the important stuff

Another question I came up is: What is the maximum weight of a lens for a camera mount? The L-mount for instance.

The Elmarit 280mm is too heavy to be carried by an R-mount, warns Leica. That lens is around 2.5 kilo.

I keep a spreadsheet of my camera gear for different reasons...insurance in case of fire or other damage, for my executor at the appropriate time so she ha a list of all the pieces, and finally for myself to keep track of the bits and pieces, which seem to have gotten out of hand in recent years🤣, with boxes in the storage area of my garage, bodies and lenses in 6 different places, and so on. I also put on there acquisition dates and prices asd seale dates and prices so I know how to deal with the tax man each year. Glad to know I'm not the only geek keeping camera spreadsheets.

I have a spreadsheet just for filters…

Due to my increasing decrepitness I have a chart of the weight of all bodies and lenses to better judge what combination(s) might be feasible on any given day.  An SL2 will never grace my camera bag...  

[BradS]

I have a spread sheet that includes the weights of my backpacking gear but the document that I keep of my camera gear does not include weights.

Spread sheet? Good Lord, no!

I have them memorized.

21mm Elmarit-M - 257g
28mm Elmarit-M v.4 - 244g
35mm Summilux-M v.2 - 160g
75mm Nokton f/1.5 - 337g
75mm ASMA (APO-Summicron-M-ASPH) - 438g
90mm Tele-Elmarit-M - 224g
135mm APO-Telyt-M - 454g

(sans caps, filters, optional hoods)

The only "document" I keep around is my home-made "Josef Albers" fields-of-view diagram.

I don't retain spreadsheets, except when I forget to delete them. I always make a spreadsheet of comparisons when I am considering a new lens, camera, laptop, external hard drive, binoculars, mobile phone, backpack, hiking boots, bean-to-cup coffee machine, holiday AirBnB, bicycle...........

I didn't, but I have done for film prices and sources, in different quantities (single rolls, multi-roll packs, 100' rolls)!

And for cost of setting up C41 processing at home vs commercial processing.

This sounds very useful!   I did something similar but not at the spreadsheet phase (yet).  There's a machine I had my eye on from UK but the cost doubles by the time I could get it shipped here so might have to rethink that

Hahah . Ah yes, a scale-breaking 685.5g "apparently" 

Just for interest's sake, Graham, I've just re-weighed my 90 S-C Summicron v3 on a set of digi-scales. These scales are only accurate to the nearest gram so no decimal points I'm sorry to say. It weighs-in at 686g so pretty much exactly the same as your own example.

To put this 'mass' into perspective my usual trio of 'carry-about' lenses - a 28 Elmarit ASPH v1; a v2 ('74) 35mm Summilux and a 50mm Summicron v4 - come in at a positively anorexic 561g for all three combined(!) their respective weights being 178g, 186g and 197g.

Admittedly the 90 S-C has a bult-in lenshood whereas the others were 'un-hooded' for the purpose of the experiment but even so; it is definitely on the 'Big Boned' side. It is, however, a beautiful performer and with looks to match.

I was looking at the Cinestill device, which looks like the cheapest option, and very practical. But I have to balance the costs of chemicals and the quantity of colour or XP2 films that I would want to process at a time, and the extra storage space I would have to find.

The 90:2 v3 is indeed fantastic .. I bought it on impulse (and largely on your recommendation) when I came across one in an in-person store rather than online.  Really beautiful lens. 

Definitely not for travel though is it .  I'm still keeping my eye out for the 'perfect 90' for that 🤔

I think that's what I'm going to do.  The machines I was looking at are the type where the paterson tank and other chemicals sit in holders in an electronic unit, and are presumably being kept at the right temperature through the process.  I can't recall the name but looked great and recommended here on the forum. But of course to get down here, the shipping costs as much as the unit (which wasn't cheap either).

I still may consider it for convenience, but will start with the Cinestill (or a similar generic cooking device) and see how I get on with colour developing.

I never want to own enough gear/lenses to warrant a spreadsheet, especially once the purchase has been made.  I pay attention to size and weight of SL lenses, but having owned DSLR, medium and large format film systems in the distant past, I’ve always considered my M system as the tiny sibling,  fully portable. Never more than 3 to 5 M lenses for my total kit (using one or two max for a shoot), typically Summicron or Summilux.  I couldn’t name the current weights, nor do I care; each is fine enough or I wouldn’t have bought them after handling. But no added weight or bulk from silly things like an EVF accessory for my M bodies… RF only.

First-off I'm happy relieved to read that you like the Summicron; otherwise I'd suffer from guilt-pangs for the rest of time............

Always bearing in mind that there is no 'perfect' lens; I've said it before but if I could only keep one of my 90mm M lenses it would be the Summarit.

Time for a few more weights and measures...

The Summarit is sharper at wider apertures than either of the Summicrons or the '74-'90 f2.8 Tele-Elmarit 'Thin' and handles beautifully. It has that half-stop speed advantage over the T-E yet is almost exactly the same length (69mm / 70mm) when these lenses are both sporting their hoods (reversed for carrying) and caps. The T-E weighs 115g less than the Summarit (225g / 340g) but the latter is still 145g lighter than the Black-Chrome finish Summicron (485g). The Summicron is also slightly longer than the others (82mm).

At wide apertures the rendering of the Summarit - as might be expected - is definitely more 'modern' than any of the others but once stopped-down to f5.6 there's really no appreciable difference in 'real-world' shooting (IMO). Mine happens to be the earlier "f2.5" verision which has a min-focus of 1m instead of the 0.9m of the later f2.4. For the sort of stuff I use a 90 for this 10cm difference has never once even remotely been an issue.

Incidentally - and as has been widely discussed elsewhere over the years - the f2.5 was, according to Erwin Puts, really an f2.4.

I've read this whole thread and can only come to one conclusion:

You guys are nuts 😁

Reaching for the kitchen scales just now I was surprised to be accused by Mrs C as being "the only person in the world who keeps a spreadsheet of the weights of their lenses"

I assured her this is very unlikely to be the case.

Anyone else ? 



 

 

Some years ago, fellow Forum member Jerzy and I started a joint (should really be giant) spreadsheet on the humble 50mm/5cm Elmar to determine how many variants actually existed. Von Hasbroeck had listed 25 variants, but, of course, we found many more, particularly after consulting the book by von Einem on Model I As with Elmar. Among the things we did were measuring the physical length of the barrel and also checking the focal length group for the ones which we actually had in our collections. This is the top of the sheet for the interchangeable examples (there was another page for fixed lenses) and there were 300 rows, indicating 300 example lenses, on this page alone. The one thing we did not do was to actually weigh the lenses. Eventually, Jerzy said that he did not have the time to go on with this and I was glad, as neither did I!

Yes we are, but we have loads of fun collecting and assembling obscure information that is only of interest to ourselves. We can walk around safe and secure in the knowledge that no one else knows what we know, nor do they care about that, so we are not harming anyone 😆

Hopefully it was clear that I was kidding.  I'm into Leica minutiae as much as the next nut, er, guy.
