...
Would the setup work with the m4/3 MC14 (not 4/3 EC14) between camera body and Metabones? (As an alternative to Canon TC)

I should think it would. Don't see why not. It might be worth a mail to Metabones to ask, but I doubt they would answer....

Hi

very nice photos!

These 2 Adapters don't fit with each other, however the quality of the TC-14 seems to be very good referring to this post:

Got the adapter today. ...2. AF works VERY WELL, not blazing fast, but it is very accurate. The 50-200 + EC-14 is still faster, but it is f4.9 vs f5.6, and that makes a big difference.

I found the EC-20 to be too soft to be of much benefit, where the EC-14 it top notch.
A 400mm prime is always going to beat a zoom at the same focal length, especially with a TC attached. Certainly the Canon 400 is better at 400 than their own new 100-400.

thank you for sharing all those Information here. Do you also participate on the site www.dslr-forum.de?

If you don't mind, I would like to aks you some questions:

I wonder if you can use all functions of the E-M1, even all Focus functions and Focus Points if you adapt the 400mm lens to your E-M1?

Does the IBIS work worse/equal/better with the 400mm lens compared to the 50-200 + EC-20 @ 400mm?

If you use the EF 400mm Lens @ f/5.6, is the sharpness and contrast always better, compared to the 50-200 + EC-20, even if it is stopped down to f/9 or f/10?

your reply is highly appreciated, thank you.

Dan, the adapter you are using, is that a speed-booster type adapter or something else?

Niels, no, NOT the Speed booster!! The Smart Adapter MB_EF-m34-BM1
Allouette,
The IBIS works VERY well, every bit as good as the 50-200 or any other. As you can see from my samples, I can hand hold at 1/60 with 400-540mm of glass!

Today I played around with the 400/5.6 with the 1.4 Extender attached in only slightly better light. It works VERY WELL. Amazing what a little light will do!


Even with the extender attached I have the whole center group of 37 AF points if I need them, and they all work. (The 7DII has ONE!)

You can use all functions on the E-M1, with the exception of C-AF. It sort of works when there is enough light, but it is not yet there. It wouldn't surprise me that Metabones makes improvements there. Hope so.

In my opinion the 50-200 + EC-20 can't come close to the 400/5.6 prime, even stopped down. I had the EC-20 and got rid of it. The EC-14 is excellent, but I found the EC-20 not so good. The 50-200 is a wonderful lens, but up-resed files from it with the EC-14 are far inferior to the 400/5.6. Hard to beat primes and the little Canon 400/5.6 is a gem!

Hi Dan

thank you for all this Information :t:
I made similar experience: EC-20 doesn't work very well with my old 50-200. Stopped down to f/9.00 is ok, but not really good. I made a comparison between the ZD 300/2.8 + EC-14 and the ZD 50-200+ EC-20 some days ago.

Your last 3 pics look amazingly sharp, hower it's on a recuded size. A Crop says more than 1000 words

Since I got the good News from Horst on dslr-forum.de I'm looking for a used 400mm f/5.6. However if I had the money, I would buy a 100-400mm II because it's much more versatile and referring to the test on photozone.de it's even sharper in the Center than the 400mm f/5.6.

Because I do more Wildlife I wonder if you have any photo (crop 100%) taken on a bigger Distance of 15-30meters. Use of tripod is recommended. Referring to the test on Photozone.de the 400mm f/5.6 seems to suffer from CA's. Have you noticed any problems with high-contrasty objects?

cheers

[DanC.Licks]

There is sometimes some CA when used with the Extender. Sometimes a little can be seen without, but nothing serious.
Don't agree that the new 100-400 is sharper than the 400 prime.
http://www.the-digital-picture.com/...meraComp=453&SampleComp=0&FLIComp=4&APIComp=1

Still, the 100-400 II is a very fine lens, and if I were to buy into Canon, that is what I would get. As is, I have the 50-200, the EC-14, the mFT 75-300 II and the 14-54 FT II. My main lens (when I can transport it) is a 600mm telescope, and it beats the whole lot by a mile!

