I had low expectations, but I've been pleasantly surprised. This lens has a lot of limitations, as have been previously stated, but like most lenses it performs very well when used within it's limits. Mine's the Vietnam version. It's plasticky, soft wide open, and the manual focus sucks--as one would expect with a lens this cheap. But its IQ is pretty decent, even on a K-1. Nothing special, but also not terrible. Actually, the colors are pretty realistic on a K-1, unlike other F and FA zooms I've tried on full-frame. But what's really nice about this lens is it's size and versatility. If it's a gloomy day and I want to shoot HP5+, and I want a compact kit, this lens performs very well. It has nice contrast and I can get plenty of sharpness from f5.6-f8. In that sense, it makes for a great travel/documentary style lens, especially on my MZ-3's. My Tamron 28-75mm f2.8 is undoubtedly a much better lens in nearly every way, but it's also significantly bigger. So the FA 28-70mm is a good compact alternative. To me, it's definitely a keeper. There's really no reason to use it on my K-1, unless I just had it in my bag and needed it in a pinch. In that case I'd be happy enough with the results. But this lens makes a lot of sense to have for my autofocus film cameras. The AF is fine, the IQ is good enough, it's easily replaced, and it's small and light. It's a very hand and pragmatic lens. It's unlikely to ever cost very much, so you really can't go wrong with it. | | | | | New Member Registered:March,2024 Posts:3 | Review Date: August 24, 2024 | Not Recommended |Price:$50.00 |Rating:3 | Pros: | Image quality is usable | Cons: | Build quality | Sharpness: 5 Aberrations: 6 Bokeh: 5 Autofocus: 5 Handling: 2 Value: 5 Camera Used: MZ-3, Sony A7RV | | So I got this lens to pair with a recently purchased MZ-3 (because I wanted an AF lens to test it), but ultimately tested the image quality on a Sony A7RV - probably a tad unfair I will say straight up that this is one of the cheapest feeling lenses I have used - including some kit lenses from Sigma, Tamron etc...Pentax definitely don't want you to manual focus this lens, but given it is designed to be AF I shouldnt be too harsh. On the MZ-3 the AF works as it should. The Zoom and aperture work reasonably well, if very cheap feeling. Given how cheap it feels the image quality is actually not THAT bad. I was expecting much worse. There is nothing to really stand out about it - as expected it is a soft wide open, but adorations are Ok. Its going to be fine on a film camera where you are only going to be making 4x6 prints, which is probably what Pentax where going for with this lens. | | | | Junior Member Registered:May,2023 Posts:173 | Review Date: May 29, 2023 | Not Recommended |Price:$40.00 |Rating:3 | Pros: | Inexpensive starter lens. Lightweight. | Cons: | Inconsistent focusing ability on auto . Washed out colors | Sharpness: 4 Aberrations: 4 Bokeh: 6 Autofocus: 3 Handling: 4 Value: 2 Camera Used: Pentax K70 | | Mine was made in Vietnam which May be the reason for poor performance. Japanese made version gets better reviews. I did read this lens may work better with an auto focus film camera. It performed poorly with my APSC K70 on auto. Gave it a shot for $40.00. Not going to keep it. | | | | New Member Registered:November,2013 Posts:17 | Review Date: November 7, 2022 | Recommended |Price:$30.00 |Rating:6 | Pros: | sharp lens | Cons: | strong CAs in the edges | Sharpness: 7 Aberrations: 4 Bokeh: 7 Autofocus: 8 Handling: 8 Value: 6 Camera Used: pentax k-5 k-x k200 k-s1 Fuji x-t100 x-e1 | | Why so many quite different test results and judgements about this lens? Hm? + Mines was sharp - O/- but had a problem with strong CAs, unfortunately ! So it was a disappointment for me. I'd sold it immediately. But some test photos here are really beautifull and without CAs. Why for ??? Were there different manufacturers of it ??? | | | | | Pentaxian Registered:April,2009 Location:Madrid, Spain Posts:11,376 | Review Date: April 1, 2022 | Not Recommended |Price:$40.00 |Rating:2 | Pros: | None | Cons: | Flimsy build and terrible image quality | Sharpness: 1 Aberrations: 1 Bokeh: 5 Autofocus: 8 Handling: 3 Value: 2 Camera Used: K-3 | | I bought this lens to use as a lightweight general