Thanks Karin, I finally got.to try the NDF out. Actually I think that shot was with the CP filter (2 secs exposure). The NDF blurred the leaves out too much because of wind. I am going to try and do Brandywine next weekend.

I was disappointed not being able to make it but I did get over to Berea Falls yesterday and met some local photography buffs. They are part of a Facebook group called Cool Photo Ops and Creative Challenges. I joined yesterday. It looks pretty cool, they do field trips around the area and shoot together.

Like others said, you are just cropping your sensor. I have a similar feature on my D7100 which I only use when I burst shoot to help out the small buffer. I don't think you have that problem on the D750.

I feel your pain. I just went through this ordeal trying to decide whether to stay with my Tamron 18-270 mm or buy a brand new Nikon 18-200 vr ii at a reduced cost from my brother. I borrowed the Nikon lens and shot with both. The nikon lens gave sharper pictures across the zoom range. It was barely noticeable in a normal frame but very noticeable at 1:1. The build quality is night and day with Nikon winning. I decided to buy the Nikon.

Before living in Cleveland, I grew up in northern NJ. I remember doing field trips to Catskill Game Farm and then later tubing the Esopus River just north of Kingston.

I have found a wonderful "Old Age" hobby for myself. An outing with some good people to show me some of the ropes you just can't learn reading about would be really good for me. Saturday mornings will never be doable for me though.

Great shots, such a beautiful area. Which one of the many upstate New York lakes is that?? (Tupper, Saranac, Loon, Placid, Cranberry - a few I remember driving from Cleveland to Whiteface)

Some great shots guys!!! Love the one with the walking sticks!! I will fit right in if I can make one of these get togethers. Looks like it was fun (and cold!!).

Thanks, I will try them both out as you stated and see what I think

I have read all the posts (thanks to all). I have learned how to read MTF charts and I have looked at all the comparisons and reviews in DXO, SLRGear, and dpreview. Now I am more confused than ever!!!

Let me lay out the whole scenario. For now I am going to stick with my D7100 with no plans to go full frame in the near future. I do keep the super zoom on my body 90% of the time, mostly for event photography. I change to primes, macro, etc for planned shots. I am an amateur but I am getting better so I want to put decent glass in front of my body.

I have been using a Tamron 18-270 pzi for 3 years. I find it soft (as are most of the super zooms I have been told). I have the opportunity to pick up a Nikon 18-200 dx diII which has never been used for $350 dollars (from my brother who bought it and upgraded to a full frame 2 days after he got the lens). My question now becomes, is the Nikon 18-200 a significant upgrade from the Tamron to purchase it for $350.

I do like the extra reach of the Tamron which is why I wanted to crop the Nikon 18-200 out to 270 to compare the two.

I originally mentioned I had three lenses. I actually found a Nikon 55-200 kit lens out in the woods which was pretty beat up. I found it to be much sharper than the Tamron which is what started this whole process.

Got it Erv. I doubt I can get there before 3 pm but I will call or text and see if you are still there. I want to get over to BW falls eventually to give my 10 stop NDF a try.

The D7100 is a significant upgrade from the D7000 but the difference between the D7200 and D7100 is not as significant (D7200 has a bigger buffer and is slightly better in low light plus has wifi incorportated (which can be added to D7100). I went for the D7100. In those few instances I want burst shots, I change from RAW to jpeg and I can fire away at will.

Very Helpful Jim, that is exactly what I was looking for!!! I will add that to my testing tonight.

I have had the D7100 for a year and I have never had that problem.

I have three lenses I want to compare. They are all telephoto zoom all purpose lenses that I use on a Nikon D7100. I only want to keep one. I won't say which lenses because I am tired of reading about comparisons and have already spent a good bit of time on dpreview. I want to see the differences for myself (maybe I am a control freak!!!).

I can think of tons of shots to set up to compare them but I don't want to spend the next week doing this. What are some standard or lets say "most important types of comparison shots" I should do.

1)Currently, I plan on doing a landscape shot at wide angle and zoom positions on all three at f/8 or so (sweet spot) to compare the best they can do. Then try some high and low f values.

2)The more expensive lens has a shorter reach than the other two so I was going to crop that in post to see how it compares.

3)Low light performance. I have already checked the ability to auto-focus in low light and all three are about the same (even the cheap one) which leads me to believe the D7100 is more important here. I do want to check how the photo's appear though.

4) Some low f value shots to compare Bokeh. Also bokeh on some zoomed shots at highest mm

Any other suggestions or tweaks to the above tests??
