Re: Olympus 150-400 Rumour

If it is a 2x teleconverter, 300 - 800mm F8 - 11 isn't something I'd be interested in , so I hope it would be an optional extra, rather than bundled with the zoom and jacking up the price.

Re: Olympus 150-400 Rumour

I really don't think a m43 long lens at anything slower than f5.6 makes any sense at all. In any case, 100-400 should be enough. If you really want longer, then a prime is probably the best option rather than a TC.

Re: Olympus 150-400 Rumour

I would think an MC20 could only be used on an F2.8 lens or faster, so I don't know what other options besides the MC14 will be coming or not. A 1.2 X TC maybe a typo whereas there are patents for 1.7 & 2.0, but I doubt anything more than 1.4 with an F5.6 long end of the lens (at 400mm) would be worth using, but still attractive at 560mm F7.8 in good light (with Sync IS). But..... it's still rumours & speculations at this point.

You are probably correct...

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.
... however, bear in mind that this extra (miserly) 20% would take you from 800mm fl to 960mm fl (in 35mm terms).
Though I think you'd have to forego the coffee if using such a lens combo - even with Olympus Sync-IS

Re: Olympus 150-400 Rumour

Looks like its being officially registered and it is an f4.0 ! so it's going to be big.

Re: Olympus 150-400 Rumour

That's just what the Rumours guy is saying. Last week he didn't know whether it was f4 or f4.5 There's nothing in the info he links to other than it refers to a lens.

Re: Olympus 150-400 Rumour

The only more realistic information I know is from Simon & he was saying it was going to be F4-5.6. That would be a more realistic size, but we won’t know until we get more concrete details. Also, it may be for one of the other lenses coming.
