Work in low light and capture images with exceptional "bokeh" with the 135mm f/2.0 ED UMC Lens from Samyang , available here for Pentax K mount full frame & APS-C cameras. This all-manual telephoto prime offers a flattering perspective well-suited to portraits and other sensitive subject matter, and the fast f/2.0 maximum aperture helps ensure the image will be bright and have an extremely shallow depth-of-field. Also, this lens features one extra-low dispersion element to reduce the impact of chromatic aberrations in the final image as well as an Ultra Multi-Coating to reduce flare and ghosting.

A large manual focus ring as well as a physical aperture ring are available on the lens barrel for making smooth, deliberate adjustments. Also, this lens has a minimum focus distance of 2.6' and a front filter thread diameter of 77mm. Assisting with smooth, pleasing out-of-focus elements is a circular 9-blade diaphragm. Additionally, it comes with a removable lens hood and soft pouch.

Optical construction of 11 elements in 7 groups
Front filter thread is non-rotating for easier use with certain filters, such as circular polarizers and variable NDs
This lens features a mechanical aperture coupling that permits the use of aperture priority and automated exposure modes, as well as the ability to control the aperture setting with Pentax DSLRs

Best Investment Ever! A Vac-Mop!!!
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
These are replacement tools that fit our multipurpose vac/mop. This product is the most helpful and productive item we own. My daughter and I are free to do other things while Miss “B” is busy cleaning our floors! Such a backsaver! The floors are cleaner than manually sweeping and mopping them ourselves! It doesn’t get any better than that!

This is a Yes!
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
I needed to change out my Dreame vacuum accessories but didn’t want to pay the huge amount for the name brand kit, this works beautifully and fit perfectly. I cannot tell a difference and it lasts just as long as the original!

Seems complete…
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
I haven’t actually used this kit yet, but it appears to be very complete. The price is good and based on what I see at this point, I would purchase it again.

Good fit and quality - careless packaging
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
OK - I'm happy with most of the kit. The dead corner brushes are crammed into small bag and bent out of shape. It looks like 2 of the 6 in the kit I received might be usable. Since I can get 3 of these for the cost of the OEM kit, I suppose I'm still ahead of the game, but it would be nice if a little more care was taken in the packaging.
