Sigma 28-70 vs Nikon 28-70

Discussion in 'Lens Lust' started by JohnR, Apr 26, 2007.

  1. Talking with my brother via iChat about lenses and he is wanting a good all around lens but not an expensive one.

    I found the Sigma Zoom Wide Angle-Telephoto 28-70mm f/2.8 EX DG Autofocus Lens for Nikon AF-D for $399 at B&H.

    My question is...it's got the same f stop as the Nikon version...so how is this lens? Does anyone have one?

    I have the Sigma 28-70.. awesome lens.. kinda wish it was a 18mm-70mm but i like it alot. I got it for 140.00 at a local store.

    Very nice Lens.
  3. Local stores here don't sell Sigma. Why do you wish it was 18-70?
  4. 28mm on digital isn't wide. 42mm in 35mm equivalent. I feel the same way sometimes, thinking I could make do with a 28-75 Tamron but I know I would miss the wider angle 18mm gives.
  5. Hi John...

    When I was looking at getting a mid range zoom, I was told with the Sigma lenses, that the way to go would be the Sigma 24-70 f/2.8 as this lens gave a lot better IQ than the Sigma 28-70. The biggest disadvantage of the 24-70 is the front element size, 82mm, which make for expensive filters (CP, Neutral, etc), other than a UV filter to protect it. Plus it is just that bit wider at 24mm.

    You may also consider the Tamron 28-75 f/2.8 as this is considered a very sharp lens for its price. Also a very sharp lens but not an f/2.8 is the Nikon 24-85 f/3.5-4.5 & the Nikon 18-70 f/3.5-4.5, still worth a look... But if your Brother is just looking for a general walk around lens, you couldn't go far wrong with the Nikon 18-135 f/3.5-5.6, this is a sharp lens and at about the price range you mentioned, has a good FL...

    Good Luck with you decision.....

    What about the Sigma and Tamron 17-50mm f/2.8 lenses then, if you don't need the 50-80mm range. The Tamron 17-50mm is a real gem and "you get what you pay for" definatly doesn't apply to this one.

    Hey John,

    I have the Tamron 28-75 f/2.8 and love it. It is an incredibly sharp lens and stays on my camera most of the time.

    If you are worried about the 18-28 range, then it may not work for you. When I need that range, I just throw my 18-55 kit lens on which has always been good.

    I know Snakeman bought the Sigma 24-70 not long ago and ended up returning it. He said it was nice and sharp when stopped down, but real soft wide open. One of the things I like about the Tamron is it's sharpness at all apertures.

    Here's a photo from the Tamron wide open with no PP other than sizing:

    Is that at f/2.8?
  11. I can only speak for the Nikon 28-70 f/2.8 as I have not owned the other mentioned, but if I had the available funds... I would definitely get the Nikon.

    I'd also like to add that I'm usually the first to recommend a cheaper lens that does the same job for less. Unfortunately, nothing I have found compares in image quality, color rendition and sharpness for a portrait zoom.

    I would like to see a comparison between the two, but I don't think anyone here has both lenses?

    Would be interesting as I hear the 28-80 is a bit soft wide open and is much better stopped down and to see how the Tamron compares.

    Yep, that's taken @ 2.8 with no PP other than sizing for posting.
