| | Looking for a new walk-around zoom, I saw this lens for sale for cheap on kijiji. Doing a little research showed that this lens is a bit of a hidden gem for its price, reported as being consistently sharp over all ranges and even getting in spitting distance of some vintage primes, according to some MTF tests I dug up. I also liked the 9 blade design which is rare on a Pentax zoom. I took the plunge.
Having only shot a few rolls through it, I can already say its just as good as I'd hoped:
- At 70mm, it's sharper and faster (f4 vs f4.5) than the much-loved F35-70 with equal colour.
- At 135mm, its much sharper and faster (f4 vs f5.6) than the F35-135 with much richer colour. the 35-135 has a yellow cast that I hated and this corrects that while adding a certain punch to reds
- At it's macro setting of 210, it takes more pleasing pictures than either of my previous lenses at their respective long ends.
I don't go crazy over bokeh, but I will say that it looks every bit as confident as my FA43 Limited--maybe even more. The 9 blades really do smooth OOF elements a lot.
Simply put, its the most consistent performing zoom I own across all zoom and aperture ranges and I'm surprised it doesn't get more love on forums.
Now, the bad: it's a big ol boy. Or at least feels that way given it's dimensions. You definitely feel it when you're shooting it, but all that glass seems to be going to good use, so it's a small complaint. The AF feels overly aggressive too... like the camera is tearing the lens apart! But a minor gripe considering the optical performance.
TDLR: Get it. It's one of the best pantax tele zooms for the money. | | | | | Site Supporter Registered: December, 2015 Posts: 5,404 3 users found this helpful | Review Date: May 15, 2022 | Recommended | Price: $50.00

| | I find ratings like this very hard to choose a value. For example, Autofocus. How do I rate this? Compared to a PLM? Compared to another screwdrive? Compared to modern MILC? And isn't AF also partly the cameras responsibility as well as the lens design?
So I will just leave a series of images on my Blog that are lightly retouched jpgs to help you get a better idea. Really for me, lens performance these days becomes less and less important. I think a good photographer should be able to make any lens perform much better than expected. If we're scrutinizing a lenses traits then it's probably for very specific case usage and you'll already know from reputation if that lens will do what you need of it. For me this is a cheap affordable lens with acceptable IQ. https://www.eddysummers.com.au/blog/becs-garden-with-the-pentax-f70-2104-56 | | | | New Member Registered: August, 2017 Location: Ronneburg Posts: 1 1 user found this helpful | Review Date: August 11, 2021 | Recommended | Price: $60.00

| | Ugly body but as compensation excellent Optics.
Good old school screwdrive. A little loud and hunting the focusing in lower light situations.
But it isn't a speed lens and that fact doesn't bother me.
In normal daylight situations the AF works well at my K-3.
I think it depends of the camera.

| | I use it only in manual focus for landscapes with F8 and higher. The zoom ring is hard to turn at short end, AF ring is horrible - very small and clumsy. Also the front element rotates which makes using filters a nightmare. The lens is small and lightweight comparing to modern lenses and it was incredibly CHEAP :-) IQ on the other hand is impressive. The images are very sharp at F8-F16. I do not know much about bokeh and aberrations as I only use it for landscapes. Do not use AF, it is not reliable. The price/value ratio is very high. And it doesn't need much room in your backpack.

| | Such small size for the zoom range . 49mm rotatif front element. First mount on the k1 ... quite loud af system but acceptable and really fast af !
First time use i was afraid...As I have a mint copy of a F star 300mm 4.5
But after somme pics.....damned !!!!
Except for low light and action (no pentax lens existing for action for me) Its really good with the k1 and the size is very Nice so you can bring it with you each Time . I love my fstar but i still find it big to bring it with me often.
Quite the same size and weight than my k135 f2,5.
F4 Po fully usable at 70mm, one or two stop after po Everywhere (F8 at 210 really sharp !!!) and its a real good Lens. Better than my da55-300 on k5. I always hated this da plastic zoom with such a poor and loud af system...this f70 is much better , faster and less loud and much better feeling handling
Nice Bokeh, contrast, Colors. Some few AC but easy correction Very underestimated zoom and extraordinary bargain for the price. No wr, dont CARE...60€...
With a fa 20-35 , a fa50 2.8 macro and this zoom you have a good light allround kit with your beloved quite heavy k1 …. And sometimes i will add my fish zoom f 17-28 too ;\…
Try to find a good copy (old...) . If not sharp you found a lemon, no way so try again | | | | New Member Registered: February, 2020 Location: ATX/DFW Posts: 12 1 user found this helpful | Review Date: May 18, 2020 | Recommended | Price: $20.00

| | To preface, I don't have massive amounts of experience with quality modern Pentax glass, as I'm pretty attached to legacy lenses.
I got this lens from a fellow PF user for only the cost of shipping due to a bit of haze, so that could partially impact my sharpness rating. For $20, it's a deal I couldn't pass up, and I'm glad I took it. On crop, this pairs excellently with the SMC-F 35-70 for a good all round kit if you don't need wide angle. In typical Pentax fashion, the colors are wonderfully rendered- greens in particular are really beautiful. I'm not much of a pixel peeper, so the sharpness is just fine for me. Not the sharpest, but it's definitely usable. Some aberrations and fringing in high contrast areas that can easily be corrected in PP. Like the 35-70, the front element rotates, and the autofocus can be downright VIOLENT and of course loud, but it's pretty quick. Required a bit of calibration on my K-S2. Manual focus is eh, not much feedback and tiny focusing ring, but it's fine if you're using focus peaking in live view. I'll be taking it back out to motor racing events once we get past the current global situation, looking to see how it performs at an F1 weekend later this year Plasticky build with a polarizing look, but I'm personally a fan of it with the white and grey body of the K-S2. Some images below. Weird lines in bokeh in some of them because I was shooting through a wire cage, but the first image is an example of some of the really nice circular bokeh possible.
2022 update: she went with me to the F1 race this year, and did better than I expected VERY happy with this $20 wonder [/url] [/url] [/url]

