I would like one... but maybe not the price. At the end if the article is "Both sources confirmed there will be a 1.2x teleconverter too!". I hope this is a typo and that it is not a bespoke 1.2x but the rumoured 2.0x.

If that turns true, the lens better be F/4 and not F/5.6.

The smart money is on f4.5! That's not as stupid as it sounds. The difference between f4 and f4.5 in terms of diameter of the front element is significant. 400mm f/4.5 would be a shade under 90mm, whilst f4 would likely be the wrong side of 100mm. Either way, you're looking at a very large optic.

I'm hoping it will be f5.6 as per the original rumours. Anything faster will be very heavy and expensive. Just look at the Canikon equivalents.

I see a lot of Panasonic 100-400mm lenses around and if Olympus could do this at Pro quality for under £2000 they should sell loads.

Yes, the original rumour (from Simon) was for a variable aperture at F4-5.6 & that lens wasn't going to come till the end of 2019.

I thought the original rumour I saw was even slower than 5.6. Maybe confused though.
Canít see a 2x converter being much help even if it is 4.5 and not 5.6, losing 2 stops will limit usefulness.

Hi,
What I meant was that, if that there is a MC20 in the plan, and assuming it is designed for compatibility with the 150-400 then the lens should be F/4. It the MC20 is a false rumour then the lens could very well be F/5.6 and then compete with the Panasonic. It would also cannibalize with the 300 F/4 and fill the gap above the 40-150 F/2.8. I agree that 100mm front lens is quite large, still not excessive. Look at e.g. the Canon 400 F/4 DO, weight 2.1 kg. Zoom components and glass would probably push that figure a bit. Filter could be drop-in. It would be expensive, though.

Is it possible to make a DO (or PF) zoom lens?

The lens information I refer to is here & the MC20 here with another reference to the MC20 here.

imho Olympus need a super telephoto lens in there line up for M4/3 for sport and wild life a 300 f2.8 or 400 f4 yes it would cost a fair bit but not as much as Canon / Nikon's super tele's .

I'd get a 150 - 400 F4 - F5.6, but might have to wait for Black Friday 2019 reduction and maybe + a 15% off code & cashback promotion.

At 300mm would it be about F4.6, just over 1/3 stop slower than the 300mm F4?

If it is a 1.2 x teleconvertor, which would make it 180 - 480mm, at 420mm (same as 300mm + 1.4x), would it be about F6.3, once again only 1/3 stop slower than the 300mm F4 + 1.4x at F5.6.

Does that sound about right?

Re: Olympus 150-400 Rumour
 
The 1st December rumour on that web site mentions '2 telezooms' amongst other items to be announced.
Perhaps there is a fast zoom for professional sports photographers, and something slower & less expensive for enthusiasts?

I think a x1.2 teleconvertor makes sense for a fast long zoom - as it would be only ~1/2 stop slower.
Designing a top-notch teleconvertor for a zoom lens whilst avoiding bokeh problems across the zoom range must be very challenging - as shown from the occasional behaviour of the MC-14 with the 40~150 Pro zoom (which isn't seen when the MC-14 is used with the 300 f4 prime).

Re: Olympus 150-400 Rumour
 
The 1.2x converter is almost certainly a typo for the 2x converter. There has never been one before and why would you bother for just a 20% increase? That rumour site does have useful info at times but it has many errors and mistakes.

I don't know about the 1.2 x TC but there is an Olympus patent for a 1.7 & 2.0 x TCs. http://thenewcamera.com/olympus-2-0x...erter-patents/
