We have clever Gulls round these parts. They can read!

What do uploaded images not look as good as they do when I view them locally?

I lied. They can't read for toffees.

Having thought about an issue I'm having!

Is there a correlation between subject distances and camera shake?
In other words, do you/I need a higher shutter speed to negate camera movement when subjects are a long way off?

I think it is commonly believed that the site software does have an effect on image quality although that may only be for pictures that the "site software" resizes. As an aside, I do know the software I use to resize pictures before posting does affect image quality.

Thinking about it, one could post a full size picture for the site to process and post the same picture resized locally to compare image quality.

I don't know what "theory" says. In my own experience (66 years old with a bit of shaky hands), camera shake effect is the same whether near or far. Rob mentioned earlier that atmosphere can have an adverse effect. I've seen that many, many times. Here's an example taken with a 1DX2 + 100-400 II (the blurriness is all due to atmosphere). The photo distance is similar to your 400 yards away.

Here's the rub.

With a 100-400 mk2 attached all is well until I try to focus on subjects close to infinity (looking at the lens markings)
The camera says it's focused and I'm sure it is but, the images look smudged and I can't find anything that is critically sharp.

The shutter speed is high enough and it does not look like a front/back focus issue.

I'll post some examples when time permits but for now, if anyone can cobble together a 100-400 with 1dx3 and fire off a couple of shots close to infinity that would be great.

In terms of distance I would estimate in excess of 400 yards.

I replaced a 300 2.8 II with the 100-400 II five years ago. I'm totally happy with the 100-400 II (with or without the 1.4x III). It's been great on my 1DX2. I have a 1DX3 on order. It shipped today and will be here Wednesday. I'll be posting results here.

One of my favorite features is the opposite of infinity focus. The 100-400 II focuses at 3 feet even with the 1.4x III on it. 560mm at 3 feet! It's great for pseudo-macro when you just happen to see something.

I'm interested in how the 100-400 II/1.4x combo works on the 1DX3 as compared to the 1DX2, in terms of AF performance.

Looking forward to your comments.

Af speed with 100-400 and 1.4X is very good, about the same as a 1dx2.
The main difference with the 1dx3 is that it locks on faster and tracks better (IMO)

It seems more accurate and repeatable too (Ref OVF)

The further away any given subject is, the larger the streak of blur from camera motion will be, relative to the subject size. The size of the streak relative to the sensor size has nothing to do with distance, and is based on sensor size and focal length.

Well, I started getting the Error 70 again using the Sony Card. I'm working with the local camera shop where I purchased camera and card. They've gotten Canon and Sony involved. Hopefully we can get a resolution. Is anyone else here having this issue besides Kickflipkid687?

I have never got an error. I use both Sandisk and Sony cards. The only issued I have had is it locked up during a burst while in Florida on a trip. I had to pull the battery and good to go. Since the new firmware no issues.
