Hello all just wanted to get out there and throw my thoughts to the masses about my feelings for the 2 cameras above.
So, lets get this out of the way up front. I'm now the owner of a Nikon D500.
I thought about this long and hard. I'm still a 2 camera camp. I love the m43 for what it does and gives me, and I also love my Nikon kit for the same rationale.
I've never been one to care about size or weight. Performance was always king. If a camera did what I wanted it to, and had the speed to keep up, it would be a winner in my eyes. One of the failings that m43 had was in C-AF performance. While decent, it always seemed to be just a step behind.
Then they announced the EM1 Mk II. From the promises, it seemed that the EM1 Mk II would be the m43 that finally got me where we wanted to be. Then the reviews started coming out from the early releases.
1) They were all portrait and landscape photographers
2) Olympus was talking up the AF and speed performance but not proving - putting their money where their mouth is. This is what is scaring me. If the AF performance is all you say it is, why am I not seeing the proof of this in the hands of all the early testers? Robin Wong tried to show some of it, but he admits, he is not a sports shooter and his examples while decent are something that I know I can already get with the EM1.1
3) The D500 was $300 cheaper and I already have the high performance lenses I need to make the camera sing.
My D300 is getting a little long in the tooth. It still performance decent enough, but I realized that some of the shooting situations, the 70-200/2.8 and ISO 1600(my current usable ceiling for the D300) just are not going to cut it anymore.
I was in the camera store the other day and I was test shooting the D500 with an old 80-200/2.8D lens. Inside I was hand holding at 200mm 1/200, f/2.8, ISO 6400 and the files were clean and the images sharp. Out the door I spent $1700 and they threw in a second battery to boot. Right from the store, the battery had less than half charge. I threw the 70-200/2.8 on it, went out and shot 300 frames with the basic setup(pretty much factory stuff - I still need to dig into the camera manual and fine tune it).
The camera is a beast. Period. End of story. It is flat out the best performing camera I have very used. The AF-S is fast and accurate, the AF-C blew my mind. I pretty much followed my dogs around the dog park, and shot images of them playing. Not sure if you are familiar with how fast little Chihuahua dogs are, but the AF-C kept up with them. The only images that were out of focus were the ones where I just started loosing them from the frame because I physically could not keep up with them.
Without having seen/used an EM1 Mk II I won't say that is it not capable of that. What I will say is that I was willing to save $300 and get a commodity that I was 99% guaranteed would deliver.
Again, don't get me wrong, I love and will continue to use both systems. The EM1 Mk II is not enough of an upgrade to have me hold out for it. The D500 against the D300 and D700 most certainly is worthy of the upgrade. I'm hoping to go out and do some more testing soon. Not sure if I can guarantee more worthy moving targets, but the images I am getting from the camera are spectacular. So far, no regrets.
All sample images here and in the next reply thread were taken with the D500 and the Tamron 70-200/2.8 VC
Here are the dogs!!