purpose zoom to combine with a fast fifty for travelling when I take film gear as well as digital. Having read reviews that suggest it's a step up from a kit 28-80mm kit zoom I thought this would be a good option. I was wrong. I've tried a few 28-80ish film era kit zooms and in terms of image quality this is worse than all of them. All those kit zooms are at least capable of sharp results when stopped down to f/8 but this isn't. It starts off very poor at f/4 and improves to moderately poor at f/8. An absolutely useless lens, incapable of taking a sharp photo at any focal length or aperture setting. | | | | New Member Registered:September,2020 Location:Derbyshire Posts:3 3 users found this helpful | Review Date: August 21, 2021 | Recommended |Price:$80.00 |Rating:8 | Pros: | Sharp in the centre wide open, sharp across the frame from F11-13, decent design, great kit lens | Cons: | Inconsistent build quality, not a true 28mm at the wide end | Sharpness: 8 Aberrations: 7 Bokeh: 6 Autofocus: 9 Handling: 9 Camera Used: MZ5n | | I had two of these on an MZ5n. I used it with film and NOT digital. It was my first autofocus camera and first autofocus lens. I have nothing but good things to say about the lens with some caveats. I had two versions. The first was made in Japan and it took a photo in Norway that got printed in the UK's Amateur Photographer magazine in the 1990's. The second - bought because I thought it would be a good idea to have a back up - was made in Vietnam. It was different. It's colour rendition was cooler and it also exhibited vignetting. I sent it back. So, my first piece of advice is to get the Japanese version. I got the 28-70mm because Dr Stewart Bell of Amateur Photographer magazine tested it and expounded on its remarkable centre sharpness wide open and its relative consistency when stopped down and through the focal range. I used it for landscape and environmental photography. If you worked around where performance was best, used it within its limitations - you were rewarded with decent, sharp and nicely coloured pictures (one of the best films for this lens was Fuji NPS 160 - the detail rendered as well as colour still takes my breath away today). Slides were rendered just as well, with more contrast. This was a perfect enthusiasts lens. Just the sort of thing Pentax was good at - getting you off to a good start with your photography hobby. OK - the distortion was self evident but not that bad and at mid focal lengths (35mm - 50mm) you could make it just about disappear. You had to stop down a bit to use the tele end. Yes, the front of the lens wobbled a lot - it was not built as well as say the FA 35mm f2 AL. But goodness me, it was bargain and a bit of triumph design and cost wise. I've no idea how these have stood the test of time. I've no idea how they might behave on digital but until I graduated up to the primes and then the formidable 20-35mm zoom, this lens kept me going through the late 90's, early 2000s. If you get a good one, not too badly used, made in Japan and you're on a budget then check it out. | | | | Forum Member Registered:June,2014 Posts:62 2 users found this helpful | Review Date: August 17, 2021 | Recommended |Price:$16.00 |Rating:6 | Pros: | small, light, cheap | Cons: | soft, poor build quality | Sharpness: 6 Aberrations: 7 Bokeh: 7 Autofocus: 6 Handling: 8 Value: 8 Camera Used: K-S1, KP | | I bought this lens together with a broken camera and a bag (actually, I was interested mostly in the bag). As a consumer kit zoom of the film era, it looks and feels very cheap. My copy was made in Vietnam and is supposed to be optically inferior to the Japanese-made version. I tried it on the K-S1 first and almost threw it in the garbage not a single sharp photo! However, when I mounted it on my KP and did some AF adjustment, it was a different story. On the KP, this lens performs similarly to the 18-55mm kit zoom. It's very soft on the edges at the wide end but decent in the 40-70mm range if stopped down to F8 or higher. Not good for landscapes but OK for indoor shooting. The focal range on APSC is inconvenient, neither wide nor tele. This lens is definitely not good enough for the K-1. I can recommend it only for those who shoot film and scan no larger than 6 megapixels.

