Is it really true that Z6/7 have a mere two control dials? Like as few as the A6xxxs? I mean I use all four dials and can't bring myself to buy an A6xxx as a backup just for that reason alone.
Nikon seems to be hedging its bets. The projected Canon equipment appears to be part of a much more serious commitment.
I will be keeping some of my Nikon gear, mainly the D500 and the longer lenses for sports/BIF shooting.
There you go. Perfect. If I had a D500 I would keep it and a few appropriate lenses as well. Make sure you save a normal zoom and a fast prime as well - just in case.
Yeah, the D500 is pretty remarkable for sports/BIF shooting and with the larger lenses I wouldn't want a smaller ML body anyway, as it just isn't comfortable. Haven't had a Nikon DX zoom though since about 7 years ago, until just last month (I am a prime guy) when bought the Tokina 11-16 DX f2.8 zoom. I will most definitely keep that, along with the 70-200VR f2.8, 300mm f4 and the TC-14. That way with the TC and and 300mm I can effectively have a AF 630mm f5.6. I have a bunch of Nikkor FF primes, both MF and AF, but I haven't sorted out what I will be keeping yet, as it will really depends upon on how good I find the Sony. The better the Sony is, the less Nikon gear I will keep. Besides the 3 FE primes I purchased, listed in my sig, I plan on adding the Zeiss Batis 18mm f2.8 and 135mm f2.8, once the Holiday sales start.
One thing I haven't seen in the Sony FE system is a 300mm f4. Have you seen any info/rumors on one coming up?
I think the only tele prime they've done past 135mm is the 400/2.8. The rest are zooms (70-200, 70-300, 100-400)
You can get the Viltrox NF-E1 Nikon to Sony adapter and it works okay with the Nikon 300mm f4 AFS and the A7III. Not native fast, but in good light it does lock-on decently. It might hold you over until you get a solid telephoto on the Sony side.
