14 Sigma Lenses for 2019 in native L Mount

If I don't start seeing some evidence that there would be hope for adaptation or use of the new Sigma 60-600 on the S1 I might have to cancel the order. It is a huge part of the reason I'd consider the S1. The Canon R already accepts it well.

That is awesome, I wonder if Sigma is planning to release some of their zooms as well. I would love to switch to Lumix S1r, but I need my beloved 12-24 Art. Once they do that I am in!

I believe that there will be SA and EF adapters to L mount made by Sigma which will be the identical size, similar combined weight, and most likely identical functionality to remounted new lenses previously made for other mount systems.

The only practical difference would be that one might be a universal adapter for all lenses made for that particular lens mount and the other would be an “adapter” built into each remounted lens.

Think it out - it is not rocket science. If I was designing an electronic lens suitable for many different host mount systems I would make my interface to drive my own lenses to my own standards terminating in a known set of contacts. Then for each mount system I would assign their individually translated protocols (as known) to the common Sigma lens protocols.

The process must be almost identical whether it inside a purpose made and attached “new end” or inside a mountable adapter made for the same purpose.

Indeed it is not rocket science, yet your conclusion is not right. Sigma have clearly stated that an adapted lens will not perform as responsively as the same lens with an inbuilt native mount. The reason is protocol translations, as you have rightly mentioned.

So, an L-Mount Sigma 85 Art prime (for example) will out-perform an EF-Mount Sigma 85 Art prime plus an EF-to-L adapter. With any luck, this will only occasionally be noticeable.

Plus, the double flange tolerance on the adapted setup will slightly soften the edges. This would only occasionally be visible.

If Sigma would deliberately cripple their adapter then it must be entirely on their own head as third party adapters are bound to emerge soon enough.

The main difference would be that a Sigma lens made for (say) EF would have already translated the Sigma lens common driving protocols to EF mount protocols and the adapter would have to further translate these to the L-mount protocols. Whereas the new L-mount lens end would simply do one direct translation Sigma internal -> L-Mount. Unless they were “lazy” and simply took the internal EF translated connectors and re-translated them into L-Mount in the same way as the adapter might do.

Whatever method adopted the speed delay in the translation process who be hard to measure. Maybe some of the finesse might get “lost in the translation” but for all practical purposes I think that adapted Sigma EF to L mount could hardly seem different in any practical sense from the same Sigma lens remounted as L-Mount.

Yes, it will seem similar, but if you want the best the system has to offer, native L-Mount lenses are the only way to get it.

An Inconvenient Truth, perhaps.

So Sigma has promised EF to L mount adapter for their lenses. They will also offer lens conversion service for existing lenses and finally, I would be surprised if they didn't make the 60-600mm in L mount natively since they made all their DSLR lenses for their own SA mount until they now change to L-mount for their cameras.

Ahh thank you. You've restored my confidence in this decision. Indeed if Sigma has it on their soon to be plan I'm thrilled. By the fall I plan on getting a 60-600 so that may do the trick.

It sounds like they are going to "bake in an adapter" to their existing DSLR-designed lenses like they did with the Sony FE Native mounts. It's not the ideal solution as far as size is concerned, but it works very well and will help launch the L-Mount system on a good, solid footing.

It will be OK for zooms (as they are already big enough that the added length of the adapter won't make such a big difference). For primes, however, I feel that they will become unduly longer than they need to be.

According to Sigma, a totally mirrorless-based design could only make primes shorter for focal lengths below 35mm.

So, you're not missing out on much with the approach they are taking.

I mean to be fair if you look at Sony FE releases and you do see quite a few that are actually larger than some DSLR designs.

The problem I's say that its "some DSLR designs" not all, Sigma's DSLR recent art primes on the other hand already tend to be quite large/long with the added "baked in adapter" are generally longer than native lenses even above 35mm.

It will be an interesting year. I look forward to seeing the lenses designed for mounts with a short flange distance. I wonder if any will be macro designs. I'm hoping to see a small and compact, full-frame 50mm f2 or f1.8 Contemporary that's as good as the 56mm f1.4 Contemporary. Imagine THAT?!?

And not one of those lenses is of interest to me. I'm ONLY interested in being able to add the new Sigma 60-600 which so far is only available in Sigma, Canon and Nikon mounts. A competent (NOT what's out there currently) EF-L adapter would have to come out by someone that can or will market it at or under $300 or I'm not going to be a happy camper. If Sigma would add the 60-600 as a "L" mount that would be perfection. Or at least their own adapter from Sigma to L.

