Any info about these two mid-range OM System zooms that are in the roadmap?

Thanks Finnan. I did use the Rösch collar for the 100-300mm in the past, didn't know they also had one for the 50-200mm. But then, it doesn't appear on their website, does that mean they didn't go ahead making it?

They are notoriosly slow in updating their web site, it literally takes years...

But yes, I emailed them about two years ago, and payed-up what they asked for. Many weeks later I received a small parcel containing the Rösch tripod foot for the PL 50-200.

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

If it shares the same 72mm filters the 70-250mm F3.5 would complement the 12-100mm F4 very well. Not too much overlap in focal length, same zoom direction, same function button, full Sync IS.

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.

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?

Those old 4/3 lenses are basically unobtainable. I tried to find a 150/2 occationally for years. If available at all it is extremely expensive

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.

One of them will just be a re-issued version of the 40-150/2.8 PRO, with better coatings, better weather-sealing, and possibly OIS. The other would be a 70-250/3.5 PRO with SyncIS, that also accepts tele-converters (OMDS has patented this lens).

In addition, we are hoping to see new f/1.4 primes at 10, 14, 28, or 40mm, to match the recently-issued 20/1.4, as Sigma has patented all of these lenses.

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