I am not really sure but I would guess at least 2 stops.

The attached shots demonstrate an experiment which I carried out when I discovered the issue with the menu setting. I took these shots indoors in poor incandescent light to see if changing the setting made any difference. The first shot was the best that I got with 'Sequ + IS Off' set to the default 'On' position. The second shot was typical of those obtained with the setting set to 'Off'.

The settings for both were 1/20 sec, f/6.1, 200mm.

Thanks for the samples. Looks like it is reasonable to expect IBIS to give 2 to a probable max of 3 stops stabilization for the 300mm.

By default this is set to 'On' and this means that IBIS is switched off even if you take a single frame.

I couldn't make out why I was getting so many blurred images with my E-M1 until I discovered that the setting was set to 'On', which was cancelling out IBIS. Since turning it off my keeper rate has improved considerably.

Hello Ron

thanks a million for this tip, sorry i just saw this, and i think this maybe the problem, i just set it on Off, can't wait for the morning to see how thing will work for me, thanks so much again.

Great results there. Any attempts at low light, that is to say, handheld at 600mm FOV at about 1/100s?

Hello Hor and Ron

this shot was taken at 1/160 sec, ISO 400, f 6.7, ev +0.3, with the setting Ron me told me about. the bird was under the shade, and thus the slow shutter speed.

The second shot is the same but after apply Auto sharpen by PS element 7.

So it looks like the 300mm F4 will have OIS according to Olympus registration of lens in Russia. And it looks like lens was developed in collaboration with Sigma.

"Olympus considers to make the new 300mm f/4 PRO lens with OIS, to complement IBIS in Olympus bodies (which is less effective at really long focal lengths) ..."
Hmmm.... can't really agree with that. I have found the IS to be very effective indeed. I use a Canon 400/5.6 without IS on my E-M1 a LOT! It is a great combination, naturally only MF and wide open.... until yesterday.
Just got a Metabones Smart Adapter and now have the same setup with AF (S-AF only, but they are working on getting C-AF to work also) and full diaphragm control. Naturally I was eager to try it out, even though it was dark and dull out, typical Vienna Woods October weather. Here a few, all hand held with IS-1 on. ISO 800 and 1/50-1/60 second.

This one was through a not so clean double glass window.

How many stops that is I do not know, but I do know that the E-M1 IBIS has made many a picture possible with that lens that would have otherwise gone straight into the trash.

Good for you.

The rumor site has one more reason why IS is added to the 300: this would not be an attractive lens for Pana camera owners without the IS, and without that group of potential customers, the cost of developing the lens would never be met. Oly is a company, they have to include profit in their calculations.

I think that is the real reason and they have said that from the beginning. The bit about IBIS being not so good with long lenses was new to me, and I do not agree with that. Tried it today with the Metabones/Canon 400 + 1.4x Extender III with IS set to 500mm, (and it works like a charm. Here hand held at 1/160th.

I do not know for sure what I will do, but I will definitely carefully look at the outcome of both this and the 100-400, both in weight and quality. I like the flexibility of a zoom, but I love the low weight of my current 100-300 lens. Generally speaking, the weight of the Canon/Nikon lenses was what put me off going to such a system when I went beyond superzoom.

Well, there is nothing like primes....
My E-M1 with the 400+Metabones adapter weighs in at 1.8kg. To get the same reach, with AF AND with IS would cost me close to 4000. That would be a 7DII+100-400 II zoom, which weighs in at 2.5kg. More money, more weight, less IQ.... only real plus is faster AF, but that is a whole new subject I don't want to get into. I am not sold on the 7DII....

For clarity (you might have understood this, but re-reading my post I was not clear): the 100-400 I am talking about is the Pana/Leica one.

very nice, considering the focal length and the small pixel-pitch. I guess without IS a shutter time of Maximum 1/1600 would be necessarey to get fluently sharp Fotos (2x500x1.6)? However birds are moving all the time, so maybe it's better to hold the shutter time Maximum at 1/250.

I wonder: if you need to set the IS manually to 500mm, does this mean, the metabones Adapter doesn't inform the Body about the correct focal length?

Or is it just because of the Extender?

With sensor shift stabilisation, a given degree of twitch will mean that the sensor has to be moved twice as far in the same time when using a lens with double the focal length.
With optical stabilisation, the angular correction needed will be much the same with the longer lens.
There's bound to be some limit at which the available actuators can't move the sensor far enough, fast enough, to keep up with the shake

I use the E-M1 with the Panasonic 100-300 mm. I find zooming out makes it much easier to find the bird, and I typically fully zoom in only after I have located the bird in the viewfinder. I would imagine it can be quite a challenge finding the bird in the viewfinder in the limited field of view that a 400 mm prime lens would provide. Any comment?

[By the way, I expect the rhetoric about in-lens stabilization working better for long lenses has less to do with the facts than appeasing Olympus camera owners who have now been made to wait longer for a lens that will likely be heavier and more expensive than it would have been without such stabilization].

Jim, on my recent trip to Ecuador and Galapagos, I started using my lens at something around 275 instead of 300, because I felt I could actually get visibly sharper images that way.

Off course, in the Galapagos part of the trip, it was frequently necessary to zoom out a lot more, because the birds were that close

Jim,
Yes that is an advantage of zooming, but it is a mater of practice. I have to do it all the time with 840mm of glass attached when I use my scope! I for one would not like to trade the IQ for the convenience, and so far no one has made a zoom that can match primes, especially on the long end.
I made a tiny "sighting tube" that I stick in the flash shoe, even with the 400. On the scope I have a second tube on the far end and it helps a lot!

According to leak reported on m 4/3 rumors, it's 1475g (3.25lbs). Which is slightly more than Nikon and Canon 300mm f4 lenses (and about twice the weight of the new ground breaking ultra light weight Nikon PF 300mm f4)! If that's accurate, this lens has become significantly less appealing. Hope panasonic/leica can do much better with their 400mm zoom. 2600 euro reported price is not appealing either. Says "shipment in March."

http://www.43rumors.com/ft5-olympus-...#disqus_thread

EDIT: Comments to the rumors post say the same German magazine is reporting w/o tripod mount it's 1270g, and that the pana/leica zoom will be 985g (doesn't say whether it's with or w/o tripod mount). If these are accurate, the latter I'd consider, but the former too heavy.

Jim, due to my preference for a zoom if everything else is equal, I was leaning that way anyway. The weights you quote would certainly make that preference stronger
