I've been on three and the most important advice I can share is to take two bodies. This means no lens changes and provides backup in case one fails. Dust may be an issue as well so not changing lens not only is a convenience, but a necessity!

CORRECTION: 18-140mm not 18-70mm. I liked the walk-around aspects of the 18-140mm enough to interest me in the 18-300!!

I currently have a Nikon D 5200 and a Nikon18-300mm lens in a brown truck circling Louisville. I sold my 18-70 and 55-300mm locally. The same buyer will buy my D5200, making my net cost to buy a D 5500 $330. Question: is the upgrade to a D 5500 worth it? And, did I make the right move going to an 18-300mm? (I shoot wildlife and grandkids.)

Take two like bodies for two lenses. Changing lenses in that environment is not a good idea!

I went on that trip last year with International Expositions. I rarely used my 55-300mm---my 18-140mm was my primary lens. You'll shoot lots
of close ups of spiders, frogs, snakes, birds and people in villages. The jungle is thick so distant shots are rare.

I have the Nikon 40mm and am very happy with it. It is the value performer---crisp pictures and relatively inexpensive. The only downside, as previously stated, is that insects tend to fly away before you can set up to shoot. Still shots, however, are great!

Curious---why not the 5500 instead of the 5300?

You are absolutely correct

Great shots, but I think your butterfly is a moth.

As the originator of this post, I'm very surprised at the raucous I have stirred up. There certainly have been a lot of varying response---and lots of them.. I like and respect Adorama, I was merely stating that their return policy needed to be revisited as it is unfair to the buyer of inexpensive merchandise. I continue to firmly believe this. Thanks to everyone for weighing in on this.

I purchased a Sunpak Quanaray tripod from Adorama. It was on sale for $40 from $100, with free shipping. Upon receiving it, I determined that it wasn't suitable for my purposes -- it weighed over 6 pounds. Adorama's return policy, which they tout to be the best in the business, calls for their normal shipping charge to be deducted from the refund on items that were sold with free shipping. In my case that meant that I paid $18 for return shipping and they deducted another $17 for their normal shipping charge. Net, net, I got $5 of my $40 returned to me. I don't think that qualifies as the best return policy in the business. In fact, I think it STINKS!
Has any one else had this experience?

It can be very dusty. I advise two bodies and two complementary lenses and never plan on switching lenses. That's what I did and it worked great. I used a 55-300mm and an 18-70mm. I used both a lot. The game is generally quite close.

Thanks for all the helpful insight.

I normally shoot nature pictures and love my Nikon 55-300mm on my D5200. However, I just returned from a European trip and found I primarily used my 18-70mm lens as we were on walking tours. It gave new meaning to "walk-around-lens" for me. Accordingly, I'm now interested in upgrading to an 18-140mm for more versitility. I would appreciate any comments on this lens as a replacement for my 18-70mm. Thanks.

The important issue is what is the significance of the count once you know it? I.e.,how many clicks is too many when you are purchasing used?
