The shot I posted was made on Bruce's D using, I think, an A50/2.0 lens. I don't recall what hood I used with it - probably a normal 50mm hood. The shot was one of the first dozen shots I ever made using a DSLR
With my DS, I always use tighter hoods. For example, for the 50mm I use the hood from a 105mm Takumar, for 35mm I use a 50mm hood, for the 77mm I also use a 105mm hood, although I'm going to try a 135mm hood soon. I've not yet really experimented to see just how tight I can go. I believe with the DSLR a tighter hood than the 105 can be used with the 50mm as that's the hood I use with film, and it doesn't vignette in that case. It's also possible that a tighter hood can be used on the 35mm and certainly the 77mm. OK, I just did a quick test. The hood for the Super-Tak 135/35 works just fine on the 50mm lens, and would, of course, work well on the 77mm. For the 35mm lens I used a generic hood that is the same diameter as the 135mm Super Tak hood, but a little shorter - between the 105mm hood and the 135mm hood in length, and it didn't vignette. So, these initial tests suggest that very tight hoods can be used - tighter than one might think, perhaps.
