think you would have to go above that level for decent a/f paul

think you would have to go above that level for decent a/f paul
the trouble is without wanting to sound snobbish ,once you have had a top end camera its hard to go back to lower spec and not miss it
Ok, here are the "test pictures", they were taken today while sitting on a bench..
1. Nikon D3200 + Sigma 150-600mm Contemporary..

Thank you John. Before I explain how I tested this I would like to say that I did manage to find a D3300 and did a similar test.
You used manual mode, essentially telling the camera now to expose, thus having the same exposure from both cameras as expected.
My testing method for you to repeat if you wish :
Both D3200 and D3300 set at:
Matrix metering
Aperture priority
ISO 800
F6.3
When I took a photo with each camera the D3200 decided that the correct speed was 1/400, over exposing the image.
The D3300 chose 1/1000 and the image was correctly exposed.
Thanks,
Michael

Michael, you're right on with your observations, d3200 and d3300 IQ's are different.
Cheers, John
Thank you for confirming this John!
I took lots of shots with a 1.4x tc with the 'C' today as the light was good. I know most folk are probably not interested in shooting at the full 840mm but those that are I attach just one to give you an idea of the IQ. Before anyone pounces on me I am not claiming it is particular sharp or nice image but it may give an idea of the quality loss when using a 1.4x tc with this lens.
Yes 'Ad B' the autofocus works fine as long as you have a Camera that will AF at f8. I have used it on both the 5D3 and 7D2 and AF is good (although slower than the bare lens of course).Hi Roy,
What 1.4 TC do you use?
Did your autofocus work at 600 mm (840 MM)?

Thanks Roy.Yes 'Ad B' the autofocus works fine as long as you have a Camera that will AF at f8. I have used it on both the 5D3 and 7D2 and AF is good (although slower than the bare lens of course).
Note: although the aperture is f9 when you have a 1.4x tc attached the Camera's AF system is fooled into thinking it is still f8 so will AF on the right body (EXIF still shows f9). Metering is also fine as you would expect from TTL metering.
BTW I use a Canon 1.4x tc MkII
