SMC PENTAX 1.7x Teleconverter Lens (NEW)

PentaxForums.com Marketplace Listing

Item for Sale
SMC PENTAX 1.7x Teleconverter Lens (NEW)

Asking Price
235.00 USD

Item Location
N. California (United States)

Item Description
I bought this auto-focusing 1.7x teleconverter for a specific lens, but then sold the lens before ever using the teleconverter. It is brand new in the original retail packaging that includes box, caps, and soft case. Although it is pretty cool to acquire auto-focusing for a lens you’ve always had to manual focus, I bought it only for the magnification. Because I prefer to manually focus my lenses, and have no other lenses I care to "teleconvert" is why I’m selling it.

The specifications (I listed them below) state it is only compatible with f2.8 or faster lenses, and also excludes macro lenses. But when I tested it, the teleconverter successfully worked with all my lenses, including my f3.5, f4, and macro lenses (plus reviewers here at PF make the same claim). The YouTube video I posted below demonstrates it working with an M42 lens.

Specs:

• 6 elements in 4 groups
• Diameter x Length: 64 x 26 mm
• Weight: 135 g
• Mount: Front: Pentax KA, rear: Pentax KAF
• Magnification: 1.7x
• Light loss: 1.5 stops
• Super Multi Coating

• Provides autofocus capability with manual focus lenses
• Supports Tv or P exposure mode (in addition to M and Av)—does not transmit focal length and MTF information from lens to camera.
• Supports K and M-series lenses with a maximum aperture of F2.8 or faster (except soft 85mm F2.2), A-series lenses with a maximum aperture of F2.8 or faster in the focal range 16 to 400mm, except macro lenses, and SMC Pentax-A 35-105mm F3.5 (macro setting not usable). Will work with autofocus lenses but the adapter will take over focusing duties.

Free shipping for CONUS. I ship fast, same day or next via USPS Priority Mail.

Thanks for looking.

You do realize you can still manual focus with the adaptor, right? Just set MF, rather than AF-S, or AF-C.

Yes I know. Thank you for making sure, but as I mentioned in the ad I bought it specifically for one lens, and not for AF (I wanted to use my 180mm lens as a 300mm lens). However, I sold my 180 last night, and since I don't want the teleconverter for any other of my lenses, and since I prefer to focus manually, the teleconverter is no use to me.

Good luck with the sale. It's a handy accessory to have in a kit, for those that might be interested.