Some people say that is made of plastic, but actually it is made of metal and has a grey plastic looking finish. It is a better lens than the ones from the SF-series, which also had a plastic look due to the finish used. It is still like new although much used on the MZ-5. On the Samsung GX-10 it was dull, but on the Pentax K3II it works great with natural colors. Its autofocus is very fast bearing in mind that it is a screw AF. And I own the early version of this lens released at the same time as the MZ-5. The metal used is quite thin compared to the old lenses like Pentax F3.5 35-105. I had to rediscover this lens as it did not work well with my early digitals, but is does with my K3II. But in all those years never had problems with it, it has still the same smooth zooming and although the manual focus ring seems small, just like on the AF lenses from the SF period, it works great. And of course Pentax engineers anticipated that you would use AF most of the time and only in emergencies turn to manual. But I never used it, neither will I use the manual override of the digital era lenses. Although I will use it now, because it has such a nice macro capability, that can only be used with manual focusing. It did not work well with a film camera, but it does with a digital, because you are able to instantly the result and can adjust if needed. Highly recommended this lens, I would say. | | | | Loyal Site Supporter Registered:October,2018 Location:Quebec City, Quebec Posts:7,535 2 users found this helpful | Review Date: December 5, 2019 | Recommended |Price:$60.00 |Rating:9 | Pros: | Very sharp, inexpensive, useful focal range. | Cons: | Feels too plasticky, despite having proven reliable. | Sharpness: 9 Aberrations: 8 Bokeh: 8 Autofocus: 9 Handling: 10 Value: 10 Camera Used: Pentax K5 | |
This lens is much underrated. It looks flimsy but has proven to be quite durable over the years | | | | Junior Member Registered:January,2018 Posts:47 2 users found this helpful | Review Date: November 18, 2018 | Recommended |Price:$50.00 |Rating:8 | Pros: | small size, sharpness | Cons: | focusing | Sharpness: 9 Aberrations: 8 Bokeh: 8 Autofocus: 6 Handling: 8 Value: 9 Camera Used: K-1 | | I think this is a pretty nice lens for the money. I do have the DFA 24-70 which is superb in IQ and I am used to how it handles and focuses, so clearly this old $50 lens does not perform equally. I have shot video, landscapes and some portraits with this lens and this is very much acceptable in all this. For video, you can still control DOF and f/4 does not make it too narrow either. (Of course there are limitation with K-1 autofocus and an old lens like this, so f/4 allows for some target movement). The portraits i.e. close focusing distance at large apertures, are good without any major issues. Again, this is not a $1000 pro lens. For landscape shots, stopped down to f/8, I cannot really see the lack of detail some earlier reviewers are seeing in their lenses. The only actual drawback is that it is sometimes a bit challenging to make the AF lock in low-light situations (especially when focusing close). For daylight use, there is no issue. Summarizing, this lens is a good budget walk-around lens when you do not want to attract a lot of attention (like you do with a DFA 24-70). | | | | Senior Member Registered:April,2012 Location:Endeavour Hills, Victoria, Australia Posts:211 1 user found this helpful | Review Date: August 22, 2018 | Recommended |Price:$100.00 |Rating:9 | Pros: | Nice balance of contrast, good colour | Cons: | Speed | Sharpness: 8 Aberrations: 8 Bokeh: 9 Autofocus: 9 Handling: 10 Value: 10 Camera Used: K-1 | |
