The article is super! Apparently, a good lens! It’s a pity that it’s not for Nikon. The photos are interesting. Now I also began to clap mainly only with ISO 100. Question about the exif'a of the first photo with tulips, such a long exposure of 1/80 with such a high ISO of 640, was it really that dark there?
Yes, the sun has already set. Photographed on the balcony, on MDF, with MDF, the real aperture value falls somewhere to 3,2-3,5. So we got such an excerpt. For Nikon, there are many great alternatives, which are the native manual fifty fifty 50, or our proven Helios-1.4N.
Yes, I myself have often thought about the Nikon 50 1.4, but some boring bokeh compared to 81n. I will probably never change Gelik! The only thing - sometimes you want autofocus in it. But if you don't find fault - the best lens for all occasions! Especially on fx probably!
I also think so, I have two G-81N.
And how do you like Nikkor-HC 50/2 in comparison with Helios and the new Nikonov poltikov.
Nikkor-HC 50/2 did not stay, I can not say.
These takumars are many different (threaded): depending on the year of manufacture and the presence of enlightenment. There is just super takumar 50 / 1.4 and super multi coated takumar 50 / 1.4 and smc takumar 50 / 1.4
For example, I have such a couple:
http://s018.radikal.ru/i515/1206/43/1fb74ff8cf95.jpg
smc takumar (the one with traces of a fall) - the last threaded version, as I understand it, is an analogue of the one you describe in the article.
PS. You seem to take lenses to describe on the site? Of relative rarity, I have a takumar 85mm / 1.9 - I can let you play
I will be glad to accept for a review. I am in Kiev, if you have the same location, then you can cross. My contacts are easy to find on the site. Anyway, thanks for the suggestions.
Pentax A 50mm 1.4
What is his mount, and is it possible to attach it to Nikon?
Bayonet K, like many other Pentax. Converting to Nikon is difficult.
Easily! Nikon adapter and you're done
ps M-42 - Nikon
Arkady, good day * morning, evening, night - also good :) *
Could you tell me, is the aperture ring of this lens with fixed intermediate positions between the stops? Or does it spin freely without them? In short, is it suitable for video?
Thank you for the site - a very useful business!
No, rattle in the footsteps.
OK, thanks. Well, I'll go look for a high-aperture "video fifty" further)
Hello.
Can you tell me on the K-7, too, only the manual shutter speed and aperture mode?
There the bayonet mount is slightly different from the K-10.
Arkady! Tell me pliz ... maybe you tried this SMC Pentax M 50 mm 1.2 Can you tell us a little? Thanks.
I have not tried this.
can you explain ... just bought this lens for pentax kx. but the shutter button does not work, this lens has a wider aperture blade than a standard, what options can there be?
There is a Pentax 50 1.2 how to combine with Nikon d5100. Thanks for all the reviews it is NEEDED !!!
Good night !! Tell me please, I have a fotik EOS Kenon 1100 D WILL I GO TO HIM Super-Multi-Coated TAKUMAR 1.4 / 50mm lens? And is there any sense in buying such a fotik or is it easier to fotik a new one !! ???.
You have a slight inaccuracy - the first 8-lens Takumar 50 / 1.4 was just NON-radioactive, subsequent versions, up to the last M42, before the bayonet ones, are all radioactive, to a greater or lesser extent. It was checked personally with a dosimeter.
Inaccuracy removed. Thanks.
Arkady, hello
I bought myself the same lens, only A. The diaphragm’s tongue walks very tight, the camera doesn’t support its lifting, maybe you know what can be done?
Thanks in advance
Best regards, Dmitry
Petals in oil, need to be cleaned.
Please tell me what is the difference between Pentax-A SMC 50mm f1.7 and SMC Pentax-M 50mm f1.7?
can you put it on kenon?
Yes, you can.
Good day, Arkady! I read on the forums that it is possible to use the SMS Pentax-M 10: 10 1 mm lens on the Samsung GX-1.7 (Pentax K50D). I put the lens - F- lights up, in manual mode no change and the shutter does not work. For the first time on a digital camera I work with a manual lens and I'm afraid to do something wrong. Can you tell me what is the reason?
It seems to have figured out the shutter, changed it in the settings menu. I have not mastered it to the end, but the first photos are pleasing. An interesting lens!
Wheel in mode M and a small button with a green dot, and a lot of good photos.
how did you manage? I bought today, my F- and M are also lit
Good day, Rinat. Please tell me if the focus indication lamp lights up when using SMC Pentax-M 1: 1.7 50 mm on the Pentax K10D
To begin with, we program the “green button” for exposure metering: Menu-my settings-p.14 (for K200): * green button in manual ... * -pp2 (diaphragm pior) -OK! When shooting, the wheel is on “M” , switch Af-Mf in Mf (otherwise the shutter button may not work), set the aperture. Then everything is simple: I focused, pressed the green button, caught the shutter button. The masterpiece is ready! +++ THANKS, Arkady, for the most interesting reviews !!! +++
Bought a SMC M50 f1.4 with red enlightenment, what's the difference?
My favorite lens, I’m practically not taking it off the carcass. On Pentax K-20, problems with aperture recognition were not noticed
Good day! Help me please! I bought a Pentax K-30 carcass. And I wondered which poltos to buy: Helios 81 n or this SMC Pentax-M 1: 1,4.
Help me please!
Thank you!
This is my favorite lens I use on kenon.
For connoisseurs of this lens, there is a copy of the first version, the price is negotiable, anyone interested write Foravar108@yandex.ru
Good day. There is this lens with traces of fungus on the lenses. Is it fatal to him or can it be fixed? Is the lens disassembled? Does it have bonded lenses?
