| Mid-May Countryside: Canon40D-EF28-135mm f/3.5-5.6 IS USM | 
Mid-May,
 and most trees and shrubs are in full leaf.  It seems only a short time
 ago that the countryside was drab and brown. The whitetail deer are 
very ragged looking as the thick, brown,winter coats slowly give way to 
the thin, red hair of summer.  Within a few weeks these animals will be 
sleek, beautiful creatures once again.

| Young Doe With Ragged Winter Coat: Canon 5D Mark III-Canon 24-105mm F4 IS L | 
The does are in the late stages of 
pregnancy and a few of the fawns have already been born, although I have
 not yet seen any.  The local herd does not usually have their fawns 
until the last few days of May, with the vast majority being born in 
early to mid- June.  The first fawn sightings are always a special 
thrill.

| Adult Does: Canon 40D-Canon EF 17-40mm f/4L USM | 
While the does are getting ready to give birth, the 
turkeys are still engaged in mating activity, but one is not nearly so 
likely to see a mature gobbler strutting as they were a few weeks ago. 
Rather one may flush them while walking through the woodlands or see 
them as they feed in the meadows.

| Young Gobblers a.k.a. "Jakes": Canon 5D Mark III- Canon 300mm f/2.8L IS USM | 
But sometimes one is lucky enough to see a mature 
gobbler in full courtship display.  Almost invariably there is a hen 
feeding nearby and the gobbler usually struts as long as she remains in 
the area.

| Mature Gobbler Strutting: Panasonic GH3-LUMIX G- 100-300/F4.0-5.6 @ 300mm | 
While I usually use the 5D MK III and the 
7D for still photography and the Panasonic GH3 for video, I find I the 
GH3 is also very good for still photography and is much better in that 
respect than its' predecessor the GH2. The GH3 has a 2X crop factor 
compared to a full frame sensor camera so the 100-300 is the equivalent 
of a 200-600mm zoom on the 5D MK III. It is not as tack sharp and has 
more distortion, etc., but l it is still a very usable lens.  The 
gobbler was quite a distance away and I cropped the image  
significantly  to make this photo.  Unfortunately I did not have the 5D 
MK III with the 500mm lens set up on a tripod, as I would have liked to 
get some shots with it to have a good comparison of quality, but the 
bird did not tolerate me getting this rig into shooting position and 
left the meadow.  I also would have liked to had the 500mm on the 
Panasonic for this photo, but I selected the 100-300mm when I set up 
that evening as I was concentrating on capturing video and wanted a lens
 that was capable of covering a wide range of situations.  As it was I 
got a decent portrait of the gobbler and many very satisfactory video 
clips.
