Ivar B Posted June 23, 2020 Share #21 Posted June 23, 2020 Advertisement (gone after registration) There is a review on youtube. Almost as good optically as the same lens from Sony but weaker autofocus. 3 1 Link to post Share on other sites More sharing options...
Advertisement Posted June 23, 2020 Posted June 23, 2020 Hi Ivar B, Take a look here Long L Mount telephoto. I'm sure you'll find what you were looking for!
jaapv Posted June 28, 2020 Share #22 Posted June 28, 2020 Now I’m glad I ordered the lens Link to post Share on other sites More sharing options...

Keep in mind that he's testing the Sigma on a Sony. I find it odd that he tests for resolution in the near/macro range, using bank notes. Super-zoom lenses are probably optimized for a longer range. That's always a limitation though. Long-range resolution tests often tell you more about the weather, and the tripod, than they do about the lens. I remember a Zeiss article that said that you can only reach the full potential of a lens on a still day, in the few minutes after sunrise. Link to post Share on other sites More sharing options...

Super-zoom lenses are probably optimized for a longer range. The idea that lenses are only optimized for one particular subject distance range is a bit old-fashioned. Once a lens is made with a variable optical formula (e.g. zooms, internal focusing, and/or floating elements), it can be optimized for any and all focus ranges. Not all are - but the potential is present. E.G. the 75 APO-Summicron-M, which has pretty much identical (excellent) resolution from infinity to 0.7m (1:7 magnification). Or (speaking of old-fashioned) the original 24mm f/2.8 Nikkor-N from 1967, which was the first general-use prime lens for 35mm photography to use floating elements (what Nippon Kogaku called CRC - close-range-correction) - for just that reason. Now of course a zoom may be optimized for different focal lengths (better resolution at 100mm than 400mm, or vice-versa). But that is more a question of just how complicated, large, and expensive the manufacturer is willing to make it - not an optical necessity. 1 Link to post Share on other sites More sharing options...
jaapv Posted June 28, 2020 Share #25 Posted June 28, 2020 He does address the distance question - and comments on performance at various distances. But. as he notes, once one gets near infinity on long kenses distortion by air becomes a factor. 1 Link to post Share on other sites More sharing options...
Boojay Posted July 8, 2020 Share #26 Posted July 8, 2020 Wondering if anyone else had bad news on the 100-400 front. Just spoken with dealer who has my deposit, after speaking with Sigma July 10th date out of the window in UK - probably looking mid- August. 😒 Link to post Share on other sites More sharing options...
jaapv Posted July 8, 2020 Share #27 Posted July 8, 2020 Advertisement (gone after registration) Yesterday my dealer told me they were expecting the lens “ end of the week” Of course, they may have been unaware of new developments. 1 Link to post Share on other sites More sharing options...

tritentrue Posted July 9, 2020 Share #29 Posted July 9, 2020 The previous word I heard for these parts, specifically Singapore, was that the lens would be in stores by July 10. Now my favorite local store says end July/early August. I just sent a query to the local Sigma office, hoping for something more enlightening than an "f/32" response . . . 2 Link to post Share on other sites More sharing options...
bags27 Posted July 9, 2020 Share #30 Posted July 9, 2020 And here I just yesterday shipped off my 80-200 plus extender to a Leica store in exchange for an M lens. I guess that's the end of my birding this summer. 🙂 1 Link to post Share on other sites More sharing options...
tritentrue Posted July 13, 2020 Share #31 Posted July 13, 2020 Update: I just received a message from my favorite local shop that the Sigma 100-400mm L-mount arrived this afternoon. I'll pick up my copy tomorrow morning. Also I noticed on a USA website that the seller expects stock on the 15th, so hopefully the lens is on its way to other places as well. 😀 2 1 Link to post Share on other sites More sharing options...

Just checked with my supplier UK - still thinking mid August. Edited July 13, 2020 by Boojay Addition 1 Link to post Share on other sites More sharing options...

jaapv Posted July 13, 2020 Share #39 Posted July 13, 2020 Well, I expect that the price is based on high sales expectations. The lens is not only interesting for CL/TL owners, it is an affordable and compact alternative to Leica’ s 90-280 for SL2 owners and they offer it in different mounts. I still cannot imagine what Leica was thinking, leaving this gap in their system. They could have sold plenty at double the price or more. 1 1 Link to post Share on other sites More sharing options...
