...this image was taken with tele converter (1.4) at a shutter speed by 1/200 - I think that would not be possible with the A7RIV - normally the high MP cameras need more shutter speed I think....

Finally got out shooting a bit this spring and I discovered some swans nesting about a 1/4 mile from my house. I don't have a ton of extra time to go shooting right now, so I was super excited to find something nearby that I can take photos of.
Yes, it will even fit inside the 20L if you flip up the dividers on one side to allow the lens to take up the entire length. But better is the Travel Backpack with the large camera cube. I recently went on a hike with the lens, camera body, and a macro lens, and while it was heavy, the backpack distributes the weight nicely and was very comfortable throughout the hike. I recommend that setup for this lens.
