This is not a full frame converter

Everything I read on this converter before I bought it said it would work on the K-1 and it does function and operates the lens, but it is not a full frame format, your pictures will have a dark ring around the outer edges. I do not recomend this for the K-1, even though I have found no other options

Great when paired with 300mm telelphoto

I bought this to go with the 300mm telephoto, don't see that many other uses for it.

Solid all metal construction

Solid all metal construction. Works as described. I like it because I have an old Tamron 70 - 300mm 'Macro' lens that becomes a 450mm lens on my K3. When I add the converter it becomes a 630mm lens. This makes it fun for wildlife shots. The other thing I like is that the minimum focusing distance does not change and this makes it great for macro. I do not see any difference with my photo quality when I use this converter.

Part of DA* 300/4 design

I have been using this for over an year now paired with the DA* 300/4. There is zero drop in image quality and autofocus speed, as if the two have been designed from the very beginning as parts of a 420/5.6 lens. It performs very well with DFA 100/2.8 macro and even DA 50-135/2.8, but it really shines with the DA* 300/4. Based on a quick viewfinder check with a venerable MX film camera - I expect it to be compatible with the future FF camera.

Must have when shooting wildlife with a Pentax DSLR. When use with the DA* 300mm f4 it provides an effective 420mm at f5.6. The actual 420mm focal length of the combination converter and DA*300mm f4 provides an effective crop factor equal to 630mm on APS-C Pentax cameras while providing very accurate autofocus. Works with either SDM lens and in body screw drive focusing lens.

It's the perfect companion for outdoor photographers who encounter rain, mist, or splashing water, providing a durable solution for capturing stunning images in less than ideal environments.

The converter is treated with PENTAX's exclusive HD coating, which enhances light transmittance and reduces reflectance compared to traditional multi-layer coatings. This advanced technology delivers exceptionally sharp and clear images, effectively minimizing flare and ghosting, even when shooting in backlit situations.

Despite its powerful magnification capabilities, the HD PENTAX-DA AF 1.4x Rear Converter AW boasts an extremely small form factor, measuring a mere 20 millimeters in length. This versatile and portable design does not compromise on image quality, allowing photographers to capture larger, more detailed subjects even in close-up shots, while retaining the lens's minimum focusing distance.

The converter is compatible with both camera-driven and lens-driven AF systems, including SDM- and DC-series lenses, making it a convenient choice for those invested in the Pentax ecosystem.

Please note that when using the HD PENTAX-DA AF 1.4x Rear Converter AW, the maximum aperture of your lens will decrease by one stop. For optimal performance, ensure that your camera's firmware is updated to the latest version. Compatible camera bodies include the K-3, K-50, K-500, K-30, K-5 II, K-5 II s, K-5, K-01, K-7, and K-r. Autofocus functionality is supported with PENTAX lenses that have a maximum aperture of f/4 or brighter.

In summary, the HD PENTAX-DA AF 1.4x Rear Converter AW is a durable, versatile, and innovative solution for photographers looking to extend the reach of their K-Mount lenses without sacrificing image quality or convenience.
