This morning I had another opportunity for testing the older Canon EF 100-400mm f/4.5-5.6L IS USM lens along the Diep River and the Table Bay Nature Reserve at Woodbridge Island.

I'm still trying to find the best body / lens combination for my Kirstenbosch National Botanical Garden, Cape Town small bird and flower photography.

My Canon EF 400mm f/5.6L USM lens my preferred go-to lens, but it is rather limited as a prime / non-zoom 400mm lens for my shooting requirements at Kirstenbosch. 

Canon DSLR vs Sony Compact Camera for my Kirstenbosch Photography Decision
Currently I am looking at my Canon EOS 70D or a new Canon EOS 90D body to pair with this (used) Canon EF 100-400mm lens. Another serious consideration is the possible addition of my first Sony camera - the Sony RX10 IV compact / bridge camera with ZEISS® Vario-Sonnar T* 24-600mm  f/2.4 - f/4 optical zoom lens. 

I've done a fair amount of research on the Sony RX10 IV and am really impressed with the optical performance of the 25x optical zoom lens, image quality and continuous shooting speed. This non-DSLR Sony bridge camera may just be the ultimate (travel) solution for photographing a variety of architecture, birds, flowers, landscapes and plant images between the very appealing 24-600mm focal length range.

Canon Camera / Lens used at Woodbridge Island: 
  • Canon EOS 70D
  • Canon EF 100-400mm f/4.5-5.6L IS USM Lens (Mark I)
