There are no optical adjustments in the Sigma 35mm f/1.4 Art lens that we can find. There’s another thing that needs to be discussed at some length. But if I want to carry several primes in a convenient size and at a convenient expense, the Sigma is a superb choice and I expect it will hold up very well. If I was going to subject my lens to harsh conditions and use, the Canon looks like the way to go if you can afford it. The Canon is weather resistant, twice the price, and twice the weight, roughly. Many people are going to compare this lens to the Canon 35mm f/1.4 teardown we did and say that’s why they chose the Canon. There’s nothing in this teardown that looked like a weak point. Little touches like pegs to make sure a part is inserted in the proper rotation and shields over critical parts didn’t add much expense or weight, but show care was taken in the design. Instead, I’d characterize the construction of the Sigma as very efficient and carefully laid out. There’s a solid metal core with other parts all connecting directly to that core. There isn’t the amazing heavy-duty construction of the Canon 35mm f/1.4. We’ve seen how Sigma has remade themselves as a company making only superb optics at very reasonable prices in the last few years. Conclusionsįor the most part, there weren’t many surprises in this teardown. And just like every time, someone is going to comment online that we killed a lens to do a teardown. Of course, the lens is reassembled, retested, and working fine.
