Yes OK its hard to see what size a object is when you can only see it against other objects the size of which you also do not know, but even if its not the same lens its DNA looks similar, on the larger lens the zoom lock switch is a clear clue as to its origins, the smaller is a rebadged Tokina 70-200 f4 for sure, and the reason for the larger lens is Full Frame the 60-250 is only APSC, and the future is full frame, Sony has just stated it intends to have 20 full frame lens on the market in a few years, maybe the have come to the conclusion if you want to be number one you have to do what the guy at number one is doing Nikon!!

What about Canon?

I think it's very likely a fullframe lens, but what makes you so certain it's an f/4 lens? Just look at the diameter in relation to the lens mount. This is a fat lens! Fatter than the 50-135/2.8, which in turn has about the same diameter as a Canon or Nikon 70-200/4 (as you would expect).

Also, it has a tripod collar, which suggests it's heavier than the 50-135.

I want a very fast portrait lens with WR, not another walk around.

Even if the lens don't have IS I would love a SR switch on the lens or in the body to make switching easier.

Just out of curiosity, since the DA 17-70/f4 is still in production, would this new lens compete with the older 17-70/f4 lens price wise and IQ wise?

How do you know it is in production? They are probably still selling old stock. The FA Limiteds haven't been produced in several years but are still available. Same with the FA 35/2. The FA 20-35 was listed on the Japanese site until just recently.

Don't know about whether in production or not, but certainly not discontinued....it appears on Japanese site as well as Canadian Ricoh site.

I'm assuming you're talking about WheatLow.
Or maybe that Ken Stone-bad guy, but he's just misinformed rather than targeting Pentax.

there's the DA* 55 f1.4. It's WR too There's also the DA*50-135 f2.8 if you don't mind it being a zoom, and it's not a walkaround lens. It's not "very fast", but I've yet to see a telephoto zoom offering brighter than f2.8.

Olympus had their 35-100 F/2, which is a 50-135 equivalent on 4/3. But it was twice as expensive as the 50-135. And it is for an orphaned system now...

but on 4/3 you need less glass so it is the size/ weight of an f4 on our mount. also it would have the DOF of f4 due to sensor size.

So? F/2 is F/2 for exposure purposes.

BTW. The 35-100 for Olympus weighed 3.64 lbs. It used a 77mm filter and was 3.8 x 8.41". Compare that to the 50-135. It was bigger than even the 60-250.

thanks for pointing that out. I stand corrected! also, could it still be in production? seeing that 4/3 format (E30, E3, E5) is dead now....

I don't know if it is still produced, but you can still buy it for $2500.

supposedly the E-M1 can use 4/3 lenses, not sure if it works well or not. There were several beauties like a 300/f2.8 that were ridiculously good (but expensive) glass that was waiting for a modern body.
