when lighting condition is poor u will know what thes different f1.4 vs f1.8 Dun need a noob like me to tell u right? Anyway i wish their next lens would be 35mm f1.4.. perhaps that would be a fair comparision against the sigma 30mm.![]()
So losing that 2/3 stop advantage is the downgrade?
Dun need a noob to tell me that.
But what if at f/2 onwards the Nikon 35mm f/1.8 is superior to the Sigma 30mm f/1.4 all the way to f/16?
And what if at f/1.8 the lens is also superior to the Sigma at f/1.4? Cham liao!
You can give me a f/1 lens and if that lens is full of distortion, CA, not sharp, turn a green dress yellow, I will go for a f/3.5 lens that is well corrected, sharp and give faithful colour reproduction.
Bottom line - shot at controlled conditions and review the shots then we know if it is a downgrade. f/1.4 is just a number until shots fired, kills counted, prisoners taken.
And don't forget, even similar performance between the 2 lenses is an advantage to the 35mm f/1.8 due to price difference, unless you die die must shot at f/1.4 then nothing to say lah.
Having said that, I fully expect the Sigma to have an edge over the Nikon, how much of an edge is the question. After all, the Sigma is a statement product, to show that it is good and superior to the original brand names, and the Nikon is a made-for-mass market product, so they cut cost in many areas. Even the Sigma 50mm f/1.4 is said to be superior to the Nikon version.
So relax, don't need to get excited, it is probably true that going to the f/1.8 lens is a downgrade, but what I want to say is that don't say that until it is proven photographically.
