I do a lot of very low light animal photography. I cleanup the pictures for noise, and had no preconceived notions of how well the converter would work.
The converter is sturdy, works wonderfully with the Pentax K3 Mark 3, and the 55-300PLM. The lens focuses just as fast and surely as before. There is no vignetting detectable. (I add some vignetting in post just to highlight the subject). The photos above are all low-light shots under very difficult conditions. The squirrel with belly presented was the only one in "reasonable" conditions. I frequently shoot at full 300mm and around f9.0 which is almost wide open at ISO 6400 - 25600. You do lose an f stop, as discussed in the documentation.
The mount is solid, sure, and has no play or sign of weakness.
This is a very good piece of gear to have at your disposal when you need that extra reach. I recommend it.
Shortly I will do some testing on the Pentax 70-200 f2.8 and 150-450 f4.5/5.6 lenses.
Highly recommended!

Contrary to what was published by another reviewer, this TC has the mechanical linkage for Pentax screw drive auto focus, as well as electrical contacts for Pentax and third party HSM/USM drive motor AF. The only caveat to this is that some older Pentax camera bodies do not have the PZ contacts that are used for USM/HSM AF motors. In these cases it will try to revert to screw drive. If the lens is not capable of screw drive, it will not AF with with this TC.
There is no appreciable loss of image quality when using this teleconverter. I also don't have color fringing issues with my favorite Pentax telephoto lenses.
I got this so that I could specifically use it with a Pentax 100mm f/2.8 WR D FA smc Macro Lens for Pentax Digital SLR Cameras . I am a huge fan of that macro lens, but I wanted better magnification. This 1.4x teleconverter works perfectly with it, giving much better magnification.
Note that when using the teleconverter and the macro lens together, the largest aperture I can get changes from f/2.8 to f/4.0.
Note, too, that more magnification means it becomes all the more necessary to use a tripod for tack sharp images.
I absolutely love this combination. I almost exclusively shoot flowers now with this pair, and I'm consistently happy with the results.
