| Pros: | Lightweight, Constant aperature, sharp | | Cons: | a tad soft beyond 135mm | |
To be fair, I have to give this lens a 7, although my copy came to me off ebay with a fair amount of dust on the internal elements. Still, this is an excellent and lightweight travelling companion for a Std-Tele zoom. OK, maybe it is 2x as heavy as the DA 55-200, but in it's defense, it is a constant aperature design, and manual focusing is a delight with this baby, and, at f4, it gains a stop at 135-150mm on the DA 55-200 , which comes in handy indoors. My only gripe, and it is a minor one, is the minimum focusing distance of 1.2m, but it only gives up 0.1m to the DA 55-200 here. If you can find one, snap it up & save a few bucks, enjoy the smooth MF action. | | | | | | | | Review Date: Mon February 12, 2007 | Would you recommend the lens? Yes |

Purchased this clean lens on eBay. First test showed good optics with good color rendition. It is well build, fairly lightweight. I tested it on a K10D and compared results with a 50-200mm. Sharpness was just as good. | | | | | JMNKet

| Pros: | Sharp, solid, and well built | | Cons: | Heavy compared to modern lenses, limited range | |
This was my first all manual lens and what a treat. Great sharpness and overall rendition of the scene. Surprising how easy it is to use. Usable at f4 no problem and works nicely for tight portrait shots. Consistent quality at 75mm and 150mm and everywhere in between. Sure, it's heavy but the feel is very reassuring and it doesn't take long to get used to. | | | | | 8540tomg

| Pros: | Fairly light, sharp and contrasty | | Cons: | Fully manual | |
I’ll preface my comments by saying I’m not a big fan of zoom lenses. I prefer primes for almost every application. Prime lenses are almost always faster, lighter and optically superior at their designed focal length. Zooms of this vintage, while arguably more versatile, tend to be big, heavy and slow unless they are very expensive. It is a personal preference and I don’t want to dredge up the old prime/zoom debate.
Bearing this prime prejudice in mind I found the Pentax M 75~150mm provided a range of very useful focal lengths for my film cameras. It balances beautifully on my Pentax MX as well as the K10 digital. I don’t find the lens to be heavy at all. It isn't overly fast at f 4 but it still produced some very good images for me. I found it to be sharp and contrasty even wide open. The lens exhibits typical Pentax build quality which is to say it is very good indeed. The built in lens hood is a nice touch. Boz Dimitrov provides further technical details:

On a digital camera the M 75~150mm's fully manual nature presents some limitations. On my K10 one is required to manually indentify the focal length for the camera to function properly. To simplify things I usually just compromise and set it in the middle of the range and hope for the best. To tell the truth it is a pain in the ass. It is yet one more reason I prefer prime lenses to zooms especially vintage ones. I am rating this lens as 7 out 10 for use on a film camera. This is, after all, the format the lens was designed to be used in and it is in this format it should be evaluated. It would be unfair to compare it to a modern digital zoom. It will serve you well in this format and a decent copy may usually be found on EBAY for well under $100. On digital I find that while you can make it work and get good results it is just too much trouble to be bothered. | | | | | 123K10D

| Pros: | Superb build, smooth focus/zoom. | | Cons: | Minor CA | |
This zoom is 'prime' quality, from 75 to 150. Sharp with great contrast even wide open. Classic Pentax SMC M rendering of images. It's great to be confident with a lens, no matter where it's zoomed and what's its f stop is. At f5.6 + , this is as sharp as any Pentax 50 I've had - including the best one I've ever had, my current M 50 1.7. | | | | | leopold

At first i didn't like it because i didn't find it sharp enough.But after some testing i found that i was wrong,it's very sharp at any F-Stop and focal length.I'm now using it with Ext. tubes and Pentax TC 1.4X-S with very good results on my DS2.
Certainly a very good zoom to add to a collection! | | | | | aLpi

This is an excellent lens, rendering superb images. Its compactness makes it ideal for street photograpy or those situation when you don't want to be seen. The build quality is good and the focus is silky smooth. A constant aperture of f/4 makes it that much more special. | | | | | Indianadinos

Nice zoom, very well built, as most of the P-K and P-M lenses. Only issue: it is not an P-KA lens, so you cannot switch the f/stop value using the camera handle ... | | | | | nobbsie

| Pros: | build quality, constant f/4, sharp wide-open, pleasing bokeh, smooth focusing and zooming, | | Cons: | it's not an A lens (stop down metering only) | |
This is one of the hidden jewels in the Pentax lineup IMHO. Wonderful build quality like all M lenses with smooth, well dampened one-touch zooming and focusing. The built-in hood is a nice touch.
Overall IQ is great with very-good sharpness wide open and pleasing bokeh although purple-fringing can be a problem on very-high contrast edges.

| Pros: | Very sharp. Very light & compact. Excellent build: metal barrel, great manual focus feel, & built-in hood. Decent close focus ability. Takes 49mm filters. | | Cons: | No "A" setting | |
This is a lens with prime lens quality, very sharp even wide open. IMO, on my K10D, it is sharper than SMC-A 35-105mm F3.5 in comparable apertures & focal lengths. It is even sharper (or easier to get sharp pics) than my DA* 50-135mm F2.8 (manual focus, of course). I have tried these 3 lenses many times. The 75-150mm is the one that most consistently gave me sharp pics.
The manual focus feel is also the excellent, light and smooth. This lens is compact & light. I just wish it had the "A" setting. | | | | | |
