No, it can't be! Look at the shadow on the wooden fence and the leaves on the bush. It might be a stuffed parrot though :-P Or maybe everything in Oz is upside down just like people say ;-)a

Indeed, the photo is right side up, it's the location that is upside down.
In fact that is the first image that he HASN'T turned upside down, he just forget to do it this time.

I was wondering how the 1.4x Mark II extender affected the image quality of the 100-400 MkII so I took a couple of images of the same Woodpigeon and created this composite.

The main image is the 100-400 + 1.4x and is pretty good. The clip of the bird at 400mm (top left) shows the difference in focal length. I then expanded the shot at 400mm so the bird was the same size as the 560mm shot (top right).

I then had a look at the bird's head in more detail (bottom row).

It looks as though the 1.4x has minimal negative effect on the image and that the 400mm and 560mm images can be blown up to give very similar images. I'm now in a bit of a quandary trying to decide when the use of the 1.4x would give me a better image. Does anyone have any real world experience of when the extender is useful.

I would say...the 1.4xTC gives the:

- 5DSR the greatest actual benefit without any IQ hit except for atmospherics compression which can be better seen and defined because of the resolution detail, so you know what the hit is, for example nicely defined heat shimmer.

- 7D2 gets the greatest perceived benefit in terms of reach

- 5D3 gets a nice reach and detail benefit

Al three are more likely to get hit by the consequences of f/8 in terms of shutter speed and ISO noise, though the 5DSR will eek out more detail ameliorating noise.

The 2xTC gives you less of an optical hit and more the consequences of f/11.

How the TC shines is more a matter of what you are shooting at what distance in my experience

You are lucky. I had to MFA my 1.4 III to +14 @400mm. I'm getting good IQ but I did wonder why. After reading the following article I tried it with my 300 L F4 IS and only got a difference of +1 with it on and off so it is not the TC. Without the TC the 100-400 @ 400 only needs +3.

Even though Canon says the 100-400 is compatible the author states that TC's are tuned for long primes. I guess with all those elements and the zooming something out a bit can get exploited a lot with a TC. I'd like to understand it better but have not found anything else on it.
