Pentax 55-300mm f/4-5.8 ED SMC DA review by kiwijono
Review Date: 2/8/2014 Would you recommend the product? Yes | Total Spent: None indicated| Rating: 8 

Pros: plenty sharp, not heavy, surprisingly rugged
Cons: Could be faster

My version is actually the DA-L variant which is largely the same (identical optically) except for having a plastic mount and not coming with a hood.
I might as well start out by saying - I like this lens.
I got this in a K-x kit and so far I have taken a lot more keepers with this lens than I ever did with the 18-55 kit lens. Also have some older lenses like Super Tak 200 f4 (which I like) but keep coming back to this lens for its shear convenience with decent IQ.
I find mine to be decently sharp - particularly at f8.

A month after I got it, I had a dumb incident with my camera falling out of my camera pack (don't forget to close those side flaps!!!) 2 feet or so on to concrete and it landed on the 55-300 lens. I was very distressed as usually I'm so careful. Can't believe it but there was no ill effects (mechanically, optically or cosmetically) to the lens or camera - not even a mark!

Pentax 55-300mm f/4-5.8 ED SMC DA review by kh1234567890
Review Date: 1/30/2014 Would you recommend the product? Yes | Total Spent: $350.00| Rating: 7 

Pros: Good contrast and reach, price
Cons: Size, weight, no WR

The 55-300 feels bulky, heavy and since fully extended with the hood on it hits some 23cm in length it also feels long. Not being into birding, this matters to me - it is hard not to be conspicuous with this lens on your camera.

AF can be noisy and slow but that is the price you pay for a long spin on the focus ring which actually makes it possible to accurately focus manually (no damping of course because of the AF). Performance-wise it is good but not significantly better than the 50-200mm. There is little CA or vignetting and very little purple fringing - what CA there is does vary with focal length, becoming quite noticeable at the long end. Bokeh is very pleasant and sharpness is good, as is contrast and colour.

Manufacturing quality control is abysmal - my first sample was badly de-centered. So if you get one and aren't happy with it throw it back at whoever sold it to you, the replacement might be better.

I like to travel light and hence I still prefer the DA50-200 to this one.

Pentax 55-300mm f/4-5.8 ED SMC DA review by Tord
Review Date: 4/3/2013 Would you recommend the product? Yes | Total Spent: $500.00| Rating: 8 

Pros: Light weight, fast AF (on K-30)
Cons: Plastic feel

My wife bought this lens quite a while ago, to be used with her K-5, where it proved to be surprisingly sharp in the long end (not a common trait for telezooms), but not that fast.

That changed with the purchase of the K-30, that really boosted the lens's capabilities.

High recommended, although a very plastic lens ;-)!

Pentax 55-300mm f/4-5.8 ED SMC DA review by aesace
Review Date: 8/25/2009 Would you recommend the product? Yes | Total Spent: $300.00| Rating: 8 

Pros: Optical quality, build quality, focus range
Cons: slow AF

I replaced old Pentax F 100-300 4,5-5,6 with this new Pentax 55-300. The optical quality is very nice also on 300mm , low CA, good in backlight, but the AF speed is very slow even in comparison with the old Pentax 100-300.
Anyway I like this lense for the great focus range and optical quality.

Pentax 55-300mm f/4-5.8 ED SMC DA review by ayast
Review Date: 5/28/2009 Would you recommend the product? Yes | Total Spent: $330.00| Rating: 9 

Pros: sharp, light
Cons: a bit soft at the highest appertures

I have actually [partially] replaced a Sigma 105mm macro (a great lens) with this one. It is such a surprising product. I chose it based on reviews (not on this site, which I began consulting later), but I feel it is underappreciated. I am not too crazy about sharpness at the highest appertures and was rather disappointed with it at first when using Sv mode on k200. I would set it to high speeds for bird shooting and the camera would set it to F5.8 at 300mm thus getting subpar results. But then I tried Av mode and starting from F7.1 and lower this lens becomes an excellent performer. Highly recommend it!

here are some sample shots:

Pentax 55-300mm f/4-5.8 ED SMC DA review by joekashi
Review Date: 9/4/2008 Would you recommend the product? Yes | Total Spent: $349.00| Rating: 9 

Pros: sharp at most focal lengths

This is an excellent lens for the money, generally sharp and contrasty at 200% at all tested focal lengths, including 300mm. I found it to be much sharper at longer focal lengths than the Pentax 50-200 and the Tamron 70-300 tele zooms that this lens replaced. It is small and light, given its reach. I did not give it a 9 for construction because, as expected, it is mostly good tight plastic. Plastic lens construction, no matter how good, is not in the same league as the traditional metal lens bodies of the 35mm era.

Pentax 55-300mm f/4-5.8 ED SMC DA review by jamesm007

Pros: Sharp at 300mm f5.8, a bit smaller that it rivals, good control of CA/PF
Cons: A little expensive compared to it rivals, but worth it.

I have owned the Tamron and Quantaray 70-300mm lens, they had too much PF for me. I bought the Sigma 70-300mm APO instead. The Sigma was fine but for its softness ~300mm at all but the highest f numbers (over f7). The Pentax 55-300mm is very good at 300mm f5.8 peaks at f11, and go down just a tad lower at 270mm and it peaks at f8, this is fantastic performance for a consumer zoom lens. This lens is sharp and usable wide open from 55-300mm! This lens has much better control of CA/PF over the Tamron, not as good as the Sigma APO, but its not a problem and I never have to deal with it in PP. Of course the Pentax lens is more expensive than its rivals the Tamron/Sigma lens but well worth it. This lens has exceeded my wants for a consumer telephoto lens by a good margin and is my favorite lens. You can just put this lens on your camera and shoot at any aperture and focal length with sharp results. Its sharper than the Sigma or Tamron and has very good CA/PF control, as well as being smaller and lighter, How did Pentax do it? Highly recommended.
