Buffer upgrade? What's wrong with the standard buffer?

Nothing but having the extra buffer is useful for sports or wildlife if you like to machine gun your subject.
I use it very occasionally on the D3S which comes with the extra buffer as standard.
The D3S has a quiet mode as well which reduces the noise of the shutter and a sensor self clean. Like I say all the bells and whistles found in the latest releases of cameras.

That doesn't sound like a problem then. Two or three quick exposures maybe but not more than that. Digital film maybe cheap but there is no need to waste it!

The sensor self clean is a miss. I'm thinking of sending my D3 in for a service to get it as clean as possible.

Had a long chat to Nikon NPS today told them my problems with the D810 and auto focus (for bird photography) with my new 500mm AF-S f4 and I was keen to get a D5. I now think with new info that the D500 will be the camera for me and will save me money too! The auto focus he told me is as fast and as good as the D5 as is the fast ISO quality.

Graham, effectively the AF is much better on the D500 because the AF sensor array area almost covers the entire DX frame, whereas on the D5 it's pretty centralised because the AF sensor array area is the same size as the D500 but the frame area is bigger because it's FX.

There are diagrams on the 'net which explain it but I am sure you get the picture!

I need to look carefully at the D500 but I want a facility that allows me to 'lock' the shutter speed and/or aperture like on my D3. I find on lesser cameras I tend to move the dials when shooting as I move my hand.

I know the D800/810 has it in the menus.
Does the D750 and/or D500?

Very close to thinking I will get one. It will be ideal for bird photography with my 500mm f4 lens, the new auto focus will help a lot and with the D810 I find most of the time I have to crop so DX will be no problem!

Have the left out the low pass filter? I hope so as it has been no problem with the D810 and far less unsharp masking in post production is only good news!

I found this a good read.

I can't find mention of an AA filter on the D500 but all DSLR's need some sort of protective glass in front of the sensor. Otherwise the image suffers distortion and focus issues. The question is whether the glass is clear or not, dipped in acid to produce a very slightly rippled surface sufficient to prevent aliasing of repetitive lines in an image.

https://en.wikipedia.org/wiki/Anti-aliasing_filter

There also of course needs to be a low pass filter which restricts the wavelengths of light able to reach the sensor to the visible range, filtering out anything below about 400nm or above 680-700nm. Otherwise you just get a blurred mess with focus shift and IR-UV contamination.

My understanding with these higher resolution sensors is that the frequencies involved are less susceptible to the problem of aliasing in real life use but I think Nikon have recognised they need to be light handed in this department now, I doubt they would go back to the strength of filters used in the D200 for example.

I think now this particular aspect of imaging design is better understood and better catered for. If there is some AA effect filter in the D500 I doubt it will be detrimental. There is a far greater mission to create the ultimate resolution image now rather than trying to minimise perceived issues which rarely existed.
