Oh dear for the Tony and Chelsea review....................... I hope they had a dodgy copy!

I don't think the hardware is the biggest problem of the AF misses. Fuji did so much on firmware - if you try an X-T2 with FW 1.00 and one with 4.20, you will experience two very different cameras as soon as you try to make AF-C work. I also hope they stop this stupid closing down aperture to f/5.6 to focus.

But see for yourself: Put your D500 to LiveView and try to focus with AF-F. This is just the kind of experience I was hoping a dedicated "LiveView only" body will not show.

...No matter how many engineers a company has, or how good and long their testing is, many problems will not be fixed (or even spotted) until the product is released and in the hands of people using it to make a living.

I think, Nikon was pushing very hard to make it to the jubilee date of their first FF DSLR, to try to come up with a MILC before Canon does and before photokina. But as you say, they could have taken longer testing periods, the risk of leaking product photos is very high. Rumour sites are on the watch and Nikon shooters waited for very long. I took my time with Fuji, get myself a bit informed and started very small with a X-E2, which now got firmware 4.11, X-T2 is on 4.20, meaning two things: It was well worth the investment, and Fuji messed up a couple of firmwares and needed to develop to this level of performance step by step. So far, Nikon was absolutely shy in terms of delivering new firmware or secure their customers investments.

At the moment Sendai factory makes 20.000 units per month. No matter how big the issues in the pre-production models are, preorders are floating in anyway.

Also, what lenses do you really want in that system? If you are invested in the Nikon F-mount, keep your DSLR for now.

I will keep the DLSRs, but a couple of benefits I hope to get even with Nikon's first attempt - after that, it's better to skip two generations.

If not, wait for Canon's answer.

I'm sceptical if Canon comes up with a flawless first body, a completer lens line - but I'm nearly sure their AF will be better
