Sorry for my spelling!!! You were so observant find it!!!!

Thanks to everyone for there comments!!! It has been very helpful excellent website!!!

I looked at the Tameron and it sounds like a great lens. The reason for the 18-250 is that it is a small lens for travel and general photography. The Tameron is very large to carry around while traveling. Thanks for the reply

You are right, print is my main goal. This all started with a booking of a month long trip to Alaska in July and the desire to upgrade from a point and shoot camera. I am am old SLR film photographer and am amazed by the current state of the technology. I do not think National Geographic will be asking me to join there organization. But as a retired mechanical engineer I have been consumed by the hardware available.

Thanks for the input!!! My main concern is that the "Big Boys" all seam to prefer full frame cameras for image quality. Am I really giving up that much image quality by going to a crop sensor camera? It seems that I gain a lot in lens magnification but at what price?

I am new to wildlife and landscape photograph. After much reading I have come to the conclusion that the ideal solution for me as a armature photographer is a Canon t7i camera with a sigma 18-250 zoom lens and the new canon 100-400 zoom lens. Do to the 1.6 magnification in the crop sensor I will have an effective range of 29 to 640 with two lenses. I am sure there are other solutions and would appreciate hearing the cons to this solution.
