Here today with the Asahi Super Takumar 135mm f/3.5 m42 mount adapted to the Nikon Z5.
Try it out today see how it works! 135 millimeter focal length I think is
very nice on full frame, but of course that's going to be pretty telephoto.
Have to keep that in mind with your compositions. Minimum focus is 150 centimeters,
maximum magnification of 0.11x. Full frame field of view is 18 by 15 degrees.
This information is coming from the PentaxForums.com.
It's an extremely common 49 millimeter filter thread on there, so super convenient.
I do like the 135 millimeter focal length on full frame.
To get this going with the manual lens you have to go into the setup menu non-cpu lens data,
and then put the focal length and the maximum aperture for shake reduction to work.
See that it's on! I also have it set up to
do different buttons zoom in... AF On zooms in one amount. The video record button also
zooms in, and one of these front buttons. So depending on how zoomed I want to get
I can use whatever button to get focus obviously with peaking and everything else.
Nice thing about this camera you do get peaking when you're zoomed.
This lens is beautiful, all metal.. super smooth. See how close we can get here.
This is about the distance. I must have sensed it. According to the PentaxForums production years of
to 1965-1971. This is m42 mount, very adaptable to mirrorless cameras these days.
I'm using it on the Nikon z5 but you can easily use it on pretty much any mirrorless
camera... find the right adapter for it. M42 is a screw mount, takes a little bit
more effort to take off and put on the lens, but I do really like this mount.
It's simple.. functional.. works well! When you rotate the focus ring the front
barrel does extend from the lens. If you do use a polarizer on this lens you won't
have an issue with the front barrel rotating. It is fun trying out old lenses. In this case
probably pretty nice for portraits and such. On the community posts where I showed the three
new lenses or at least new to me they had said it looks like a lightsaber definitely does.
Maybe a little too thick I'm not sure how thick lightsabers are... but well this lens
is kind of from the original area most likely. It is challenging with the manual focus trying
to stay steady and zoom in at the same time. The aperture isn't anything to write home about
but I think it's within the realm of being usable. It is not the best for the bokeh..
background blur.. point source lights. It does have the six bladed aperture, definitely
not rounded through the range of apertures. Full metal construction on
the exterior of the lens. The focus ring and aperture ring have
machining on them for grip. I think that's the best way to do it. Works really well!
Asahi or Pentax made really beautiful lenses back in those days with the m42 mount.
I think they're always a great option for adapting with mirrorless cameras now.
The point is looking for something, of course we got the sun coming in here. It's always a good
option, but I feel a little cramped. Let's try shooting off into the distance here..
Oh, this is nice or it was nice for two seconds! I do have shake reduction on I'd rather use that
to give me the sharpest photos possible than trying to deal
with my slow shutter speeds type of situation. As long as you understand the challenges of old
manual glass I think it's a great option. It's fun to mess around with.
You have a huge multitude of mounts and things that you can use on these mirrorless cameras.
I am partial to the Pentax Super Takumar stuff because it is metal,
lasts longer obviously than junky plastic stuff. And it's just if you do the smaller apertures
you're going to get some really nice results out of them.
I believe that is horse... I'm in the danger zone of horse droppings.
This place used to be a tree farm and you see what happens to them when they,
uhh.. stay and not get used! Got nice uniform trees, looks super interesting.
My specific copy is not radioactive, which is nice. I did have a 50 mm f/1.4 for many
years that I did find out it was relatively radioactive so I eventually sold it. Once
I knew I didn't really want to keep it around. If you keep your expectations reasonable with a
lens like this, considering the age, considering coating technology and everything else...
You can get nice results out of it. Especially if you use smaller apertures.
It was difficult in a lot of these situations I wasn't writing down the aperture so it's hard
to say which photo was what, but I do think I got some nice pictures out of this photo walk.
You will get chromatic aberrations, color fringing, and things like that.
Obviously around f/5.6.. f/8 maybe, you'll get some of the highest quality images out of it
possible, but f/3.5 isn't too bad. For these photos I did adjust them slightly
from the RAW images just to get them a little bit more
interesting than straight from RAW with Acdsee Photo Studio Ultimate.
If I were doing jpegs they'd probably be more vibrant.
I think the point is don't expect the world from a lens like this but you can
definitely get some nice images out of it with a little effort and using reasonable apertures.
Overall I'm very glad to have this in my lens collection.
Build quality is nice, photos are nice, obviously it's not something super impressive
with the aperture but given the price and everything else it's fun to use I enjoy it!
Anyways I'm Scott of Photography Banzai. I hope you enjoyed the video, thanks!
