Sigma 18 35Mm F1 8 Lens

[Glass] Fits like a glove on the Sigma 18-35mm f1.8 lens. No complains so far.

[49 mm (Front)] Nothing against this lens at all but for $ more you can get the Sigma 18-35 F1.8 .And we all know thats why none of the Pentax lens that are between 18mm and 40mm prime lens are being sold.People know that the Sigma 18-35 f1.8 is like having a 18mm,19mm,20mm all the way up to 35mm prime lens all in one lens .And its sharper than the pentax 35mm 2.8 prime lens. Pentax is going to have to reduce the price of this lens. It makes no sense to pay this kind of money for one lens when you get better pictures from the Sigma lens and have 18 lens build into one lens that better and they are all f1.8 .

[21mm] Great lens. Really sharp and much better bokeh than the Sigma 18-35mm lens I have been using. The clickless aperture and focus ring have LOTS of throw, so be aware of that - I personally wanted this so it's a plus for me. Got a courtesy call from B&H to confrim the purchase, despatched same day and arrived 2 days later from US to UK so extremely happy with service.

[Manual] I'm using a fairly heavy combo of a Canon C-300 with a Sigma 18-35mm lens and a Glidegear TMP - 750 teleprompter. That's just under 20 lbs. The Manfrotto head I was using tended to tilt forward or backward with the weight when locked down. The Smith Victor doesn't. I also like the dual control arms and the included quick-release plate. I'm using it in a fixed position but it does seem to pan smoothly.

[1/4"-20 Female] I finally ordered the Metabones Speed Booster as well as the Sigma 18-35mm lens for my Blackmagic Pocket Cinema Camera. I'm very satisfied so far. The Speed Booster works as advertised. It is very well built. There is a ring to control lens aperture. Also you can mount your tripod adapter so that the camera does not have to support the weight of heavy lenses. Optical quality is excellent.

[Black / Brown] I recently purchased the Pro version of this software when it was on sale at B&H and not expecting that it would do much for my “S” lenses, I was astonished at the results.  There isn’t much difference between +/- 2 on the graphs for the “S” lenses compared to a greater difference on “F” mount or my Sigma lenses.  All my lenses required some form of adjustment but it seems my sharpest lens is the Sigma 18-35mm 1.8 - still trying to understand that one.  My 2nd sharpest is the 24-70mm f2.8 yet the best performing over all. 24-70mm f4 S            -1 at 24mm 24-70mm f2.8 S        +1 at 24mm, +3 at 70mm 50mm f1.8 S.             +2 Sigma 18-35mm       +3 at 20mm 70-300mm f5.6.        +3 at 70mm 14-30mm f4 S.           +1 at 24mm The resulting graphs showed very little change between +2 and -2 for all the S lenses yet the program determined the most optimal setting for each lens tested. Overall, I find this software to be very beneficial for my Z6 camera.

[95 mm] I use it on a 114mm SmallRig Matte Box with a Cinematics Sigma 18-35mm T2 and it fits, it does protrude quite a bit from the matte box (into the body of the lens) but still it ties well, feels secure.

[Glass] Needed a good ND for my Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF that would not break the bank. This was it.

[6.43 lb] Anyone who uses a lot of cine glass knows that the 18-35mm Sigma Cine is legendary for into film makers. Please ignore the other 2 star review as this person clearly doesn't understand the value of lenses. The lack of LDS makes this lens actually "affordable", and speaking of which, is considered CHEAP for the quality of the optics and build. A lot of people are ordering entire era of primes and zooms for RED cameras (ourselves included) for a reason. Sigma Cine lenses are arguably the best value for the superb quality in the industry right now.

[0.6 lb] I use this for my YT channel HOT BRASS AND BULLETS . With my GH5 and the Sigma 18 35mm art lens which is heavy . it's easy to use and powerful . Camera can come off and on with know adjustment once you set it up.
