I am a big fan of a 3 lens limitation for my camera bag. Always FFL. But I always end up with using 1 lens only in 90% of the time and the two others stay in the bag until specific situations occur, which I can not handle with that one lens.
With MFT it was always the Leica 15/1.7 (=30mm) in 90% of the time, the Lumix 42,5/1.7 (=85mm) in around 8% of the time and the Leica 25/1.4 (=50mm) for the 2% left. I used other lenses only in special situations when needed and when I knew this in advance.
Plus always Ricoh GR and later also GR3x.
This distribution was always different with fullframe. I can not explain why. With Nikon F & Z, and Sony A mount, I used more 50mm and 85mm. With Nikon APS-C and Fuji the equivalent of 50mm fullframe. Really weired...
But when I started with L-Mount, due to the lack of my preferred focal ranges as small FFL, I experimented more with zooms. Without success. As soon as Sigma introduced the small i-series with aperture rings, I was hooked again and my zooms collected dust (except for sports photography).
As soon as the Sigma 50/2.0 DG DN came out, this was my most used lens with around 90% of the time outside of sports photography (due to the lack of a 28mm FFL) and the Sigma 90/2.8 DG DN was used around 10% of the cases.
With the introduction of the Leica Q3 43 this changed again. It replaced all my MFT use cases and most of my use cases for the Sigma 50mm DG DN.
In 2025 I used L-Mount only for sports photography (70-200/2.8) & special use cases, i.e. family events, birthdays etc. with lenses like Sigma 35/1.4, 85/1.4, 135/1.8 etc. But these events are rare nowadays and do not really count for the statistics anymore.
Therefore for 2025 I have to admit that I used in my "3 lens kit" :
1. Leica Q3 43 (around 80%, for travel)
2. Ricoh GR3 (28mm) & GR3x (40mm) (around 10%, for travel)
3. Sigma 70-200/2.8 Sports DG DN (around 8%, sports only)
Sport photography will be even less in 2026 & 2027. Kids are almost too old now. Sad...
I would love to see a Sigma 28mm, so that I am more motivated to take my S1R2 with the 28mm and 50mm for travel with me. Or a new Sigma 40/2.0 with image quality like the 50/2.0. I really love the 40mm focal length a lot and I want to have an alternative with EVF to the Leica Q3 43
