I'm thinking of getting a Totech CS-151SS dry cabinet. Does anybody know if a Canon EF 500mm f/4L IS lens will fit on one of its shelves? The Totech data sheet shows internal shelf dimensions of 40cm x 34cm, which means that it's a tight fit. I've attached a figure below showing the scaled lens and shelf geometries. I wonder if internal gizmos for the sliding shelves will cut down the usable space. Also, if there is a shelf at the bottom, can it be removed?
I would buy something bigger if it is that tight and such an inefficient use of space. You might also want to use similar lenses in the future and they may not fit. Why is there the need for the dry cabinet?
My question exactly--I can't understand the need. Packets of dessicant are dirt cheap and do exactly what they're supposed to do, without restricting/limiting storage (they work right in the bags I use in the field.
I have three older alt lenses in the shop getting fungus removed, and I just found another one. None of them had any that I could see when I bought them. None of my Canon EF lenses are currently affected, but I don't want to take any chances. Summer in Halifax is warm and humid.
I agree that desiccant is a solution, but it's not the only one, nor necessarily the best one. Just because you don't understand something doesn't make it bad, it's just something you don't understand.
As far as fit goes, it's not so important for the 500/4, as it's well sealed. As far as getting something bigger goes, it's certainly a good idea; however, as far as I can tell, it represents a significant step up in cost and power consumption, as it's going from 'home' to 'laboratory' technologies.
I was simply asking a question. Maybe somebody out there has the answer.

Sweeeet. But I would invest in some lens caps too. YMMV
All of my lenses have caps. You can see the only two lenses in the case that don't have caps. This is intentional. They're a CZ 135/2.8 and Nikkor 105/1.8 that both have slight amounts of haze on internal elements. I hope to reduce that by drying them out. If it doesn't work, then they're off to the repair centre. Sorry for the confusion.

Some sunlight might help if the drying doesn't do it.
I already "put them on the beach" and it didn't make any difference. Maybe it stopped progress, but that's about it. Also, I often put all of my Alts on the beach for a month or so, and I still have problems. So, now I'll try to eliminate the humidity that they need, in addition to darkness and warmth, at least, not really cold.
