Elastic rulers?

Have any of you looked at the dimensions quoted for Pentax lenses?

I mean diameter and length.

I have been trying to use published Pentax lens data to work out how big a waterproof Peli style box I might need, but during the process found that either my lenses have grown or Pentax can't measure!

As an example, a DA70mm f2.4 Limited is quoted as being 1"/26mm long. Really? Lots of other examples that I won't bore you all with.

Anyone know a reliable source for such data, or is it just down to me and a ruler?

A ruler is a great idea, but are you sure the 70mm isn't 26mm? When you take off the lens hood it might very well be?

26mm is the length of the lens body, not including mount or hood. The mount depth will be standard but the hood will vary, if you usually keep it attached (which I suppose we all do for lenses with that style of hood).

Thanks guys.

Maybe you're right, but I don't remove lens mounts, etc. in order to stow my gear.

If I have a lens hood that's reversible, that's what I do. I can't see any benefit whatever in giving dimensions for the bit in the middle that is next to useless without the bits on each end! Even if I don't use the lens hood, (and I'm not sure how easy it would be to remove it from the 70), the mount must count in the overall length surely?

And who wants to use a lens without it's hood?

Just for comparison I just measured a Sigma lens. Once again the quoted length excludes the mount and hood.

The old Lowepro Omni (Sport, Traveler (sic), Trecker, ) series all fitted into specific peli cases. The sport has a shoulder strap and belt and mine carries, K-5 with Tamron 17-50, 55-300, DAL35 and DAL50, and some odds and sods.

There may be similar cases available today. The Omni's come up on ebay occasionally and the biggest with a peli (or Lowepro branded version) go for a reasonable price.

Thanks Philip. Maybe it's a Japanese thing?

Thanks Doug. I'm after something specific to transport my shed load of lenses along on top of a fishing tackle trolley.

My kit is way too heavy to carry in a back-pack for any length of time, (not that anyone makes one big enough, and since I never know what I might be photography when I'm out and about I always take everything, including a kitchen sink or too!! As ever, though, I find I only use one or two lenses.

It's the curse of LBA; as I've got 'em I want to take 'em! Wouldn't be so bad if I actually made decent photo's!

John, the dividers are adjustable.

Yum yum

Very useful back in the early days of wet plate photography but modern film will wait till you get home...
