Image quality and low light / speed capability superior. Great focal range from wide to short telephoto. I use mainly for landscape and travel. Great usability (buttons, placement, how it works with camera software). But, still heavy enough to be a burden to carry around everywhere if you are a minimalist. But, it’ll have to do if you want that range with low light and speed. The hood drives me nuts. Difficult to put on, always a hassle. Interior is like felt and collects all sorts of dust and pet hairs. Annoyed!
My alternative considerations, as someone who has back problems and doesn’t like to carry around a lot if stuff or bulky/heavy stuff include:
Replacing with Sony GM 16-35 2.8 when they make version 2, or my Tamron 17-28 2.8. My telephoto needs are already fullfilled with light weight hassle free Tamron 70-300 4.5-6.3, and I wouldn’t have to carry my Voigtlander 15mm. For landscape/travel/wildlife, I rarely use 35-65mm focal range (maybe 10-20% of time, and I feel like I could make those pics work if I didn’t have that focal range). However, being able to go from wide to short telephoto without changing lenses is valuable.
Replacing with Tamron 28-200 2.8-5.6, and I could leave my Tamron 70-300 4.5-6.3 home. Lose some speed and quality for convenience. Seems liberating. But in practice will cause difficulty in the longer end capturing dawn/dusk (low light), getting sharp photos without tripod, birds/wildlife frozen in action (high shutter that low aperture enables), etc.
Tamron 35-150 2-2.8 very interesting, but too heavy (~67% heavier).
Tamron 28-75 2.8 I hear is comparable. Lighter and much cheaper. I would need to test. I might miss the 24mm and possibly snappy autofocus Sony-Sony has.
Sigma 24-70 2.8. Heavier, albeit cheaper. Too heavy for me.
Good luck!
