While the motor wasn't as quiet as those on NIkon lenses, it wasn't loud. At 82 mm, the filters are necessary but rather pricy.
As with the others, this one was inexpensive (especially when compared to Nikon's), well built (lots of metal), & 2.8 throughout.
SIGMA 24 70 2.8 DG EX FULL
If ever Pentax/Samsung release a full frame camera, I think I got the wide angle covered then!Ģ0+ year Nikon user - 3rd Sigma EX lens purchased. With this lens, I am now thinking of getting these other EX lenses: Others claim that the auto-focus is noisy, and I feel that it's overly exaggerated. The Macro function and the capability to focus to very close objects is a very good feature as well, and it works! Finding a filter was bit of a pain because it uses 82mm filters so take that into consideration.
I also like the finish of the lens overall. The Tamron is lighter, which can be a good or bad thing for you. The closest competitor to this lens would be the Tamron 28-75 which is a winner in its own right. I can heartily recommend this to anyone looking for a standard zoom lens moving up from the kit lens. I was able to purchase this for £220 from Onestop Digital and am very happy with it. I guess there's people out there that actually feel the extra cash paid for USM is worth the silence it provides. Maybe my copy has quieter than usual gearing, since the noise isn't distracting or a nuisance, even when looking through the viewfinder. Try listening from a 6 foot distance, with someone else prefocusing. One simple fact that is terribly overlooked is that when people evaluate the noise factor, they are most often looking through the viewfinder with the lens only inches from their ear, which is an unfair evaluation. It is extremely fast to focus, all the way from closest focus to infinity.Ī word about 'noisy' focus this lens is blamed for. It is not the HSM autofocus, it uses the 'screwdriver' focusing mechanism. My copy was bought used, in pristine condition. The 24-70mm f/2.8 EX DG DF is a truly amazing lens.
SIGMA 24 70 2.8 DG EX PROFESSIONAL
Third Sigma EX series lens I've purchased, also have the 20mmf/1.8 and 10-20mm f/3.5+, both are truly fine lenses in build, sharpness, color rendition.Įven with regular professional use, I have found the Sigma EX lenses as good as equivalent Nikkor lenses. Sigma could charge more for these EX lenses, considering their image and build quality. Not really cheap, but more affordable than inferior counterparts, especially OEM. No front or back focus issues, hits the target every time.Ĥ. Lens is not prone to hunting or AFC dancing, even in low light. Screw focus goes from closest to infinity very quickly. The flat finish is much easier to hang onto and control under these conditions. Some people don't like the flat matte finish, but it offers a more solid grip surface than a polished surface, especially when hands are cold, sweaty or when wearing gloves. The sharpness of this lens is truly amazing.Ģ. Many say this lens is noticeably sharper than the Canon L or Nikkor ED equivalents at any aperture. At f/8 to f/22, its almost ridiculous, reminds me of the finest Schneider optics on Hasselblad and 4x5 shot on a locked tripod. Incredibly sharp optics, at f/3.5 or above.
