This roadmap is not new, it has been the same for some time now. A new one may be released at PMA in early March.

I just hope that the DA*60-250/4 has a tripod collar. If not, I just won't purchase one. I could really use that lens, but not if I can't rest in upon my monopod. For sure, the DFA 300mm has to have a tripod mount?

I am most intrigued by the DA 70-300; I wonder what the aperature range on that will be...would be great to have a constant F4 or even f2.8 and priced under $1,000.00 US.

My bet is that the 17-70 and 70-300 will both be f/4-5.6 but will be equiped with the lens-based motor. I think only the DA*'s will be faster constant apertures.

To purchase the Sigma 17-70 and 70-300 now, or to wait for Pentax.....hmmmmmm.

I think Pentax updated the roadmap, actually. Although all the lenses are the same, they changed the order around and added projected release dates.

I would go for the 50-135, but considering that it's not unique to Pentax (Tokina is using the same optical design for Canon and Nikon mounts) and since I already have the FA* 80-200mm, I'll be letting it go...

I saw 645 D FA 50mm f2.8 going to be released at the same time as 645D body. Quite excited about this!

I am not sure how the conversion will be using this lens on 645D...

645 D FA50mm equivalent to 32mm on 135mm camera; with conversion factor of 1.3X will result in 40mm on 135mm camera focal length...?

Looks like the same road map to me, my geusstimate is that we'll see a new one in three or four weeks during PMA, i wouldn't be surprised if the new one is a little more crowded then the current ones

The pictures released, and also the prototypes shown at Photokina, didn't have a tripod collar. It may be that there will be one, as the Tokina version of the 50-135 has one, but I hope it's removable. I actually hate the design of the non-removable Tokina type, I had one on my Tokina 80-400 and it always got in the way.

My FA*300/4.5 doesn't have a tripod collar and I never miss it. It's quite a light, small lens, it's just the hood that makes it look huge.

BTW, the DA*60-250 is about the same size, I compared them at Photokina (through the glass case!).

If the lenses are big, like the Sigma 70-200, 100-300, 135-400, 170-500 and 50-500, then a removable tripod bush is desirable. The Sigma design is excellent, it's just a pity about the IQ!

My sources have indicated that the DA 17-70 will be f4.0 constant and have in lens SDM (sonic drive motor) and will cost more than the Sigma but will be of a higher standard optically (they would say this naturally!). I have no info on the 70-300, but it is rumoured to be f4.0-5.6.

But as they are still some way off (year end), the exact details, pricing and also availability are liable to change. I suspect much more will be known at PMA.

I downloaded the RM when it first appeared, there is no change.

As far as the designs not being unique, this is partially true. AFAIK the differences will be in barrel design, internal mechanical design, fit and finish to internal surfaces to minimise reflections and possibly different coating treatment on the internal elements. The common features are the optical design and the element mouldings in their raw unfinished state, everything else is processed independently.

A wealth of knowledge as always Richard. Any inside info on the DA 35, is it a new lens (f1.4) or just a rehashed FA 35 f2,

I'm almost as much in the dark as everyone else, including my contacts. AFAIK, it will be a f2.0 design, I don't know how much of the design will be borrowed from the existing FA 35/f2.0, or if it will completely new (which I personally doubt), just that it will be a QS design, no mention of SDM either.

I think that pushing the aperture to f1.4 would increase the price substantially with no real optical improvement, in fact it could worsen. Many very fast lenses are not that wonderful, just compare the FA 50 f1.4 against the f1.7, many state the f1.7 is actually a better lens at the same apertures. The same held true of the Zuiko f1.4 compared the f1.8, and I believe with other makes as well.

I believe the 55mm may well be a f1.4, but again nothing is concrete.

Hopefully PMA will have some updates, but don't count on it.
