As we all know, Pentax still have a considerable number of lenses to deliver on their existing roadmap and it's fairly obvious, from many posts, that quite a few people have requirements for TC's and a long tele-zoom that don't figure on any known plans that Pentax have for the "
very near" future.
It's also quite clear that while Pentax have the ability to develop their own lenses, especially primes, they are pretty stretched on development resources and have partnered with Tokina to co-develop the zooms. Although they have their new lens facility now in place, once again, it's fairly obvious that it's going to be fully committed to the production of all the new DA* and DA lenses already on the roadmap, without adding, perhaps more specialised, products.
In fact, when I asked Pentax about having a dedicated TC, the response suggested that they could do this only if they dropped a lens from the roadmap! It did come from a reasonably solid source.
In the light of this, what do you feel about the idea of Pentax farming out some of their lens requirements to Tokina/Kenko and maybe Tamron if feasable?
I'm specifically thinking that a "Pentaxised" Tamron 18-250 could be a very good way to attract the ex P&S customers looking to upgrade, in fact I may even be tempted by an all in one travel zoom, even if it just had the latest SMC coating and nothing else, Dual mechanical/SDM AF could be an expense that would make it unnattractive price wise.
Another area I could see as a useful co-operation is to have a couple of TC's specifically made for Pentax by Kenko-Tokina, especially a 1.4x and 2x from their Pro range, which they currently don't have in Pentax mount.
Pentax could have a small chip inserted into the TC's to give the data to the camera for correct SR and lens Exif data. For non-chipped TC's they could do a simple firmware patch to have a manual entry for TC usage and two settings say 1.4/1.5x and 2x. - Job done!
Finally, why not a Pentax re-badged (plus SMC) version of the Tamron 200-500 Di zoom? This lens only comes with in-lens AF motors, so up till now it was never available in K mount. but with with the advent of the K10D and now the K100D Super, it would be a great way to have a very reasonably priced (less than Bigma) long tele-zoom for Pentax with SDM and with Pentax SR it would be rather nice, I would certainly be in the market for one, a great addition to the 60-250 for the birding/sport/aircraft guys (me!).
I'm sure that Pentax could give enough volume business to Tamron to make this a worthwhile project, what do you feel?
If you're with me on this I'll keep on throwing the mud at Pentax, maybe some will stick!
FURTHER THOUGHTS
Just to keep you all on your toes!
Here's my current list for them for the near future and next year (after the current roadmap is complete)!
Not in any real order, also I've left bodies out, they can sort that out for themselves!
Lenses
Pentax primes, they seem able to do these okay on their own!
DA 16mm f2.8 (f4.0 min) smallish (pseudo pancake) rectilinear W/A.
DA 24 f2.0 and/or 28 f2.0
DA*85 f1.4
DA*135 f2.0
DA*400 f5.6
(Bigger (faster) longer primes later, or re-engineered FA*300/2.8 and 600/5.6 into new DA* style housings, they'll still be v. expensive I guess!)
Zooms
As above - By OEM from Tamron (can't be QS or WS, that would be too much re-design), just add Pentax style focus/zoom grips and have SMC coatings.
DA 18-250 (SMC) super zoom
DA 200-500 (SMC, SDM), maybe this could be a Pentax badged exclusive? This lens has a much higher user rating on Photozone (3.8) than the Bigma (2.63), or any other long idependent tele-zoom. It's also a reasonable price, it's less than a Bigma.
By OEM or joint agreement for an SDM version from Tokina
DA 80-400 SMC (SDM?) based upon the Tokina AT-X 840 AF D (Pentax exclusive).
It's predecessors were a very popular choice as a compact superzoom, but real hard to find. I had one and sold it to fund my FA*300/4.5, I almost regret selling it now, it was a very useful lens.
Here are some examples I took with my istD
Tokina AT-X 80-400mm AFII Photo Gallery by Richard Day at pbase.com.
I know this would be a popular choice for those not wanting something as long or large as the 200-500 or Bigma.
By OEM from Kenko-Tokina
1.4x (Pro) TC with chip
2x (Pro) TC with chip
Again like the long telezooms above, these could also be exclusive, as Kenko-Tokina don't have Pentax mount available for these two, just the Pro 300 (3x)
Plus a firmware patch for setting SR for use with non chipped TC's
Accessories
Advanced flash system using a wireless (+ radio?) commander
Slave receivers compatible with studio lights
Suitable wireless (+ radio channel) flash heads (GN 36) for hot shoe or lens mounting system for multiple flsah head macro use (instead of ring flash)
I think these items would make the "system" very attractive to everyone, both newcomers and fanboys!
I'm sure there are other more specialised items that are desireable, but I think that they are/will be best served by independent makers.
Any other (sensible) ideas anyone?
