Versatile, relatively compact, and compatible with full-frame K-mount DSLRs, the HD PENTAX-D FA 28-105mm f/3.5-5.6 ED DC WR Lens from Pentax will be a perfect pairing for many shooters thanks to its wide-angle to medium telephoto range. The lens also features an f/3.5-5.6 variable aperture to help keep size down while also utilizing ED glass elements to reduce aberrations. The lens sports both Super Protect and HD multi-layer coatings in order to protect against accidental damage and reduce flaring and ghosting.

Focusing is fast and quiet thanks to the integration of a Supersonic Direct-Drive Motor and the lens has a Quick-Shift feature for fast switching between auto and manual focusing. The lens also focuses as close as 1.64' and it has a 9-blade rounded aperture diaphragm for smooth out-of-focus elements. Additionally, it is dust- and water-resistant with eight seals to protect from intrusion.

Covering wide-angle to medium telephoto perspectives, this versatile 28-105mm zoom offers a convenient option for full-frame K-mount Pentax DSLRs and is also compatible with APS-C models, where it will provide a 43-161mm equivalent focal length range.
Variable f/3.5-5.6 maximum aperture ensures a compact size while offering a wide range of versatile focal lengths.
ED glass elements are featured in the lens design and help to control chromatic aberrations and reduce color fringing for increased clarity and color fidelity.
The High Definition (HD) multi-layer coating is utilized to reduce reflections, flare, and ghosting for improved contrast and color in more trying lighting conditions.
Super Protect coating will help keep the optics safe in the event of accidental impact or if it comes in contact with water or dust.
Supersonic Direct-Drive Motor (SDM) ensures fast, quiet, and smoother autofocus operation.
A rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing shallow depth of field techniques. It is completely rounded between f/3.5-6.3 when at 28mm and between f/5.6-10 when at 105mm.
A weather-resistant design features eight seals which better permit working in inclement conditions.
Includes PH-RBS62 lens hood to limit flare from light sources.
Optional S-80-120 Soft Lens Case is available to protect lens during transport or storage.

This Pillow Is A Must Buy!! What Are You Waiting For?
Size: Queen (Pack of 1)
This is, without a doubt, the best pillow I have ever owned. One of my favorite features is the adjustable shredded memory foam fill, which allows you to customize the loft and firmness by adding or removing foam to suit your sleeping preferences. As both a side and back sleeper, I found it incredibly comfortable and supportive. The overall quality is excellent, from the materials used in the pillow itself to the thoughtful packaging. The removable cover is washable, although I personally use a pillowcase to keep it protected. I also appreciated that extra foam is included, making it easy to fine-tune the pillow over time. The difference in my sleep quality was noticeable from the very first night. I’ve been sleeping more comfortably and waking up feeling more rested ever since I started using it. Considering the quality, comfort, and customization options, I believe the $75 price point is well worth it. I am so impressed with this pillow that I plan to purchase another one in the future.

This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability
Size: Queen (Pack of 1), Size: Queen (Pack of 1)
I purchased the DreamyBlue Signature Adjustable Pillow for my husband because he often experiences back discomfort, and many of the pillows we had previously would become flat and lose their support over time. This pillow has exceeded our expectations. It is incredibly soft, comfortable, and comes with extra filling, which allows you to adjust the firmness to your personal preference. We really appreciated having that option. Even after extended use, the pillow has maintained its shape much better than other pillows we've owned. It provides a plush, cozy feel while still offering good support. My husband finds it very comfortable, and it has quickly become his favorite pillow. This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability. I would definitely recommend it.

Finally Found a Pillow Worth Keeping
Size: Queen (Pack of 1)
I genuinely feel like I’ve tried every pillow on the market. At one point, I thought Amazon was going to flag my account because I bought and returned so many pillows trying to find the right one. This is the only pillow that made the cut. The shredded memory foam filling makes a huge difference because the pillow is both soft and supportive, while still being adjustable to fit the way you sleep. It arrives extremely full and plush, and it even comes with an extra bag of fill, which honestly surprised me. I ended up removing about half of the filling to get it exactly how I wanted it. I’m a side/stomach sleeper, which can make finding a good pillow difficult since most are either too thick or too flat. This one was perfect because I could shape it exactly how I sleep. It stays cool throughout the night, has a slightly heavier premium feel, and feels much higher quality than most pillows I’ve tried. Super comfortable, supportive, and customizable. I would absolutely recommend it and would definitely buy it again

A bit expensive
Size: Queen (Pack of 1)
Waited to give a review on this one because I needed several nights before I had any idea if it was as good as everyone says. I've had a real problem finding pillows lately. Either they're too soft to provide support and I wake up with a stiff neck or they're too sturdy and I wake up with a stiff neck. Contour pillows have worked best for me, but they fall under the category of too sturdy. I also toss and turn too much at night, which means I always end up in an awkward position with contour pillows. So I took a chance on an obscenely expensive pillow, and yes, that is the reason for one less star. I'd happily pay $70 for a pillow I thought was amazing and comfortable and perfect, but this one wasn't quite it. It IS comfortable. I have slept on it for a month now without it making my neck stiff, so it does actually provide a good balance between soft and sturdy. They make it easy to stuff the pillow to your preferred fluffiness and even provide extra stuffing if you need it, which adds to the degree of comfort. While the pillow does provide good neck support, I toss and turn a bit trying to find a comfortable position when I first try to sleep. The stuffing within the pillow moves around at night, most notably shifting to the side and the pillow is notably flatter now than when I first purchased it. You can fluff it out, similarly to a down pillow, but it doesn't seem to retain its shape on its own. In some ways, that's good because what it does instead is try to retain a shape that fits you. So yes, this is a really good pillow. One of the better ones you can buy. But it's really expensive for a pillow.
