Ivar B Posted February 2, 2019 Share #1 Posted February 2, 2019 Advertisement (gone after registration) Many have wanted for Leica to offer an extender for the SL - now I see that Panasonic will. I hope this will be fully compatible. Hopefully, the 1.4 could be a nice supplement to the 90-280 zoom. 2 Quote Link to post Share on other sites More sharing options...
Advertisement Posted February 2, 2019 Posted February 2, 2019 Hi Ivar B, Take a look here Panasonic Extender 1.4 and 2.0. I'm sure you'll find what you were looking for!

johnbuckley Posted February 2, 2019 Share #3 Posted February 2, 2019 In theory, it should be compatible, right? If it’s the same mount? Leica is showing, with the firmware update, a willingness to play well with others. Of course they could be planning their own, more expensive version...

I suspect that Leica will be glad to let Panasonic take the heat on that front! Teleconverters are almost always a big optical compromise, except when they are designed for one specific lens. Paying customers are more likely to accept these compromises if the converter says Panasonic on it. As far as compatibility is concerned, I expect that Panasonic will publish a list of compatible/recommended L-Mount lenses. That's almost always the case with converters. 1 Quote Link to post Share on other sites More sharing options...
darylgo Posted February 2, 2019 Share #5 Posted February 2, 2019 Teleconverter compromise vs. crop compromise, with a 47mp sensor and 189mp with sensor shift will a converter outperform a crop? Quote Link to post Share on other sites More sharing options...

Depends on subject, maybe crop works with static landscape, not so with moving bird or animal or human. 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted February 3, 2019 Share #7 Posted February 3, 2019 Advertisement (gone after registration) The APO extenders were not much of a compromise optically there was no significant quality loss. Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted February 3, 2019 Share #8 Posted February 3, 2019 But the R APO extenders were designed to work with Leica's 180 and 280 lenses at that time. Did they also work with the zooms? I don't expect a Panasonic design to be as successful with the latest L lenses, unless there has been some quiet collaboration between the companies. Let's hope that there has. Quote Link to post Share on other sites More sharing options...
didier Posted February 3, 2019 Share #9 Posted February 3, 2019 It would be great if a great APO extender could be used with the L 90-280 2 years ago I wrote to Solms to ask if they would come up with an extender, and the answer was without any hesitation : no. I hope things have changed. Be the extender Panasonic or Leica, I just hope it will work with the 90-280 and be up to the Leica standard !

PeterGA Posted February 3, 2019 Share #10 Posted February 3, 2019 90-280 on CL - would it be the same as a 50% crop on a 47MP sensor? I suspect so..... Welcome, dear visitor!

Let's hope that there has. I used them extensively with both the 105-280 and 80-200. No optical quality loss that was visible in the images. Even 1.4x and 2.0x stacked worked. 1 Quote Link to post Share on other sites More sharing options...

Perhaps also in this day and age some software optimization could at least partly correct whatever optical aberrations might be present. Very good is most of the time also good enough - a small quality loss may remain unnoticed. Quote Link to post Share on other sites More sharing options...
Bohns Posted February 4, 2019 Share #13 Posted February 4, 2019 (edited) I personnally wait for those extenders with some enthusiastic impatience, and hope not to be disapointed. But not only optical quality will be of importance when mounted on 90-280; I expect limited or zero impact on SL AF performance, considering that - although speed will be limited to f/5.6 or f/8 - the AF techno is based on liveview. Pending both those expectations are filled, spend will be a no brainer, at least for the 2x, and maybe as well the 1.4x. Then, my remaining Canon (very) heavy gear for wildlife will be available for purchase. 😉 Edited February 4, 2019 by Bohns Quote Link to post Share on other sites More sharing options...

But I will likely wait until Sigma comes up with their long-lens offering(s), hopefully a 500mm f4 or thereabout. I am less optimistic when it comes to AF with the extenders; the 1.4x and 2.0x reduces the light to the sensor and consequently, I belive, will tend to reduce the speed and/or precision of the AF. Time will tell; but it is nevertheless good to finally have options beyond 280mm... Quote Link to post Share on other sites More sharing options...
Bohns Posted February 4, 2019 Share #15 Posted February 4, 2019 (edited) Light has nothing to do for liveview AF. Contrast does. And slower speed does not necessarily mean lower contrast. wait and see... Edited February 4, 2019 by Bohns Quote Link to post Share on other sites More sharing options...

My comment was based on the fact that the SL's AF works gradually poorer in low light, but I am glad to be proven wrong. Quote Link to post Share on other sites More sharing options...
caissa Posted February 5, 2019 Share #17 Posted February 5, 2019 (edited) It could also be interesting to use the extenders with the primes. 1.4x with the Summicron SL 90 could give something close to 2.8/135 (actually 126). I’m maybe old-fashioned, but I love the classic 135. This would help to shorten the waiting time until Leica finally offers a native 135 - maybe never ... 🌝🐞 I love the quality of the SL 90-280, but since I have the primes I sometimes would prefer also a light tele lens. For the SL 90-280 I would prefer a 1.7x extender. (Resulting in 153-476). Edited February 5, 2019 by caissa 2 Quote Link to post Share on other sites More sharing options...

If it is Canon level, I will switch. I also hope for a L 100-400. 1 Quote Link to post Share on other sites More sharing options...

I would imagine Sigma Art/Sport/Contemporary lenses fitted with L flange will be almost the same, including optical formula, as any other existing DSLR/Mirrorless mount lens except for the flange and firmware. There may be small difference in weight and barrel length - probably heavier and longer. Quote Link to post Share on other sites More sharing options...
