D610 or D750

I did not know that they were doing all of them even without problems. Just like the parent company, Mitsubishi, they are so slow to adapt. Glad they are doing the right thing here finally. Makes me want to get a spare...

It is indeed a vicious circle, no matter how good my raptor images are, the raptors don't really care and never offer to pay me...

Those bastards! Lol

I personally would say the D750 is a better fit for you. When you want to shoot wildlife the d600/10 AF is not as good as the newer AF in the D750 for tracking. There was a deal on refurb D750 that popped up 2 weeks ago for 1400, maybe it will come back again.. The other problem you have is your lens for wildlife will need to be longer also..

Yup, the better af system can make a world of difference.

Tested my D600 earlier today. So far, so good. Very clean images, now.

Hmmm, lot of food for thought. Thanks guys!

Last year, I attempted shooting superbike racing with my 20+ year old Nikkor 300 f4. The autofocus from the body was too slow. This year, I returned with the new sigma, and the autofocus exceeded expectations!
I have read that the 750's AF is a next-gen system and much improved.
All comes down to budget. Here's some race pics: VIR_3168

The Nikon 300/4 AF. I had that lens.

The focus throw was designed more for manual use than the AF systems of today. The long focus throw provides accurate manual focusing. But requires more time, and more revolutions of the screw drive for the focusing system. The more modern lenses have very short throws in comparison to the older lenses, thus they focus faster .. optimized for auto focusing. Plus the newer in-lens focusing motors provide very fast focusing with the short throws.

If you want slow, try a 75-300 AF lens by comparison.

Really loved my 300mm f4.
Yea, kinda slow, but an absolute tank of a lens. One of the lenses I regret selling.

exact same one I had. I bought the 300/4 after I had a 70-300VR "I don't like low contrast targets" lens. I used it some but really needed a zoom for a one camera sports lens. Went up to a Bigma then the Tamrom 150-600.

I loved the starbursts at f/8 and higher with that lens' 9 straight blades.

I'm gonna say neither. Get the D500
