Hi there

 

Wow, it's really long, isn't it?

 

And what's more, it gets longer as the focal length extends. So, you realise the shot isn't tight enough, pull the 35, which has a 2'8" MOD, and put on the 50. Which has a 3'6" MOD. So you move back, and you realise you've achieved... er, more or less the same frame. So you grab the 70. Oh, dear. Four and a bit feet.

 

Unfortunately, I didn't have any diopters of a suitable diameter, but I'd have been a bit alarmed at the prospect of even more distortion and softness.

Yeah, but... but the lovely flares and wonky corners.

The close focus really depends on the lens set - I'm assuming you were using the SLR Magic 1.33x lenses. But in general, you're right that it is a common issue with anamorphics, so it's common practice to always add a set of diopters and sometimes a particular macro lens.

 

Tiffen sells a set of single-element diopters (+1, +2, +4) in the common screw-in sizes that isn't too expensive and work well. Much more affordable than a set of 4.5" or 138mm round diopters, and easy to tape onto the front of a small diameter lens like the SLR Magics (not sure if they have filter threads now, the early production models I've seen did not have them). The set is missing a +0.5 and is not as sharp as a set of achromats, but for most macro work you can add light and simply stop down. That's what I use with my Iscorama.

Yes. Considering they're more or less made out of a stack of adapters anyway, I would have hated to add a diopter.

Meh, they are still way sharper than a set of Kowas, and look at all the projects shot on those! Some of those old scope lenses are crazy soft wide open. You would call them rubbish, I'm sure. Plus, close focus is where you really start to see a lot of the anamorphic artifacts that people like so much.
