I am still finding a M42 perfect match for my SD15. This Super-Takumar 300/4 is not bad, but not outstanding. Anyone have any advice about which particular M42 MF lens match SD15 the best??

It's Super Takumar 300/4, not Tair-3 300/4.5

I think he was answering your question. But let me ask a new one. What is particularly wrong with these results?

OIC ! My apology to VolverineX !

My only issue with the lens is that it is not sharp on SD15.

I think I have a Tair-3. I have to dig it out and try it later then.

I don't think the camera body matters. Sharp is sharp, or not, no matter the body.
Now, its possible that a more dense sensor (pixels/mm^2) lets you pixel-peep more, so its easier to find defects in a lens and find the limit of its sharpness.

The answer is shoot at f5.6 instead of wide open.

Are the hand held shots or did you use a tripod?

It may be your focusing screen. Is it sharp stopped down? I have lenses that, on my K-7, AF perfectly and MF somewhat soft because the focusing screen isn't shimmed perfectly. (With an AF lens, I can verify that the focus is off because of the focusing screen.) However, if you stop down to f8, f11, or f16, then most any tiny issue with the focusing screen will be a non-issue, so that will tell you if the issue is your lens or your focusing screen.

I see. Perhaps my copy of Super Takumar 300/4 has defect since my Takumar 200/3.5 performs much better (i.e. sharper) on SD15. : (

Yes, I know. But that will reduce some speed .

You are probably right that it's due to poor focusing. However, perhaps it's more due to my poor eyes than the screen. : (

The Tair-3 is only so-so in sharpness wide open, but close it to 5.6 and it is very sharp. I wouldn't be surprised if your Takumar is the same. With a 300mm lens you're still going to have a shallow dof at 5.6. Honestly, I don't think you'll find a 300mm lens that is razor sharp wide open, they just weren't designed to be so.

No. It's my bad habit that I never use a tripod.

I have a habit of not using any tripod. So, 5.6 handheld is increasing the challenge . Crying or Very sad Crying or Very sad

300mm handheld is always a challenge, if you use long lenses often, perhaps you should think about a camera with in-body stabilisation, I think the Pentax DSLRs are supposed to be good in that regard. Or maybe you can try a monopod?

Before you look for another lens, I suggest testing this one on a tripod and focusing carefully (using a LiveView feature if your camera has it). From 300mm up, it becomes challenging to handhold lenses on APS-C sensors. And then you also have the problem of focusing accurately.

The only problems that your images demonstrate are strong LoCA (visible in several shots, but best sample is on the grill of the Mercedes) and a muted color contrast, which is typical for Takumars. I doubt you have a bad copy.

Some tips for handholding:

- keep a fast shutter speed. For a 300mm lens try at least 1/500 until you get better with it
- brace yourself - hold your elbows next to your body, left hand closer to the front of the lens if possible, camera against your face
- lean on something if you can - wall, pillar, fence, whatever you can find will help
- control your breath. breath in, breath half of air out, then hold your breath and try to shoot in the next couple of seconds

Good luck!

maybe I should give this lens a shot.

I have a K5 IIs and works well with this lens. May be the real problem lies in the lack of in-body stabilisation of SD15. Crying or Very sad Crying or Very sad
