The 135mm f/2.0 ED UMC Lens for Pentax K Mount from Rokinon is a manual focus telephoto prime lens useful for portraiture and all medium telephoto applications. Its fast f/2.0 maximum aperture is effective in low light and enables shallow depth of field control. With a rounded 9-blade diaphragm, shallow depth of field imaging will be rendered with pleasing out-of-focus highlights. On Pentax APS-C format DSLRs the lens provides a 35mm focal length equivalence of 202.5mm. Its minimum focus distance is 2.6'.

The optical design includes one extra-low dispersion lens element to control chromatic aberration, contributing to sharp, color-accurate imaging, and each of its lens elements features Ultra Multi-Coating to improve light transmission and reduce ghosting and flare. An internal focus system prevents the front end from rotating which allows more effective use of variable filters.

A durable metal barrel with a wide focus ring and manual aperture control ring offer tactile control over focus and exposure. A n included, removable lens hood deters stray light from entering the lens, while protecting it from accidental impact and precipitation.

Forget about the memory foam!
Size: Twin 3 Inches
My sleep quality is fantastic on this thing, and I don’t even sweat like a memory foam cover! I was scared to spend the money but I’m glad I did! It’s really helped my back and overall pain, as it rises to fit the empty spaces left by flat firm mattresses.

Pretty Good
Size: Queen
The product arrived at my street address instead of my PO Box address last minute - without me getting prior notice that it was to large to be delivered to post office. Not sure why the seller did not notify me and let me know what was happening. The quality of the latex topper itself is good, covering nice with a zipper to take off and wash. There was no smell after about 5 minutes of coming out of the packaging. I am using it as extra padding for a new mattress which is pretty firm. After sleeping on it last night it helped just enough - perhaps someone who needs a little more cushioning should get the 3" topper version.

Soft and comfortable.
Size: King 3 Inches
The packaging was big and heavy and required 2 persons to move. The pad is soft and very comfortable. The latex had a bit of smell, but not too bad. Overall I am satisfied with the product.

Inaccurate
Size: Queen, Size: Queen
It was advertised as having an organic cotton cover, it came in a polyester cover. I thought because of the name “Talatex” that it was talalay latex, it is too firm to be talalay though. It’s a decent firm latex topper with a cover, but overall I feel it was deceptive inaccurate advertising.

Great mattress
I bought a Saatva that gave me horrid back pain because I’m plus-sized and a stomach sleeper. I started floor sleeping to rectify it, and I love this. I put it on a thick workout mat, and topped it with a folded mattress topper. I sleep well. Sometimes I sleep too well.
