Thank you for the input.
The reason, I was choosing to go with the 70-200mm is mostly for wildlife shots. And also, because the lens received EXCELLENT reviews.
For the most part, I will be in a ground blind of sorts and shooting with the camera, prior to taking my harvest shot during hunting season. Although outside of hunting season it is simply nice to get outside and go for a drive and capture several species while on the road.
I actually discovered this lens thanks to Rifledude. Ted and I went fishing together. It was started out like pulling teeth because I do not like to fish. I thought all fishing was the same. However inevitably I was wrong. I LOVE DEEP SEA and bay fishing. Mostly because you never know what is going to hit the line and there was always some action. One of the best times I have ever experienced and I am truly thankful that Ted included me on the trip. But I'm getting off topic....Now, I discovered this lens on the way back from the trip. Ted and I both went to a local ranch and he was kind enough to allow me to use his lens to shoot with.
Part of the reason why my photos appears so grainy is because my ISO was set on ISO HIGH II, which after some short math Ted discovered was like 24K, needless to say there was a lot of noise on the image. Which isn't bad if I wanted the artistic look like an oil painting. But unfortunately that was not something that I was going for. I wanted a clear image in sharp focus, which is what I would have had, providing I paid closer attention to my settings. But I'm seeing this is a common beginner mistake.
Overall the initial impression that I liked about the 70-200mm F/4 is that the lens extension is internal. Unlike the lens that I currently use. I really enjoyed that feature in particular. Granted I didn't spend a lot of time with it, but what time I did, I really enjoyed using it.
