Lenstip review of the Sigma A 105mm F1.4 HSM.
#48
Can we go back to the main subject
I'll try re-phrase my question that I have asked before.

1. What is the purpose of this lens? - there is nice art 85/1,4 and even beter 135/1,8 those 85 and 135 are not random numbers. They are comming mainly from yeras of portherts photography. Why do you need 105/1,4? what is special? - so far I know that low coma is nice for astro-photograpgy, and thats all about this lens

2. I still trying to figure out the purpose of the whole Sigma ART serias. Can somebody help here. For me thay lokk like
- you have the perfect lens but they are heavy and mainly fixed focal lenght. Who need this. Weding is done mainly with two zoom 24-75 and 70-200, travel and walakound amateurs are also zooms. For product photography you need Macro lens. Only for studio porthret soot is good fixed fast lens.

- How good is good enough - Take as example Canon 135/2.0 - It is lighter is cheaper it super reliable. Yes Sigma 135 shows better results at lab tests but how this translates is real life.
- what type of media will show the optical advantage of those lenses?

PS: about the S105 weight. Yesterday I was making portrait photo-shoot for about 30 min. Mainly with my canon 50d sigma150 macro and flash-EX580 that trigger the rest of lighting /if artificial light was needed/. I would say that this setup is already heavy after 15 min usage.
