Advertisement Posted March 10, 2023 Posted March 10, 2023 Hi pf4eva, Take a look here SL 100-400 f/5.6-6 Rebrand But Not the Same Lens. I'm sure you'll find what you were looking for!

I've seen others wanting a 21 SL as well. I have the WATE that I use for my SL2 and it performs very well and I pretty much set it at infinity when taking landscape/building shots. What's the benefit of a 21 SL when the 28 SL and 24-70 / 24-90 lens are available?   Quote Link to post Share on other sites More sharing options...

I love it for rooms, and social documentary. SO different from like, 35 or even 28. If I'm shooting a building I'll generally go my shifts because I'm a stickler for verticals. 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted March 10, 2023 Share #144 Â Posted March 10, 2023 No,that is the Lens Compendium. There is one for sale on Amazon right now. I meant the newer Leica Compendium. But no matter, in the part about Leica and optical design they both stress the importance of the mechanical construction for image quality.

I can never quite believe the difference.. Quote Link to post Share on other sites More sharing options...

Having a focus lock never occurred to me as a 'thing' until I heard here that the absence of one is very bad design. Not sure how you may not notice it, even if you hold the camera over the shoulder it extends every time, very annoying... This the only bad thing about this lens really, but that's an extremely bad design. Quote Link to post Share on other sites More sharing options...

Perhaps the difference is the weight of the elements? Brad Quote Link to post Share on other sites More sharing options...

cboy Posted March 10, 2023 Share #149  Posted March 10, 2023 It's obvious it's a tweaked rebrand. Leica users would be up in arms if it was a straight out copy. It's really up to individual if they want to shell out more for a tweaked sigma design, their money their happiness If however Leica straight out copied the z 70-200 2.8 Wr from Nikon I probably wouldnt mind as much 😆. They're better lenses to copy from. 2 Quote Link to post Share on other sites More sharing options...

But I would welcome any alternative at the long end to this It exists. The best lens Leica ever built. The APO-Telyt 280/4.0. R A stunning 500 LP/mm wide open, diffraction limited, reasonably compact and not too heavy, It smokes the 90-280. Put it on the APO-extender 1.4 R which does not perceptibly diminish IQ. 3 Quote Link to post Share on other sites More sharing options...

I can never quite believe the difference.. A prime example is the APO Summicron 50 M. The design had to stay on the shelf for eight years because it took that long to perfect the machining of the barrel to enable its full optical potential. 2 Quote Link to post Share on other sites More sharing options...

The best part is that it’s been great to see a good group of new lenses come out for the SL and the M series. Quote Link to post Share on other sites More sharing options...

jaapv Posted March 11, 2023 Share #156  Posted March 11, 2023 The APO Telyt 280 4.0 plus the APO extender 1.4 was my standard wildlife lens in the nineties until I replaced by the 105-280 R + 1.4x which was far more flexible and still very .very  good. Quote Link to post Share on other sites More sharing options...

It’s disappointing to have it with the 24-90. I experience it when I walk around with the camera/lens on my hip. Quote Link to post Share on other sites More sharing options...

I can control with a wide elastic over the zoom ring and body. It’s annoying but not worth sending it for repair. Quote Link to post Share on other sites More sharing options...
