Road map and 1.4x converter

I really think this would be a great one to get out as soon as possible. Lots of different users could benefit from it. It is something that other competitors have in good quality and AF. I feel I have everything I need for my wildlife photography in my price range except this. (K30 + Da*300 +Sigma 150-500). I don't think I would upgrade to a K3 or K5 variant unless this came out in the near future. This and faster more accurate AF would keep me happy for some time. Without it my eyes are always drifting to what I could do in this area with a Nikon variant.

Many, many users agree.

When they release it,I can see it being one of the fastest sellers during the first 12 months and Ricoh being unable to fulfil the market demand.

Which begs the question why don't big Companies ask potential customers what they want? If I were running a business I think I would try and find out what the customer wanted then you know you've got a market. I'm sure like other companies Ricoh must spend a fortune on Market Research but have they ever formally asked questions like that on this forum or the American one? Or are we deluding ourselves that real enthusiasts are a significant part of the market?

I guess they survey the home market, the fact they have one on the road map shows they must have done research to come up with the r & d for a teleconverter.

There are loads of 1.4x to 1.7x TC's available SH
Why would you want another apart from having a moan!

im curious, looking at your sig which lens would you use with a teleconverter? because i dont think an af tele will work to good with the 300mm and with the 50-135 will fall short of your 300.

Until pentax bring out a 300 2.8 or 400 2.8 a tele will be wasted I feel.

I would love an AF Teleconv with SDM capability to use with my DA*300. A 2x would be great but I will have to survive with a 1.4x.

I currently use a "manual" Pentax 2xS with mine and get some excellent results.

The point I was raising is would the af even work with a 1.4 teleconverter?

A 1.4 would also only make a 420mm f/5.6 lens this length and speed is virtually already covered by Sigma and has HSM and would probably have better IQ too.

----------------------------------------
What current Pentax AF 1.4x converter can I use matched to my DA* 300mm with minimal loss of IQ and AF speed then please, as per Canon, Nikon?

Most currently available TC's pass ALL the electrical contacts straight
through. Pentax can't improve on that with a new one.

Optically the Tamrons/Teleplus TC's are quite good. Unlikely that
Pentax can do much better than that with a new one.
It is after all just a magnifier

They may be able to tweak the AF in the camera to work better
with a TC including tweaking the SDM...... but you haven't
asked for that. Something to moan about later if they ever
release a TC.

The Pentax 1.7x adapter works well with the DA*300mm and there's
was one for sale here last week for a very low price.

I prefer to use the 55-300mm or Sigma 150-500mm with the
Jessop 1.7x TC.

A Pentax AF 1.4 converter would be an excellent addition to the Pentax line up. In terms of IQ I still believe that the A series 1.4 is better than any other 1.4 or 1.5 converter, an updated af (with sdm capability too) Pentax model with even better coatings would be welcomed by me and I suspect many others

And WR!!!

Hi
I didn't say I wanted one , and I am not moaning

Nor was I ! Not sure what I said to provoke the vitreol Algi
Any way I have the Kenko 1.5x and it is pitifully slow although optically reasonable on the DA* 300. I have tried the 1.7x Pentax and it was temperamental and slower still. I have used the Kenko with both the 55-300 and the 150-500 and the IQ was inferior to just cropping, in bird photography at least.So why have I read loads of threads about these being the only ones with AF if Pentax have these other ones already and why would they put another one on the road map?
I presume from your comments that you are saying the AF is slow with the camera and the lens and will be even worse with the TC. What I am saying is that isn't the case with a Canon or Nikon equivalent set up and I was hoping Pentax could find away of matching it? There's a difference between hoping and moaning.
