Pros: Robust construction, optical quality, is tropicalized

Cons: Not compatible with full frame, price from new, tends to unbalance the camera

Opinion: Bought second-hand, after some generic tests for the fine adjustment of the autofocus, I immediately imposed the "baptism of fire" at the Monza racetrack, and I must say that I was very impressed. Used on the 60-250 mm f/4 and 300 mm f/4 and grafted on the K3-II, I did not detect substantial decreases in sharpness of both lenses, and a near total absence of chromatic aberrations, except on extreme contrasts. More complex is the talk of autofocus. Taking note of the note slowness of the first generation of the SDM, with the addition of the multiplier does not slow down much, but obviously struggles a little more to keep the subjects in focus fast moving, both for the obvious decrease in brightness of the lens (1 stop), and for the equally obvious decrease in the depth of field, so it takes a little more expertise. Stretching the optics to which it is paired, it tends to unbalance forward the whole set, especially with the 60-250 zoom, which at maximum focal becomes challenging enough to wield, and it is highly advisable at least the monopod. Attention, it is not compatible with the full frame format of the K1. If you use paired with 200 f/2.8 and 300 f/4 you must set the APS-C cropping mode, otherwise it vignettes heavily. Anyway it's a well-made accessory. Having bought it used I can not criticize the price, but from new it should cost about fifty euros less to align with the most qualified competition. Full rating 8

Pros: Construction, tropicalization

Cons: Price

Opinion: Purchased in 2014, the use of the shed on the 300 / f4. I really needed it, so I brought the focus to 420 mm. I would have preferred that Pentax did a 2x, but you can not have everything in life. The first time I put on my k20d with 300 / f4 I was shocked. All made shots were overexposed. I immediately thought of the rip-off, very high cost of 1.4x and a lack of results I expected. usually shot with iris mode, I started to do various experiments until I realized that its use was linked to under-exposure by one stop. It is now a year and a half that I use with great results. My photos in the blog can prove.

Pros: Construction of excellent workmanship and materials.

Cons: Price a bit 'high

Opinion: I purchased it for use with the 60-250mm. Before using it I did the firmware upgrade as suggested by Pentax and sharpness seems buona.rnL'ho also tried the 70mm f / 2.4 fixed that maintains excellent nitidezza.rnVolevo add that you can also adjust the duplicator the fine focus, which I did with both 70mm and with the 60-250mm and the adjustment is memorized for each objective that is coupled to this multiplier. So I think the Pentax has done a great job. Especially considering the fact that for autofocus is provided for both the operation with the engine optics or through the PTO of the reflex. The camera automatically recognizes and selects the AF faster depending on the perspective utilizzata.rnNota painful price that I think is higher by at least 50 euro to the concorrenza.rn

Pros: I have not found

Cons: yield very little, chromatic aberrations, slowing AF

Opinion: bought and sold in a few days. Coupled with Pentax DA * 300/4 the quality of the shots is obtained embarrassing, both TA that closing stop of 1-2; AF slows noticeably becoming very inaccurate in light conditions good / excellent. Introduces heavy chromatic aberrations. I would not complain of the price ... if only it had been used.

Pros: Materials, tropicalization

Cons: Price

Opinion: I bought this TC finally compatible with SDM (eccheccasso pentax, finally!) For use with DA300 and DA60-250 both f / 4. What I found was: rnNitidezza: excellent on 300, no loss. Good on 60-250, the optimal closed if a stop.rnSfocato: perfect 300, perfect on 60-250rnVelocità and AF performance: unchanged at 300, unchanged on 60-250. rnAberrazioni color: none out of 300, none of 60-250rnMicrocontrasto: slightly less than 300, slightly less on 60-250.rnHo bed of some exemplary optical performance with less, but I can only be happy with my price apart from that I find too high (should cost less than 70 € less!)
