I have rented a lens to give it a test drive. Its a super long 100×400 zoom with a 2x extender which allows up to 800mm of length. Here are some initial text photos:
Here is my standard favorite wide angle zoom at 12mm
Here is the same lens at maximum zoom, notice the mountain off the end of the dock and the bouy at the end too.
Test lens at 100 mm
Test lens at 400 mm:
Test lens at maximum length with 2x extender: (See the deer standing mid image below the snow patch?)
Just kidding about the deer! Should be a fun test drive over the next week!!! Stay tuned.
