Takumar 300 6.3 that isn't a Tele-Takumar

A small number of these otherwise common lenses were marked a just "Takumar", before Pentax decided to name it Tele-Takumar.

The Pentax shaped elephant in the room is that Pentax made it pretty clear they weren't working on any new lenses- there's not going to be any pentax equivalents of the Nikon 135 1.8 or a 400 2.8 or any of that. After the 50 1.4 and 85 1.4 came out all they've done is drop lenses. Meanwhile Canin Nikon Sony are racing away with all sorts of state of the art glass.

if you like close portraiture then the eye tracking capability in the Nikon and such makes it easier to get striking portraits, in particular close-ups. its something that would have to be tried to see if the differences are something you would value enough to change setups.

as these are pretty cheap, go look on ebay for one that just says "pentax", and not "asahi pentax". pentax changed company name to just pentax in the 80s.
very new ones were outsourced outside of Japan.

M-mount lenses

Some of the focal lengths are smaller and lighter than their 1975 K mount equivalents. I think the "M" referred to "miniaturized", as Pentax was in "Lightness War" with Olympus about who could make the smallest 35mm SLR system. Mount-wise they are all identical and function the same. No one has ever really posted tests on whether the M lenses take better, same, or worse pictures compared to the K series lenses.

maybe they decided to use some thread lock or something on this lens when they put the back on.

I have one with fungus inside rear element. Usually theses long lenses unscrew into two pieces, since Pentax needed a fast method of inserting the elements. So far a little tugging has not made any obvious movement.

Takumar 55mm 1.8 preset and Pentax S located

Located a Pentax model S with the Takumar 55mm F1.8. The camera is jammed but the lens has survived. It does appear that the lens elements are identical to the elements in the more common Auto Takumar 55mm F1.8 Zebra, so if you run across a preset one that works but has glass damage, an optics transplant may be possible.

put up a picture of the back of the lens, I will compare with mine.

Most importantly, if you want to try a repair, do not try metal lens drivers to remove the front, order a set of rubber lens rings, try an Amazon search for "Japan hobby vacuum lens remover",

Demanding as in how all the mirrorless camera makers show sample pictures of things like people in sporting events flying around, and that the camera stays locked onto their eyes while you shoot them.

That's another reason Pentax gave up on large aperture long focal length lenses, like 300 2.8 and 400 2.8. They can't deliver enough shots on a DSLR to justify the cost, because the camera can't focus accurately enough to exploit them.

A subtle giveaway on what the Pentax system can and cannot do is to compare the Pentax web site pages for lenses like the 85 1.4 and 50 1.4 against the Nikon Z web pages for similar lenses. There are no notable sample pictures or videos of the lenses producing anything very demanding - mostly just landscapes and people far away from the camera.

Other posts similar to this yield the inevitable result that you will need either a new mirrorless system like Nikon Z or such to push focus accuracy to the level you want.

My advice on how I use the Z9 should be qualified with the fact that I'm not actually a very good photographer, and using the Z9 like this makes me end up with more keepable pictures. It's more like I play Photography Roulette, and the Z9 let me tip the Roulette wheel a little further in my favor.

I was just out doing flowers, and bracketed all of them. I found it really can be a hairs difference on close-up flowers and leaves. A tiny exposure difference can suddenly drop the gradation details in a flower petal or leaf.

Shooting this way, with bracketing is just one way to get a good picture. If you do lots of LightRoom then using RAW could do the same thing. The bracketing is just a mid-ground between no post-shoot computer work and lots of post-shoot computer work.

It might it the wind becomes uncooperative and the leaves start blowing.

Also, I found it was most useful to turn on 20fps and then also turn on 7 shot bracketing at 1/3 stop. I use that on difficult shots all the time, like flowers with black backgrounds, or even daylight backgrounds. You do end up with a lot of pictures to go through, but you will find the exact best exposure in the camera instead of any messing in LightRoom or whatever.

The Z9 and a big lens can be a workout, but with a neck strap I walk around for hours with it and don't really feel tired. For better or worse even their big zooms have lots of plastic in them, which really helps get the weight down. I have all the mega-primes, except for the Noct, and and S-line zooms, a backpack of that does weigh a lot.

When you get the 135 1.8 Plena and the 85 1.2 and use them for animals or portraits you instantly know how advanced they are than any DSLR.

The Z8 is a great camera, but don't overlook the value of having portrait controls for fast swaps to portrait orientation. The actual reason to use the Z9 is the gigantic battery. I recently shot 2000 pictures in an afternoon on the Z9 and still had half a battery. You can't do that good across a whole day, especially if you keep the camera warmed up and not in standby mode, but I've never exhausted a battery that was fully charged when I went out for a days shooting.

I'm sure I am not alone in wondering when the company that makes the MonsterAdapter for Pentax-to-Sony will make a Pentax-to-Nikon version, getting to use the limited lenses and the Star lenses on the Z9 would be a real killer app.

well I could have messed up and ended up with a Leica, which would make me look like a cool person, but never actually have good results when the lenses are tested. That would have been about 100% more again....

everyone should handle a Z9 or Z8 and see how amazing it is to shoot 20 frames / sec at 45 megapixels, with no sounds coming from the camera.

It isn't fair, but there is a definite payback for all the money. And Pentax had all that time to make improved models and did about nothing.

The trendy photographic style is subject isolation with every ounce of bokeh you can wring out of a focal length, and DSLRs will always lose in action shooting, because you almost always need eye-level shooting to track a subject while steadying the camera, and a DSLR can't do the kind of subject tracking a mirrorless camera will, since it can't use the sensor to do anything while the mirror is in the way. Which, of course, is why the K-1 has two modes of focusing, depending on whether you use eye-level vs the rear screen.

If they make a mirrorless K-1 it will solve most of their biggest disadvantages competing with Nikon, Canon, Sony.

Just to incite a riot... I have two K-1 Mark IIs and all of the full frame compatible lenses that were star-branded, and shot with them for about two years. Some things I shot, like static scenes or stopped-down exposures for large depth of field were fine and could be great.

But, after attempting to shoot photos using open lenses, or action shots, I found that the days of DSLRs are just plain over. I got a Nikon Z9 and their new lenses. The number of photos I keep after my outings went up by an order of magnitude.

If Pentax is going to just sit on the K-mount forever, and I highly doubt that the market would tolerate yet another new proprietary lens mount, then they should just make a mirrorless version of the K-1 Mk2. I think the remaining Pentax users would generate sufficient sales to pay for it.

in the US they are offered for sale at all sorts of prices, which if you check in ebay completed items, are rarely purchased. in Japan where more items go up on actual auctions they sell for 1500-3000.
