K3ⅡにDA☆300/F4とHD55-300ED PLMを付けて1ヶ月試してみました。画質やAFも満足しています。薄くて軽いのでボデーとレンズの間にリアコンが付いている感じがなく一体感があります。お薦めです。

By far the best price available for a new teleconverter was on Amazon. I was a little concerned about the description with the mixture of Spanish in it and the mentioning of two lenses, but after receiving the lens, it is genuine Pentax. By the way it does not come with the DA 12-24mm or 16-50mm lenses (should be obvious but want to make sure it is clear).

Add to my 100mm for extremely closeups perfect match. NOT a cheap pair but one that improved my photography skills, or just made my pictures much better!

Pentax è un po’ una nicchia nel mondo delle macchine fotografiche digitali ma la qualità delle sue lenti non si può discutere. Ottimo moltiplicatore per fare scatti gli scatti più lontani, certi si perde luminosità quindi va gestito ma fa ottimamente il suo lavoro. Premium la custodia per portarlo in giro, sono soddisfatto

I was really curious (and a little doubtful) that the teleconverter would work with my Pentax 55-300 PLM and not slow down focus and not add distortion or undue optical degradation.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!

This high quality telephoto lens teleconverter from Pentax work like a dream with my 55-300mm Zoom Lens from Pentax. I bought it to give my moon photos the extra reach without compromising the quality of the photos. I have used various telescopes and third party lenses befor but was not happy with the results, short of spending a small fortune for a super telexend. Now, I can’t wait for the Super Blood Wolf Moon Eclipse on January 20/21, 2019 and see the results.

There's a lot of anti-talk about this teleconverter, and most of it is on the forums and is just flat out WRONG. Photographers are a weird bunch, so you can't always trust 'em. All I can tell you is that I rolled the dice and on my Pentax K3-II, this thing works PERFECTLY with my ALL of my Pentax glass, my Sigma 17-70, 17-300, 120-400mm and my Tamron 70-200. Caveat: my Sigma 17-50 f/2.8 won't play nice with it, but it's not the kind of lens you'd use with a teleconverter anyway, so it's no loss. The rest of the Sigma and Tamron glass both lock-on the AF so fast with this it's like it was made for them. Really amazing. It's still available on on Amazon for a COUPLE of HUNDRED dollars less than everywhere else, so it's a STEAL as well. If you're thinking about it, just buy it; you won't be disappointed.

This is in my opinion is a must have accessory for any Pentax user who needs that extra reach with their glass, whether it be for sports, wildlife or macro. Build quality is excellent and incorporates both SDM (silent focus) and old fashioned screw drive and as an added bonus its weather sealed as well (With appropriate lens and body) and it works well as I've used it in the pouring rain without any problems whatsoever, I was the one that suffered but that's a different story The only downside is a loss of one stop of light and focusing issues with lenses slower than F4.All in all worth every penny.Matt.

I was really looking forward to using this with my 55-300mm as an alternative to the heavy Sigma I've been using for birds. The zoom lens does not have the option of manual focus. It's auto only. With the converter attached it, it hunts a lot, and it seems to make the lens noisy. The birds are frightened away before I can get a decent shot. I have not tried it with any other lens yet, though I intend to try it with the 50-135 as a butterfly lens. I expect that it would be worth the money if the subject was larger than a distant bird or the lens was used with manual focus. I'm sorry I bought it but will try to make the best of it.UPDATE: I changed my score to 4 stars. I attached it to my Tamron 90mm and the teleconvertor allowed autoexposure and autofocus! It was extremely nice to get that little bit of extra distance and still get a good macro shot. The butterflies and bugs didn't seem to mind the noisy hunting it did. I wouldn't have paid the money just for that, but since I have it, I'll use it and be happy.

This long awaited tele converter from Pentax is probably one of the best on the market. The loss of sharpness normally associated with the use of a TC is just not there. It is so sharp, that when I use it with my SMC Pentax-DA* 300mm f4 lens I have to look at the EXIF data in order to discern whether or not I used the TC. It is extremely well made, and designed so that the effective focal length of the lens+TC combination is reported to the camera. This allows the shake reduction to perform perfectly. It is not an inexpensive piece of glass, but in my opinion it is well worth the price to have a TC that retains the sharpness of the lens with which it is used. This TC also works well with my Sigma APO DG 150-500mm F5-6.3 OS HSM lens, although Sigma has not made the updates to their lenses to report the correct focal length for the shake reduction. I normally use the the Sigma OS when using this lens and have not noticed any difference with or without the TC.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.