Here is a crop and the full sized shot, with the 400/5.6 wide open.

 

[alouette_]

Thank you Daniel for the additional information and the Crop.

Yes, it looks very sharp. However I believe on a close distance like this, optical weakining in general is not a big problem, at least I have done this experience with the ZD 300 + EC-20. As farer the object away, as bigger the optical Problems.

Neverthless I have ordered an used Canon 400mm f/5.6 Lens just few minutes ago B

At the Moment I don't have the Metabones Adapter, because I want the BT2 Version. I probably will order it directly from the USA including a Lenscoat for the 400mm Lens.

By the way. do you use your lens on a Tripodhead? I wonder, if there is a suitable, lightweight swiss-arca plate, fitting perfectly for this lens.

cheers

[DanC.Licks]

No real difference between the BT2 and the BM1 as far as function is concerned. I only use this lens hand held, or supported on a special monopod I made that supports the front end of the lens, just behind the hood. I don't like monopods fixed to the lens collar.
Don't confuse air with optical performance. A little too much air can make the best lens look crappy. Closer is always better! Long lenses are always corrected for distance, so if they are sharp close up they will be sharp at distance. Air is our worst enemy!
Now, about CA.... see any here?

Hand held with the 400+1.4 Extender III and AF.

I would say the oposite: if the sharp on the distance, they are sharp Close up

Talking about the optical problems with the EC-20, I'm quite sure, the problems occur not through the air. The ZD 50-200 and 300/2.8 don't seem to have any problem with the air, except you use them Close over a warm ground.

Now, about CA.... see any here?

Looks impressiv, but are you brave enough to post a 100% Crop?

 

[DanC.Licks]

Not worth it. It is just a point and shoot shot to show CA. If you don't see any on moon shots, you are in good shape.
Here is what the 600mm scope + EC-14 can do, taken just a few minuets later:

Air was not so good last night. This was on a better night, without any TC attached.

[DanC.Licks]

See here regarding BIF:
http://forum.fourthirdsphoto.com/threads/77136-Metabones-Smart-Adapter?p=638041#post638041

In short....works great!

 

[alouette_]

thank you, that 600mm lens produce a great Job!

But back to the 40/5.6: did you have to remove CA's with the bigger "birds" in flight (postet in the indicated forum)?

 

[DanC.Licks]

Here you can see for yourself:



CA is naturally more noticeable when something is not in focus, or, as in the Emirates Airbus 380, there is too much air in between to provide sharp contours.

 

[Tord]

...

and if the camera is on a tripod.... forget it.

Since the lens has a rotating lens collar, rotating the camera between landscape and portrait mode is done in a matter of 2 seconds. Starting from portrait as default mode for BIF and in the rare situations the subject will fill too much of the frame revert to landscape to reduce risk of bad framing.

Changing your mind in the middle of a sequence is not something you want to do, though.

 

[DanC.Licks]

I was talking about the problems with having to twist the camera 45° to focus and then re-frame for the shot. I guess if the collar rotates easily it wouldn't be so much different than hand holding. Cross type or even double cross type AF points is the answer, but alas, we don't have them.

Quick AF test on the moon last night. Nine shots with re-focusing each time:


ISO 200, 1/100 at f/9, 400+1.4x TC, hand held but resting the camera against the window frame. Air was not great....

 

[DanC.Licks]

Putting things into perspective I did a quick indoor test of the Canon 400/5.6+ 1.4x Extender III against my 90/600 triplet scope. Distance about 9 meters.
See if you can guess which is which

 

[DanC.Licks]

And here, 3 meters closer without the TC:

I wouldn't go anywhere withouth the 90/600. If you want it to retire, there is a nursing home just south of Stockholm.... ;-)

I would guess that the second, sharper image is the scope
