Leicalook Posted September 15 Share #1 Posted September 15 Advertisement (gone after registration) Dear all, my researches lead to very different results. It seems that both extenders (1.4 and 2.0) fit - at least - Leica and Sigma. But which lenses? Maybe anybody here has some practical insights... (Sure that I have read at Leica. But that seems incomplete.) Thanks a lot in advance Stefan Link to post Share on other sites More sharing options...

Leicalook Posted September 15 Author Share #3 Posted September 15 Sigma writes regarding TC 1411. So wherever I look... I ask myself if I should buy Leica or Sigma - or are those 100% identical? If I buy 1411 (Leica or Sigma) does it work with 70-200 Leica, Sigma 105 seems too. Welcome, dear visitor!

BernardC Posted September 16 Share #7 Posted September 16 Advertisement (gone after registration) 23 hours ago, jaapv said: Nobody has been able to show an IQ difference between Sigma lenses and Leica clones.Both L mount and thus compatible Lots of people and site reported differences between Leica's 24-70 and the two versions of Sigma's "DN" 24-70, which have 3 different optical schemas. Several people here reported differences between the 100-400 lenses, but that may be down to testing and sample variation. However, the question is about lens compatibility with the two teleconverters, which seem to be optically the same for Sigma and Leica. Any compatibility differences would be in the firmware. I know that several people have confirmed that the 100-400 and 70-200 are compatible both ways. I don't recall if anyone has confirmed that the Sigma 60-600, 150-600, and 105 macro work with Leica's teleconverters. Presumably they should be, maybe someone here has those and can confirm.

jaapv Posted September 16 Share #8 Posted September 16 If they have different optical schemes they are not clones…The 100-400 , add placebo effect. Link to post Share on other sites More sharing options...
