although the price is worth every penny paid. perfect images and with absurd angles. As an amateur photographer Im having a lot of fun taking pictures with my 5D Mark IV and this lens. really a little heavy but nothing too much.

In my experience with this lens, the image quality is excellent. There is barrel distortion at the widest angles but this is easily correctable in post-processing. Also, this is less noticeable in many scenic photos (with no horizon line). My one complaint is that the stated item weight of 1.5 lbs appears to be misleading. See my photo. On my admittedly not high end kitchen scale the weight with the plastic caps is close to 3 pounds.

This is my third A-series Sigma, and my second to experience inconsistent AF acquisition (24-35 f2 is the other). Not that this affects day-to-day use. This is not a lens for sports or other action subjects. For consistent AF, I've learned to defocus the lens manually and let it snap into focus with a double touch to the shutter release. Do that, and it will yield perfect focus; however, if the lens is near its focal point at the time of release, it fails to make micro adjustments and results in a throwaway image file. For optical performance, I recommend dxomark's lens database. Access the sharpness field maps. You will discover that this lens is sharpest at 12mm@f5.6. At the other end of the zoom range, 24mm has to be stopped down to at least f8 and preferably f11 to be usable. Live with these limitations and it's a fine performer, albeit an expensive way to gain a few millimeters at the wide end.

Took lens with me to the Netherlands and played around with it there. f4 isn't a hindrance since you'll be shooting landscapes and architecture anyways. Minimal distortion (you'll still have the normal distortion if subjects are too far to the sides of the lens) and vignetting. Both can be fixed in post editing. It is a big lens. And heavy. But if you're shooting wide, you kinda get use to that. Haven't tried filters on it since Sigma doesn't make any for this lens. You'll have to go to a 3rd party and because of the lens size, it will cost you. The lens has low flaring, and no chromatic aberration that I could make out. All my shots were taken with a Canon 5D mark IV. Yes, the lens is expensive. But you are buying a sharp, fast, profession lens for a lot less than the other lenses in the category.
