- First Light by Joe Cornish. No longer in print but this hardcover book is still widely available from resellers on Amazon and AbeBooks.
- Phillip Reeve - A now-multi-author blog with a hugely detailed resource covering manual and vintage lenses, as well as Sony E-mount lenses both old and new.
- Photo Warehouse - 105 Fitzgerald Avenue, Christchurch, New Zealand. Kind enough to do an emergency battery charge for me before I'd acquired a suitable UK->NZ adaptor.
