Never ever go on holiday with a brand new untested camera is one of those rules I find myself breaking. Exposure looks ok, the camera tends to select for bigger appertures than I like to compensate for low light. The problem with these shots is AF-auto area mode. I would rather shoot in AF-S Area mode. But I am going to see if its any better with AF-On and AF-C. The result the focus in the photos is not where I want it to be.
Finally figured out how to post photos. These are the shots with "new camera on holiday".
Most of these are shot with Tamron 28-75F2.8 - light and inexpensive lens. I have not figured out how good or sharp this lens is.
Weight issue
For me the choice between the 70-210mmF2.8VRII and the 70-210mmF4VR was simple. Buy the lens that I can hold up with ease to take photos. I stared long and hard at the more expensive 70-210mmF2.8VRII, but at 1.530kg and the weight of the camera at 0.85kg, it would mean that I am holding up 2.38kg to my face. Just not doable if you want to walk around with this lens for me. Also I understand the bokeh reduction from F2.8-4.0 is not significant. I can live slightly less bokeh and 1 stop less. I would rather have a lens that my arms can manage and will actually use, rather have one that I only use when mounted on a tripod at home. I have to take more photos with it before I figure out if I really like it. As for all the technical stuff about how sharp and all that, I do not know. As long as it focuses fast enough, not too heavy, looks sharp in photoshop if I don't mess up the focus point - I am happy, I am not really into the technical comparison of sharpness, IQ and all that.
I think you mean 70-200. 70-210 is from the old days.
Anyway, your pictures look fine. The water lilies one look like it has a slight magenta cast, but I might be mistaken.
Tamron 28-75 is a very sharp lens. I used it for a couple of years. The only issue with that lens is sometimes the AF is not very accurate especially with AF-S. You will do better with that lens when using AF-C.
