p.2 #1Zeiss Milvus vital stats, compared with Otus, Classic, and C/Y
I guess these Milvus lenses got larger and heavier than their ZE/ZF versions due to the newly designed, curving barrel and hoods. If that's the case, then I think it was an odd choice to add weight to a lens just to make it look more modern. But who knows, maybe Zeiss is counting on some buyers to "wear" these lenses as a fashion statement.

The new pair are spin-offs of the Otus development program, almost certainly; but...920 grams and 1280 grams? No one will be walking around shooting street with these. Lee, they wanted to bring new lenses with significantly better IQ to the pro portrait market. And they are better at the right price, but seem likely to spend most time on a heavy tripod.
Dear god what the...one of the main reason I like my MF lenses is the weight advantage over AF glass. No way I would invest in these unless I was exclusively a studio photographer, but even with them the majority stop down the lens to f5.6/f8.

Oh, by the way Jim, great work with the chart, a very interesting resource. One nitpick, if it were me I'd omit the C/Y 100/2; since it wasn't a macro IMHO it was a completely different lens which had no successor rather than an ancestor to the 100MP and Milvus 100M.

The old 100mm f/2 ZE is 699g without caps or hood, and the hood is 64g, for a total of 763g without caps. With the original caps it's 790g. (I just weighed mine on kitchen scales, because the value in the table looked wrong.)
Assuming the figure for the Milvus version includes the hood, it's still 50g heavier.

If the new weights listed in the data sheets include the hood and caps (the old data sheets for the ZE/ZF did not), then that explains almost all the weight difference of the the rehoused lenses. We are then talking just 20 to 30 grams more per lens and that could be the seals for weather sealing and a better front cap (which is worth a little extra weight, IMO). I suppose once people get the lenses in hand we will know if the reported weight includes the hood and caps or not. This should be easy to check. Possibly consistent with this interpretation is that the old data sheets for the ZE/ZF did not include the hood in the top pictures of the lens, whereas the new data sheets for the Milvus lenses do include the hood in the top pictures of the lens.

Weights in the 'classic' ZE and C/Y data sheets do not include hoods or caps, and so I assume it's the same for the Milvus data sheets.
I just verified this by weighing my Distagon 18/3.5 ZE and Makro-Planar 50/2 lenses. Their weights on my pelouze PE10 micro scale are exactly the same as in the Zeiss ZE data sheets; 510g and 570g, without hoods & caps.
I just sent an email to a contact at Zeiss.de, to ask if the Milvus data sheet weights include hoods and/or caps, or not. I'll post the reply as soon as it comes in.

While checking the weights of my lenses with the Zeiss data sheets, I noticed a discrepancy between the Lens$db weights and the Zeiss data sheet weights. for three lenses. Also, some of the lens geometries were off.
Turns out, I used B&H spec sheet data for the ZE lenses when they were added to Lens$db. As shown in the attached table of lens weights, the B&H weights were (and still are) wrong for some Classic ZE lenses. Also, some of the B&H spec sheet dimensions are wrong (in comparison with Zeiss), and in at least a few cases, ZF dimensions are stated for ZE lenses.
I have all of the ZE classic data sheets, and so I'll check them all and change the Lens$db database where appropriate. Then, I'll update the table at the top of this thread.
I can't explain the difference between melcat's 100/2 MP ZE weight of 699g, the Lens$db weight of 680g, because the Zeiss data sheet also says 680g.

Only the new 50mm/1.4 and 85mm/1.4 are substantially different optically from the ZE/ZF designs. The Milvus 50mm/1.4 and 85mm/1.4 are substantially improved, and much more closely resemble the Otus lenses in optical layout and MTF than they do the ZE/ZF versions, at least on paper. I wonder if Zeiss has worked on controlling secondary longitudinal color errors compared to the original 100 MP. That's the one thing that keeps me from fully loving that lens.

Thanks for checking Jim. That is much appreciated. I am still a bit baffled by why the weights have gone up about 130g per lens. I like that the lenses are weather sealed. I like the new hood design. But why with the same glass would the weight increase so much? Perhaps when Lens Rentals does a tear down something might make sense.

I really am not a person who minds heavy gear at all so the added weight doesn't bother me that much (except insofar as idle curiosity about why it's there), except for one thing: where's the tripod foot? Several of these have gotten to the point that they need them.

That and now since they have the newly designed Otus casings. You can expect impact damage reports to go up 100 fold.

I don't think so. They just changed the lens housing. I'd also love to see an Otus macro lens.
