Hi, I don't have that lens, and I hope someone who has it can chime in and answer.
I will only say that I have the 80-200mm f/4.5 first series - same period more or less - and the focus throw is about 180░, which can be a little long and uncomfortable if you need to focus on moving subjects.
If the 75-150mm is similarly built then I expect it to have a long throw...

Thanks for the reply. I also have the 80-200mm lens. I prefer a throw of about 120-180 degrees. I don't photograph moving subjects, hardly ever, so a long throw isn't a problem. I have a Vivitar 28-85mm lens, and although being a superb piece of glass, alas, it's focus throw is much less than 90 degrees! MUCH less! Probably closer to 45-50 degrees! Being a manual focus lens, it makes for some very difficult fine focusing!

Yeah I agree longer throw helps but not always - moving subjects are harder to track with too long throw. Also video is challenging, but out of two I would always pick too long throw rather than too short one. Probably best lens for manual focusing in this range is SMC-A 70-210 f/4 - not only great colours and contrast, great range but also nice long focusing throw around 180 degree and additional 20 degree of macro range. Excellent push pull design that will always be preferred for quick zooming/focusing + target tracking is much easier for video. Not to mention the convenience of 'A' setting

EDIT: of course if bulk is an issue then 75-150 will always be the winner for its great optical quality and range in relatively small and light package.

It's funny that you should mention these two particular lenses! I have both of them on their way to me as we speak. I bought the 75-150mm and a Pentax-M 50mm, f:2 tonight in a package deal on eBay for $50.00 plus $11.00 shipping. The other.... the SMC-A 70-210mm is due to be delivered tomorrow. I'm looking forward to a fun weekend! I'm excited about the macro (close focus) capabilities of the 70-210mm. The 75-150mm sample photos were what really sold me. Extremely sharp.

I love candid so im ok with 100mm FOV on APS-C.And this len so small that i bet every one(not pro)think it is not a telephoto len.

Looking forward to get M85 but that is another story,im about to spend more time with M50 and M100 first!

M100 f2.8


M50 f1.7

Yeah, it has its uses, it's just not much of a walkaround lens.
If it was only about its optical qualities, it would be my favorite lens, bar none.

I'm looking forward to see you comparing the two! I have the A 70-210 and have considered the 75-150 but don't know if it's worth the overlap. I've thought about the Vivitar Series 1 70-210 2.8-4 as well

Are there so many good lenses in M series, or it's just a bunch of good photographers here? Now I want more M lenses from last pages.

Which is which?

My Pentax SMC 70-210mm, f:4 came today. A very clean lens. A little "something" inside the front element, but nothing I can't live with. I took some test photos with it and was quite pleased. Yesterday, I received a Vivitar 70-210mm, f:4.5 lens (Not a Series 1) I paid $12.00 for and also took some test shots with it. See if you can tell which is which?

I wouldn't know, but the second one shows a fair bit of longitudinal CA and purple fringing, while the first doesn't show this so much. However the closer focus distance in the second one would tend to magnify that. Colors also seem distinctly cooler in the first one.

I like the first one better.
Edit: Duh! Pentax is the first because there's the aperture tag in the EXIF...

I prefer the colors in the first one, which I guess it is the Pentax one !!
