New Teleconverter test

Two weeks out from heading out west on our National Park vacation.  Decided to pull the trigger on the Canon RF 2X Teleconverter to complete the last missing piece of the big glass.

The following three test photos were shot at 50 yards, as measured with my golf laser range finder.  My teddy bear model is the same size as an Great Horned Owl or a small Bear’s head.  The rule of thumb in the national parks is NO closer than 50 yards from the wildlife.

Canon R5MK2 + Canon RF600 f4 = 600mm f4

Canon R5MK2 + Canon RF600 f4 + Canon RF 1.4 Teleconverter = 840mm f5.6

Canon R5MK2 + Canon RF600 f4 + Canon RF 2X Teleconverter = 1200mm f8

Doesn’t look like I’ll be giving up much sharpness withe either TC is there is adequate lighting.  

Here is an old review were I used the same teddy bear model: https://kentjarrett.com/2015/01/15/focussharpness/

2025 Spring Great Smoky Mountains National Park (GSMNP)

My sister (Deb) and her husband (Dave) go to the Smokey Mountains 3 or 4 times a year and have been going for over 50 years.  It is one of their happy places!  They own a time share there, as well as their 40’ RV.  Just about every year they go for all of April for her wildflowers.  This year I decided to drag our travel trailer out to meet them for a week (4/22 – 4/29).  I was more about photographing the Black Bears and the spring cubs.  Once the moms bring the cubs out of their winter dens, it is easier to find them due to the fact that the little cubs can only travel so far.   I am good friends with several of the local photographers that knew where the winter dens were and was lucky enough to find 4 or 5 sets of cubs.
