Stick to photography. I'm no ornithologist, but this is NOT a robin!
I prefer the 55-300 over the 70-300mm, having had both.
My advice is to not fool around with all these rub goldberg approaches to create a solution. Instead, as I said earlier, buy the 40mm AF. You will be happy and not have over or under invested!!
If you buy David Busch's Field Guide for the 3200, you will be amazed at how instructive it is!!
I have a Nikon 40mm AF Macro which is 1:1 and I love it. Bought it used on eBay for $200. It is good for still subjects, like coins and stamp collections, but moving subjects like insects, you really need the much pricier 105mm.
A J Richie is gray market. They advertised a D5200 body which was super cheap. Upon questioning I found it had no warentee, no charger, battery or any accessories. 42nd Street was a better buy and was new and not gray and all inclusive.
Check what it costs to add it to your homeowners insurance. Such a rider has no deductible and covers all catastrophes---thief,dropping it, the dog eating it, leaving it in a taxi---you name it. I have $1500 worth of equipment(D5200 body and three lenses) for $29/year with Liberty Mutual. Hard to beat.
Also check your homeowners as a solution. I have a "declaration" on my policy where I detail my three lenses and camera. It provides coverage for lost, damaged, or stolen equipment for about $24 per year for a value of $1300 worth of equipment. It my solution.
No one mentioned the Nikon 55-300mm. I have one and love it!! How do others rate this lens?
"Bad Hair Day" is my favorite. Good depth of field and great subject matter!
Buying a used lens that has been well cared for and is in good condition is a great value and what I always do!
One of the best tips ever given to me before going on an African Safari was to take two identical bodies and two companion telephoto lenses. I was always ready to shot at any time and never had to be concerned about changing lenses in a very dusty environment.
