Well, I have never been able to reel off 17 images before the camera has prevented me continuing to capture.

So what is it with lossless compression? It is called lossless because not a single bit of information is lost. Anyway, the buffer size is 16 raw for uncompressed images if you absolutely must shoot uncompressed, but that is pointless in my opinion because it adds nothing else than increased file size.

Again, I have had no luck squeezing out 16 or 17 raws.

There must be something wrong with your camera. I measured mine and mine is according to the specs. No doubt about that.

However there are several things which may reduce your buffer depth...

Lossless compression is not resulting in equal file sizes for every scene, just approximately. ADL, as well as high ISO NR reduces buffer size and a few other things. All described on pages 436-438 of the manual.

In which way Canon raw "offers more options" than Nikon NEF?

They offer SRAW, which is very popular with wedding shooters because it's pretty small.

"Pretty small" compared to what? Compressed vs. uncompressed Canon RAW? I thought you were against compression. If compressed files is what you want then you can use the "Compressed NEF" option, which would give you another 4 images extra in the buffer. If reduced quality is OK, 12-bit compressed NEF will give you a buffer size of 25 images. Is that still not enough? How large is the 5D3 buffer and what is the adavantages of SRAW? You said SRAW offers more options, what more apart from the size and what size is an SRAW image actually?

Of course the 5D3 files are smaller. Less MP = smaller files. How easily the camera can cope with the file size depends on much more than the file size, processor, transfer speed, memory speed and so on are all related to that, not just the file size.

I agree, but it's one important factor.  I read somewhere that the Digic 5 is faster than the Expseed 3,  that is the other factor.

If fps and buffer size is that important I would not chose the D800 or the 5D3. I really don't believe 1 extra frame is a deal breaker for anyone.
