Excellent mid-range telephoto zoom


Bought this used. My K-5 Pentax is not noted for autofocus, so I was surprised as to how much better it focused with this lens. I really love a fast lens. Worked great shooting a christening in the a dim light of a church. Great for low light candid shots. Used lens was better than rated. Lens hood was not included, but Adorama sent one later after I called Customer Service. A true measure of a company is not just price, but service == Adorama can through for me.


Great Lens!


Just used this lens on vacation and it was great. Is not too heavy, focuses true, awesome contrast. This lens might never leave my camera. Easy to hold and quick shift focus.

Awesome Lens!


This is an AMAZING lens... I love the wide rubberized zoom ring, which functions very smoothly and it has an internal focusing system (IF) the front element does not rotate so you can easily use a polarizer on it. The AF accuracy is excellent when approaching the focus point from farther focused distances, less so from closer distances. But see for yourselves...

Happy with it


Really nice and clear photographs, it does focus somewhat slow but not too bad. The range is great, personally would prefer something like a 200 but that is just me. Where I was most happy with this lens was at weddings, I was really happy with it's performance especially outdoor weddings, since indoor autofocus in low light is not good at all, but that is probably the camera.

my favorite lens


This is by far my favorite lens...the DA* lenses are great and I also have the companion to this lens (Da*16-50) as well. The lens has a great solid build quality as do all the DA* lenses as well as being weather sealed. The lens gives me crisp quality images thru out the zoom range and wonderful bokeh. I primarily use this lens for the weddings and events I am working but it really stands out when I am covering college sports at night or in the arena where you cannot use flash photography, thats when the f2.8 aperature really comes in handy.

Disapointed considering the hype


Being a Pentaxian I had great hopes for this lens. Considering the ratng and the hype I was very excited to buy this. Expecially since I am shooting both a K-7 and K-5 bodys. This lens failed over and over again. I sent it in to Pentax for warranty service 2 times and each time they found nothing wrong and sent it back. Finally I gave up and traded it in for a Sigma f2.8 70-200mm HMS lens. Much happier with Sigma.


Get one!!


Without any doubt, this is the best lens for Pentax DSLR. Sharp through all range, superb bokeh & 3D effect, lightweight, excellent build quality with weather resistant. All in all, perfect lens for most occasions.


Wonderful zoom


perfect mechanic & IMQ.A outstanding zoom in APS-C system.

One Great Lens


I am extremely pleased with the Pentax SMCP-DA* 50-135mm f/2.8 ED. It is a great lens. I love the Bokeh. Image quality is superb. I like the fact it is water sealed, I use it with a K20D and K5 both of which are water sealed. I do a lot of photography on whitewater rivers while rafting and this is a necessary feature also living in Western Oregon I spend a lot of time in the rain. The aspect of the lens I am most happy with is the auto focus. My non star lenses have great image quality but the auto focus can be a bit tricky and I spend a lot of time in manual focus especially when shooting through trees which happens a lot. This lens handles it very well and will focus on a subject on the far side of thick trees which the other lenses would not do so I never really have to take it out of auto focus mode. I would reccomend this lens to anyone who wants a professional quality lens.
