Uh, no, the 70-250 f/3.5 will NOT take a 72mm filter. The absolute minimum clear aperture for the front element will be 72mm just for f/3.5 axial illumination at 250mm. To get good illumination off-axis, the front element clear aperture MUST be larger than 72mm. I suspect that even an 82mm filter size might be too small. Yes, that translates into a pricey optic.

HAND.

Thanks again, I'll make an effort to brush up my German and contact them. Or should I get the lens first...? 🙂

82mm filter would already be bigger than 300mm F4, and you think it's going to be even bigger than that? How big? Same size as the old 90-250mm F2.8?

There are several copies of the 150/2 on eBay starting at $1270. There are also two copies of the 300/2.8 for sale starting at $2100. These lenses are available, if you want them.

It would probably use the same 77mm filter as the 300mm f4. This would be a lens that would fill the zoom gap up to the 300mm f4 for me as well as give an f5 - 98-350 with the MC14 or an f7.1 - 140-500 with the MC20. Unfortunately it would probably be very expensive.
-
If a 70-250 f3.5 lens actually gets made, and if it takes at least the 1.4x TC, if it has Sync IS, and if it isn't too frighteningly large, heavy or expensive (yeah, right), then I'd be very tempted to flog off some other stuff and buy one.
However, I expect one or all of the above factors will scare me off, in which case a 40-150 f2.8 v2 with Sync IS might be very attractive.

You seem to speak with some certainty. Do you have any reference to the lenses you mentioned or are you just speculating?
