It came without box or manual, but with caps and hood. Just got the Sigma 24-70 Friday evening (2 days ago), from KEH, who rated it EX+.

I won't recommend this lens to anyone who looking for pro quality F2.8 zoom lens.īuild quality, sharpness, color, easy focus If your body in AF mode and when you press AF button on the body rotates the focus ring may cause a damage if you are holding the focus ring. when in AF, focus ring rotates freely and affects nothing. Pull the focus ring for MF and push it back for AF. I liked its big focus ring and AF/MF switch operation. I don't use strap, but I installed the strap because I am worried of total weight. Handling, Autofocus: way too heavy to carry around if you use external flash and battery grip at same time. And also flare is a big issue.īokeh: good, colorful blurry background. But when stopped down to f4, it produces sharp images, CA almost gone. very soft and CA appears through the frame even at focus point. because it is soft for EX line up lens at f2.8. AF works fine, not Back and Front focus issue. I should mention that a copy I had was bad copy, that was dropped previously and zoom ring was stiff. Sharpness: 8 Aberrations: 7 Bokeh: 8 Handling: 6 Value: 7 Camera Used: K5iis It would be interesting to try it on FF digi camera. Other parts ale nice and stiff.Īlso the reversed design, where lens extends towards to 24mm and retracts towards the 70mm end, is a bit strange.īut keeping in mind how old this lens is and how cheap it was for an F2.8 autofocus zoom, it delivers a lot.

Lens zoom creep is jus slight in part of the range, but my lens is used. Lens is quite big and heavy, built on a high quality standards.

Thanks to 9 aperture blades the bokeh is pleasant and nicely circular.ĪF is fast and +/- accurate as camera body allows. It seems to be sharpest around 35-50mm range. F2.8 is quite usable, but lacks contrast and detail a bit when compared to modern Sigma 17-50/2.8. I bought this lens for a good price in used condition. Sharpness: 8 Aberrations: 8 Bokeh: 9 Handling: 9 Value: 9 Camera Used: K3, K5, K20D, MZ-10 Autofocus: 8 New Or Used: New Of course I didn't expect it to perform as well as the DFA 24-70, but I also didn't expect the corners to be THAT bad at the important 24mm setting.įF lens, build quality, fast focusing, aperture ring, F2.8 But as this is supposed to be a full-frame lens, I can't give it a recommendation.

It's good for a 100 € zoom on APS-C, but on full frame, you better spend the money for a lighter and faster Pentax F or FA 50mm lens. The focus ring has AF and MF setting, but you can just leave it on MF and still use AF.

  • Handling: It's a bit weird that the lens gets longer towards 24mm, but I could live with it.
  • Aberrations: Visible towards the corners, but can be corrected in Lightroom.
  • For my landscape photos, the 24mm setting is most important, so this lens is quite useless for me. Unfortunately, I can't give this lens a high rating for sharpness. So here are some 100% crops at different focal lengths: De-centering can't be the reason either because the left corner looks just as bad.

    There is a huge difference in sharpness between the bottom center and the corner. It looks like the corners could be out of focus at large apertures, but that was not the case, as this 50% crop (24mm, f/2.8) from the bottom right shows. This is the view which I used for my test images: The overall performance is best around the 50mm mark, but I didn't buy a heavy zoom lens to use it only at 50mm.At the long end, sharpness is much more even across the frame, but you have to stop down to f/11 to get a sharp image.At the short end, the resolution in the center is already usable at f/2.8, but the corners are very soft even stopped down.This lens is a bit of a disappointment in this regard. When I test a lens, the first question is always: Can it deliver sharp images across the frame? Aberrations can be corrected in Lightroom, soft corners cannot. So when it showed up on Ebay for around 100 €, I gave it a try. This lens has one, although it doesn't look like it on the product image on this page. Sharpness: 6 Aberrations: 8 Handling: 7 Value: 7 Camera Used: K-1 Autofocus: 8 New Or Used: UsedĪs I like to use my lenses with both film and full-frame digital cameras, I've been looking for a good standard zoom with an aperture ring.