I used this in Japan for a short while, just interested to see how it would go. I liked it a lot. It is quite sharp, without being stunningly so. Worked fine with the K-1. The attached photo was taken in Tokyo. I was interested in the lines of the scene and was trying to get some elements in focus, but not all. https://photos.app.goo.gl/5WUq4W7q3AqyJy6c7 | | | | Veteran Member Registered:July,2007 Location:North West UK Posts:390 2 users found this helpful | Review Date: March 19, 2018 | Recommended |Price:$25.00 |Rating:7 | Pros: | Small, cheap, low CA | Cons: | Soft, very loose focus ring | Sharpness: 6 Aberrations: 9 Bokeh: 8 Autofocus: 8 Handling: 8 Value: 8 Camera Used: K-1 | | This could have been the go-to lens, but it lacks detail. Think about it, a very small 28-70mm F4, yes F4 thoughout the range and handy for, say, travel. But, it is soft. Not overtly soft, but with the demands of a 36MP K-1 it is lacking. The detail is not really there. You say, "well that is not surprising with an old lens". However, I have primes twice as old that provide so much more detail. Then again, it is a very small lens for something that could provide so much with its specification. Is it bad? Reality is no. It is - okay. CA is surprisingly good, as is contrast. It is just that light transmission from the optics that could be better. Also, the zoom ring is very slick, lacking some sort of smooth friction that we love. On the upside, it was VERY cheap, at £20. so I can't really complain. But the potential of a similar F4 28-70 is certainly there brand new, weather sealed and silent motor. If Pentax can make such a tiny F4 lens (my mates Canon 24-70 F4 is at least twice the size if not more), then we may be in luck. If you find one, never pay top dollar, get it for the price of a few beers, and have fun with it. The size and F4 is worth giving it a go just for the fun or it. | | | | Veteran Member Registered:July,2009 Location:Minnesota Posts:1,520 3 users found this helpful | Review Date: July 31, 2017 | Recommended |Price:$90.00 |Rating:8 | Pros: | Better than similar lenses | Cons: | Build quality, soft on long end | Sharpness: 8 Aberrations: 9 Bokeh: 7 Autofocus: 9 Handling: 9 Value: 9 Camera Used: K-3, K-01 | | To some extent, this lens has been down-rated due to the low quality of plastic, and internal optical failure (separation) on some copies. Purchasing unseen is not advisable unless assured of return at no cost. As a kit zoom from the film FA era, expectations should be relatively low. Optically, a good copy's sharpness isn't considerably different than the 18-55 - probably this lens is sharper in the corners, but not quite as sharp at center (as would be expected given the image circle difference). If you like the saturated lower contrast film look, this lens has it. Colors are very pleasing. Screw drive AF works fine, and isn't as noisy as some others. The lens is pretty soft at the long end, probably not reaching "good" until f/8. The rest of the range is OK from f/5.6. I had a similar style Sigma that was optically inferior in every way. It will work fine as a casual portrait lens, and for street photography where normal to portrait length is desired. Keep in mind that this lens is smaller and lighter than a Ltd. 20-40 which is pretty amazing for a constant aperture lens at 2.5:1 zoom ratio designed for FF film. | | | | New Member Registered:September,2016 Posts:3 1 user found this helpful | Review Date: April 8, 2017 | Not Recommended |Price:$35.00 |Rating:3 | Pros: | Small and lightweight | Cons: | Cheaply made | Sharpness: 4 Aberrations: 4 Bokeh: 3 Autofocus: 9 Handling: 2 Value: 4 Camera Used: K-30 | | It's main asset is the handy size and the fast and accurate AF. Everything else just screams "plastic crap". It's probably the most cheaply made lens I've ever used. Compared to another constant f4 zoom, the 16-45, it's ... well there isn't any comparison actually. It's soft soft soft at f4 and I personally I find the colors washed out and dull. I've used the following overlapping zooms on my K-30 and optically I'd rank them in the following order: Pentax-A 35-105mm F3.5 Pentax-DA 16-45mm F4 Sigma 18-50mm F2.8 EX DC Macro > > > Pentax-FA 28-70 F4 Avoid unless you get it for free. Sold it very soon after getting it. Disclaimer: might've gotten a bad copy since some reviewers seem to be fond of it. | | |
