I was fortunate on both of my previous trips in not having a luggage restriction for the first trip(charter group) and bought an extra seat for a group of 4 on the second trip. I have the advantage my wife is not a photographer and will share her baggage allowance. Here is something I am toying with for future trips to reduce weight:
I already own the M5 but would need to sell my 200-400/buy or rent the 400 DO. I could substitute 70-200 f4 II or 70-300 for the 100-400 II. There are always trade offs. The M5 would give me a lightweight EF compatible backup And wide angle solution. My focus is wildlife.
- 1dx II & M5 + EF adaptor (really want a 7d II upgrade)
- 400mm f4 DO IS II, 100-400 II, EF-M 18-150
- 1.4cxTC III & 2x TC III
- Wireless WD passport SSD for backup and iPad Pro instead of a MacBook pro
- 10X30 compact binoculars
- Lightest bag that fits this gear
Thanks for the link beautiful work, well done
Thanks for the comment, you bring up some good points. I borrowed the 400 DO II from CPS for an air show and felt the 400 DO II + 1.4x TC III produced sharper images than the 100-400 II bare. Both lenses were calibrated to my 1dx II with / without TC’s. I am going to go back through the air show photos and compare shutter speeds, aperture, etc to make sure settings are comparable since it was not a structured test.
I will definitely rent or borrow the lens again before I make any decisions. My preference is the flexibility of zooms if I can get the reach, weight and image quality I want.
As regulars to the Bird Portraits and BIF threads know, I am very enthusiastic about both the 400mm DO II and 100-400mm II. Yesterday, I posted some sharp images from the 5DSR + 100-400mm II + 1.4xTC in both threads. The 400mm DO II + 1.4xTCIII is even sharper, and is as sharp as the 100-400mm II at 400mm as found by my experience and the MTFs posted for both on Lenstip. The 400mm DO is tack sharp from edge to edge on FF. My latest copy of the 100-400mm II is very good as well, but an earlier copy was definitely softer. The 400mm DO II really comes into its own with a 2xTC when it is still very sharp at 800mm. If you are going up only to 560mm, then my preference is definitely for the 100-400mm II because the minor sacrifice in IQ is more than compensated for by its flexibility and light weight. But, if you need to squeeze out a useable image from very small birds at medium distances or larger ones far off, then the 400mm DO II + 2xTC is the choice.
Thanks for the comment, very helpful. I notice in your signature you have the Sigma 150-600. I was tempted by this lens (C version, lighter) but the reviews have always made me walk away. Since you have lenses I would consider alternatives, how do you feel about the 150-600?