Fear not.

11 Full Frame, 3 APS-C (the last 3 in the above list)

The 11 full frame models above just got announced. But their identities are not news for readers of this thread!

His actual words, "We'll make the L-mount version of those lenses next year. And also, we will release some more lenses designed for the short flange. So that means from an early stage, users of this new L-mount system will have a wide variety of lenses available."

A wide variety of outstanding quality, leading-edge IQ lenses.

And we already know their prices. And we know from experience the Nikon and Canon equivalents, if ever made, will be 50-100% more expensive, and no better IQ, at best.

Nikon show 9 lenses by end 2019. Canon show 4, of which 2 are $2,300+, and let's say they add 4 more in 2019 for a total of 8.

And we have to add Panasonic's L Mount lenses, which surely will number 3 or 4 for 2019, minimum.

And at the top end price-wise we already have Leica's 12 compatible lenses (6 full frame at top of this list, and 6 APS-C):

1. Leica Super-Vario-Elmar-SL 16-35mm F3.5-4.5 ASPH
2. Leica Vario-Elmarit-SL 24-90mm F2.8-4 ASPH
3. Leica Summilux-SL 50mm F1.4 ASPH
4. Leica APO-Summicron-SL 75mm F2 ASPH
5. Leica APO-Summicron-SL 90mm F2 ASPH
6. Leica APO-Vario-Elmarit-SL 90-280 mm F2.8–4
7. Leica Vario-Elmar-T 18-56mm f/3.5-5.6
8. Leica Elmarit-TL 18mm F2.8 ASPH
9. Leica Summicron-T 23mm f/2 ASPH
10. Leica Summilux-TL 35mm F1.4 ASPH
11. Leica APO-Vario-Elmar-T 55-135mm F3.5-4.5
12. Leica APO-Macro-Elmarit-TL 60mm f2.8 ASPH

I'm seeing about 30 L-Mount lenses available without adapters by the end of 2019, comprising 21 full frame and 9 APS-C. Plus Sigma's hint at some short flange native designs in the above quote.

Who da man?

Additionally, Sigma announced today that the SA/EF-to-L adapter will suit 12 full frame Sigma lenses and 6 APS-C Sigma lenses.

Whether it will work with Canon's own-brand EF lenses is not Sigma's problem (of course) and up to the user to try at one's own risk.

One disappointment is that the AF will only work with Single-AF mode, so, for the 150-600mm tele lenses in particular, that is a blow.

My most significant concern at this time regarding my investment in the S1 with it's L mount is while the 24-105 is no question the first lens I'll have........the 2nd one I've planned on getting is the new Sigma 60-600 Sport lens. It worries me that Sigma won't make a L mount version of it.......and if they don't the performance of it will be greatly compromised......which I won't like one bit! The Canon mount for that lens works perfectly on for example the "R". Which Canon will likely do a pro version of at the end of this year.

So as good as the S1 may (and I hope) is....it will cause me to perhaps have to sell it off if it doesn't accept the 60-600 easily and most perfectly.. I guess some time will tell.....and of course I'm not even 100% certain I'll keep the S1 after a road test when it's released. Providing the higher ISO's are like what I'm seeing examples of, AND it doesn't have that annoying pulsing focus in the viewfinder I'll keep it. Otherwise it will go back. Guess less then 6 weeks from now I'll find out.

I believe it's because there are some L-mount Leica cameras that have aps-c sensors. I might be wrong though.

Sigma values the people who spend the kind of money L-cameras currently cost. They were nowhere near this enamoured with the m4/3ds market (despite it being far larger) which was/is considered much lower-tier and thus produced few lenses for it.

Sigma are on record saying that the 4/3 m4/3 system has such a good lens system already that they don't see opportunities.

L Mount is a completely different calculation for Sigma, because they have adopted it as their "own camera" lens mount, so every new Sigma lens will be offered in L Mount, plus many of the existing Global Vision lenses.

If Sigma announces plans for a 100-400 or a 60-600 length range true "L" mount by next spring I may jump in the S1R waters. I need to see evidence of a longer lens, not just the plethora of wide's and mid zooms before I commit to a mount. It is rumored they will, but a rumor isn't going to do it for me. I need PROOF.
