Take a look at Zeiss HT42. Compared with the prior model, the FL, Zeiss moved the focus wheel from the top of the hinge, split the hinge in two, creating two bridges, and put the focus wheel between the two bridges. This was a significant step both aesthetically and ergonomically. This feature of HT was adopted by SF with the addition of a third bridge and with all three bridges more gracefully integrated into the overall design. So with SF's triple bridge and focus wheel sited between the top two bridges I have difficulty in thinking SF looks anything like Swarovski's EL42 with it's focus wheel on top of the hinge and only two bridges. The only common aspect is the bridge by the objective but even these couldn't be more different with the Swaro's chunky bridge looking quite distinct from the SF's upward curving 'moustache' bridge. Once you step back and look at HT you realise that SF was a logical development of HT and of course came with a weight distribution that added significantly to the success of its ergonomics.
Now, NL discarded the objective bridge, and it does have a focus wheel moved from the top of the hinge, but I am struggling to see any resemblence to HT as NL still has a one piece hinge and bridge, has those slim-line waists, not to mention those hideous knobs on the side for strap attachment.
