Pentax F 1.7x AF teleconverter -LIVES AGAIN!


does it work well with macro lens too?
Da100mm?
 

I got mine recently which is new but old stock and MIJ. Paid slightly about USD300 for it.:)

Hey Ben, this is Tri from VN. How does it work? I am interested in getting one :)

Thanks mate. Will go ask for it at BIC when I'm in Tokyo. :)

I would not recommend a $350+ teleconverter just for the sake of this purpose :)
You can use it if you have it though....
 


IMO, no point spending $350 just for such a purpose. This is not the cheapest and easiest teleconverter to get for Pentax. For macro, esp extreme macros, a Raynox, extension tubes or a cheapo reversed lens will get you the magnification at lower cost. Much larger magnifications as well. If its with the intention of using it as a teleconverter and the use with a macro lens is in addition to it, then its yeah; why not.

ah... i see... i was thinking more along the perspective that its a multi-purpose tool... can use as high quality TC, and to increase magnification for macro if necessary.

agree with you that the availability is a problem though :(
 

The sole reason, if ever I buy this TC is essentially to give me more reach with my lenses; whether my 100mm f2.8; or the kit lens.

Will there be any issue, if I use it with the Sigma 10-20mm? More vignetting? Or ... Anyone with experience with the photo?

Leong..I have this teleconverter..IMHO,maybe not worth to extend your 100mmf2.8 with this. You will get lessthen 200mm and aperture will be affected by the same factor. Getting a 50-200mm might be better andcheaper. If we do meet at the next outing....u can try my before u decide.
 

This TC has the extra fun factor.
MF near your target... the TC AF pretty fast spot on.
I am happy with the TC on my Pentax-M 200mm f4.

I am not critical about IQ... after all it is a TC... just enjoying it while I own it.
 

price is reasonable but still quite high :sweat:

u buy lor... i borrow from you to play during outing ;)

nah, I also wait for someone to buy, and borrow from him/her during outing :bsmilie:

expensive toy lah... not really necessary imo... TC with the contact for powezoom / SDM will do.

i wonder if pentax will invest R&D in a WR TC... that's really a missing link in their current line-up. :think:

imagine: K5 + 1.7x WR TC + DA*300 :lovegrin: full WR assurance while birding...
 

does anybody tried to ask EMJAY to bring this 1.7xTC here in singapore?
 

would give the 50-135mm more reach even at the expense of a stop of light or so.

i wonder if the production and qc so complicated that production is that slow or is intentionally slow?

Few months ago I asked about this TC but the sales don't seems to know this product.
But they can bring it in if you are able to provide them the part no & if it's available in Pentax Japan. :)

frankly, if there are a lot of interested parties, maybe someone can do a bit of organising and let one of the trusted shops know of this and do a mass order through them... with a guaranteed number, it will be more worthwhile for them to bring in and hopefully, charge a reasonable price for those who ordered.

its a business decision ultimately. if only 1 or 2 pple say they want, emjay may not entertain and the shops would never bring it in in case they get stuck with goods that no one wants.

any shop that can secure an order for 20 - 30 teleconverters will definitely make a bit of money... in the end, shop happy, pentaxians happy, emjay also happy.

worth considering? :think:

Not sure how many pentaxian wants this pricy TC?
But CN brand TC also not cheap either. :sweatsm:

Emjay can still bring in this TC loose unit together with dslrs/lenses shipment.
Maybe they may need the customer to pay a deposit 1st. :)
