use it as my main walkaround lens.

requirements:
-about 50mm lens
-fast!
-all metal construction: after using metal lenses a lot, i don't like plastic ones much
-manual focus lens, i think i'm more involved with the photo taking with manual focus
-smooth focus barrel: reference are the Takumar lenses
-"A" feature because stop down metering is fun, but can get annoying sometimes and i can't use the built-in flash

i realize that lenses like this will cost a fair penny, but i'm willing to spend on a good lens if i'm going to use it most of the time

so far i've thought of a few choices, kinda leaning towards the A1.2
-Pentax A 50mm 1.2: the narrow depth of field should be lots of fun ($569 Matsuiya)
-Voigtlander 58mm Nokton SLII: recommended by Kelly thePiRaTE!! (nice mountain photos!) but might be a bit too long ($379 Cameraquest the bargain of the lot)
-Zeiss ZK 50mm Planar 1.4: haven't heard much about it to be honest except on Photozone and people harping about Zeiss quality (<$500 eBay) ... did you know Logitech has a Zeiss Webcam? how they've sold out a great name

anyone have any comments or suggestions would be very welcome!

The Zeiss would be likely to be the same as the Voigtlander, optically speaking. I had a Contax Planar 50/1.4, and I liked it a lot. Compared to my Pentax M 50/1.4, it's definitely better at wide-open IQ and contrast. The color tone is neutral, cooler compared to the Pentax.

The new Zeiss has a little quirk however. It has the focus shift problem. But if you focus, meter, and shoot at the same aperture, you would be fine. The problem occurs only from F/1.4 to F/2.8. Also expect the construction of the lens to be top notch, but I suspect all of those 3 lenses would be.

With that said, I still prefer the A50/1.2. Don't have one yet, but will have one within this week. It's always fun to play with a 1.2 lens. Optically speaking, some users said this is the best 50 that Pentax offers. Some would say it's not worth it compared to other 50/1.4 (just go to Stan's Pentax site).

To complete the list, you might as well wait for the DA* 55.

Look... DoF is nice, but it's worth considering that the thrill of f1.2 is going to wear off fairly quickly, as it isn't really a huge DOF difference between f1.2 and f1.4. My suggestion? Go for the tried and true FA50/1.4 and save the $$$ for your next LBA adventure. There is always another LBA adventure

Why not go for the A50 1.4? All metal, manual focus, and you can find them for $150 or so, the cheapest of the lot.

As has been said, you may want to look into the SMC-A 50mm f1.4. It would meet all your requirements (except that it would be a thrifty choice).

I had a Zeiss 50mm f1.4 with my Contax system years ago, and it never failed to produce excellent results, but I have no experience with the new version.

As for narrow DOF, the difference between f1.2 and f1.4 is pretty small, but it may be significant depending on how you work. For example, focusing a 50mm lens at 6 feet, an f1.2 lens gives you 2.4" of DOF, an f1.4 lens gives you 2.9" of DOF.

Please substantiate this claim. I find stop-down metering a huge P.I.T.A., so if there's a way to make it fun, please elaborate.

Does it involve magic mushrooms?

Yes, i asked Adam to swap my username

I just bought the FA50 for the convenience of AF, maybe in the future i go for an F1.2.

The Voigtlander being 58mm which equals 85mm on 35mm, will it give a better FOV for portraiture?

Is there a major difference in FOV of a 50vs55vs58 ??

I have an 'A' 50 1.7 and I'm pretty sure the only plastic parts are the focus ring and aperture ring. The barrel feels metallic, but I'm not willing to gouge it to find out!

well it's fun because i get involved more and i get to use the aperture ring as well ... but holding the DOF "trigger" and then constantly pressing the AE-L button (K100D) isn't that great.. it's also fun cuz it's usually underexposed so i have to manipulate the exposure too.

what's wrong with Pornflake? ... 50 vs 55 vs 58 isn't that big of a jump from each one, but 50 to 58 is a rather large jump ... 58 is 87 equivalent so good portrait length. too bad i don't take portraits

now i'll have to consider the A series ... but something's still calling me to grab a chunky metal lens, and it seems at least from Photozone that the other lenses have higher resolution

Definitely the feeling of having a complete control over the whole process is nice. However, i'm curious as to why you need to hold the DOF "trigger" when you do stop down metering (e.g. using a M lens). With an A lens, you have auto diaphragm, so no stop down metering is needed. For a total manual lens (M42, K, M model), I focus at wide open, then manually stop the lens down to meter (exposure is never spot on with these lenses). It's definitely a pain if you need to shoot quickly. Otherwise, I do enjoy stop down metering from time to time. The click of the aperture ring is more enticing than the click of the rear wheel. Well, at least it's for me .

That was me who started the second thread. About the A50 1.2: it's only been about 60 days, and I might still end up liking it (or I might chuck everything and start over ... in that kind of mood), but I wouldn't buy it as a 3rd or 4th lens, but maybe the 6th or 7th lens. For one thing f/1.2 is incredibly hard to use. I shot about 50 frames this weekend with the lens, and end up with one that I liked with half-way decent focus, and it was at f/1.4; I missed the focus on all the rest, sometime by a wide margin. The M50 1.4, a favorite, is much easier to focus.

The A50 1.2 has a different "look" than the other 50s that I have, a little cooler and less contrasty at wider apertues; it's pretty unique so it's not unreasonable to own it along with other lenses of roughly that focal length.

Here's the pic I mentioned earlier, K10D, A50 1.2, ISO 640, 1/60s, f/1.4:

for my M50 and K100D, i compose by choosing the aperture on lens clickety click, hold the DOF trigger (instead of pressing the shutter half way, avoiding accidental releases, easier to meter multiple areas and easier to hold the camera) and press AE-L till i get an exposure that i like, release, focus and then shutter. am i using the term stopping down correctly?

i hope you like your A50 twinda1. just wondering though the brighter f/1.2 should make it easier to focus and compose for smaller apertures as well. other than the f/1.2 do you think it's better than the M50 1.4 (i have that too!)