Pros: | Not sure there are any | Cons: | Heavy, very noisy AF, poor image quality, hit-&-miss AF, very ugly | | I bought this lens in order to have a compact telephoto zoom that I could use on both film and digital, especially for travel. The first problem is that this lens is too heavy to travel with. The second is that image quality is poor, though I suspect that's largely because the autofocus is very hit-&-miss, with a considerable leaning towards "miss". That second problem would be enough to get rid of it even if every other aspect of the lens were perfect, but they're not. Aside from those two issues the lens has very noisy auto-focus, which from what I gather is quite common on F series lenses, and it has looks that only a mother could love.
I always post reviews of lenses with sample pictures but not this time - I don't have a single one that was good enough to merit uploading anywhere.

| | Handheld K10 + F 70-210 mm Handheld K3 + F 70-210 mm. My copy is pristine as I am very choosy and I take my time when I buy on eBay. The F series was plasticky and focusing might be somewhat loud. Personally, I'm very satisfied with its image producing performance. Most of the time, I shoot landscapes on a tripod and I use the optimal aperture range (f/8 to f/16). On an APSc sensor, it is equivalent to a 100-300 mm lens and is VERY SHARP, with good contrast and beautiful colors. It even performs like a champ on the K1, proof of its excellent optical quality. You can't go wrong with this awesome, ridiculously inexpensive lens. If you cannot put it to good use, find another pastime ...

Not bad in the long end but not spectacular. As is typical of this type of lens, as the barrel goes longer the lens gets less sharp. 2018-F-70-210-210mm-woodpile by Norm Head, on Flickr

It is noisey and when it locks focus it will almost break your wrist with a loud "ka thunk", but if you're looking for a budget lens it's one of the best. I doubt you'll find a better FF telephoto for the price.

| | While saving money for a DFA* 70-200 F2.8 in the near future, I'm using this Pentax-F 70-210 lens on my K1 as a temporary low cost solution.
It serves as a kind of 'filling the gap lens' for my beloved FF prime lenses (FA 50 1.4 and FA* 200 2.8).
For a Pentax-F lens produced in the 35mm film era about 25-30 years ago, the image quality is very decent.
Considering the price ($30) I paid for it, I'm more than happy with it.
Here are examples taken a while back with my K5:
Taken at 135mm, F8. https://www.flickr.com/photos/65545813@N07/32386742064/in/photostream/
Taken at 210mm, F10. https://www.flickr.com/photos/65545813@N07/33181056981/in/photostream/
Taken at 210mm, F10. Bokeh is quite nice too. https://www.flickr.com/photos/65545813@N07/33230976555/in/photostream/
For me, the main thing I don't like about this lens is its rotating front element (while focusing) which make the use of a CP filter impossible.
I bought this lens as part of 3 lenses listed below, paid €110 for the lot, worth every cent to me!
SMC Pentax-K 85mm F1.8
SMC Pentax-F 24-50mm F4
SMC Pentax-F 70-210mm F4-5.6
Therefore, the estimated price of $30 for the Pentax-F 70-210mm.
($40 for the Pentax-F 24-50mm and $50 for the Pentax-K 85mm)

| | This is a good entry telephoto lens with a couple shortcomings. I have found the ideal application for this lens is portrait type photography. This lens is simply not useable for sports, wildlife, or landscape pictures because it lacks infinite focus (at least my copy) with a maximum focusing distance of a paltry 20 ish meters. The other major shortcoming is the poor plastic construction of the focusing ring (which is tiny by the way). I also had the front element fall out of the lens, It was luckily on grass and screwed back in later that evening. I will give a couple of good examples of where this lens shines. All photos were shot RAW and contain no lens corrections in lightroom to provide acurate samples. Most have been taken one stop from wide open. Take in mind any compression due to these photos being a web upload.
This picture was taken at F5.6 at 100mm, The original file was very sharp, with the glasses and hair clearly defined.
This picture was taken at F5.6 at 70mm, another sharp picture with good details.
This picture was taken at F5.6 at 70mm, good depth of field with out of focus details rendered smoothly. Pretty Sharp as well.
This picture was taken at F8 at 210mm. This was where I found out this lens lacks infinite focus, I could only capture images when the players were only feet from the sideline.
Even if you take into account where this lens can not perform, It is still worth the buy. This lens is an incredible value at $56. I have seen it listed for more, sometimes even over $100, but I would steer clear or buy something more versatile and well built. I would totally recommend the purchase at around $50. This has been a great lens to add to the collection, a definite 7-8/10.
