Originally posted by biz-engineer I've been shooting together with a Nikon user, he used a D810 , a 600 f4 and a 200-400 f4 with TC, both mounted on gimbal and sturdy tripod (40+mm tubes). He also had some shots out of focus with the D810, less then with Pentax, but he still had some shots out of focus. The question is how much is the value of photographs, are those photographs being sold and at what unit price. I could understand that a photographer who is booked for an event or a wedding can't afford to mess up too much with AF. But for wildlife, I don't get the point to want to have 100% keepers, usually, wildlife photography is about knowing repeated behavior and location when animals come in order to have distances appropriate for photography. Repeated behavior means that you have similar opportunities every day. Knowing repeated behavior give a jump of quality of wildlife photographs whatever the camera and lens used. Looking at the big picture, the gear is only a small contributor of success, and the gear is very expensive. We always have the choice between buying top gear and poor subject distance , lighting etc, or spending the money on the quality of the location. I can rent a hide and get outstanding photographs with a K30 and DA55-300, or I can buy a D500 and a 200-500 f5.6 and have to heavily crop all my shots because I did not put efforts into traveling to a great location. You can buy an expensive setup, or you can travel to the Galapagos use your K3 and get full size images of beautiful birds. What I am saying is rational, but there is always someone who catch the virus of buying gear (=desire), that's different.
You could say "I've read the specifications of the D500 and given the reputation of Nikon AF tracking, I was seduced by the D500, now I have the desire to buy and experience the D500, regardless of my photography technique". Then it's a reasonable wish, you will be understood, end of discussion.
While technique and preparation, or learning repeated behaviors, is certainly a crucial component to wildlife photography, sometimes you only get one chance to get the shot. You better have confidence in your gear for that one opportunity!
Example last year:
Snowy Owl comes into the national park for a very short time near me. I get a call from a friend/ranger who tells me they spotted a female.
I drive to the park in January at 4am and hike 5 miles up the beach from the parking lot and finally find her... She's untagged, which means there's NO ONE else around! Incredible experience...
I was able to army crawl up to her over an hours time span as to not spook her and watched and shot a few frames. Trying to be as natural as possible and not disturb her.
Another hour went by, I was hoping to get a flight shot (some people around here will flush the owls to get a flight shot... Just awful...).
I waited and waited and eventually she took off. While I was able to get a lot of still shots of her on the dunes, the flight shots were just horrid.
The lighting was perfect, good contrast, shouldn't have been an issue at all! She took off and I focused and fired, first shot was ehh... each consecutive shot was just embarrassing, like a grown man forgetting how many steps he's walking down and missing the last one only to make a dramatic fall 6" down... That's kind of what it feels like...
Do I blame my gear? Partially. Do I think a Nikon D500 and XXX lens would have done better? No idea... But I'm at the point where these opportunities come few and far between and I'd like to not miss another one.
Maybe the 150-450 would have nailed the flight shots.
Maybe the K-3ii is the weak link.
I can't say for certain... But regardless I was frustrated on my walk back to the car that I missed those shots. Certainly happy with what I was able to experience that day, but those missed opportunities suck, especially when you have a lot of money invested in your gear to perform on days like that.
Repeated behavior does NOT mean you have that opportunity everyday... This was likely a once in a lifetime chance given that she was an untagged owl and I had the beach to myself for such a long time.
