Ouch. I wonder what the new Sigma is going to be like? It would be a shame (for Nikon) if the Art and/or the Tamron would outdo this fancy Gold-ring unit. :)

Yes, I'm curious, too. However, the Sigma MTF charts don't look too promising.

To me, this 24-70 region was never tempting. But if it was, I don't know how to decide: The asparagus looking Nikkor with nice focus and zoom rings or the big fat Sigma with a (too) small focus ring? Sigma makes some fuzz about special aspherical elements for better bokeh and the OS to be improved (and the one of 24-105 already is very well performing).

 

But price and weight are still "TBD", so let's see what they come up with. Edit: Just seen the weight, 1kg, what a surprise bored20x18.gif

Markus, thanks for this review.

And this is at 24MP sensor, I assume the measurements will be worse on sensor with higher MP.

One small change is needed: "light fdall-off".

Markus, is it possible to post pictures to show the drop in resolution at 70mm f2.8 compared to 24mm f2.8. The drop is quite significant.

The bad CA is most surprising. The example images seem to have most CA "corrected" though??

I just double-checked: CA correction is definitely not enabled in C1. I'm afraid the sample images just don't have enough harsh contrast to provoke it.

It's very visible on the distortion chart, though. This is a 100% crop at 35mm:

Usually you don't need that high a contrast for the CA to be noticable. I guess the blue/yellow nature makes it a bit less noticable than for instance magenta/green.

 

Are the CA colours consistent though the focal range, or do they change? You can see that with some standard zooms. As far as I can tell from the sample images, it is blue/yellow throughout the range.

Yes, consistently blue/yellow.

Ok the sample is good and hard to explain CA and vignetting by sample variation, quite a disappointing review, however would it be possible to test another sample ? the results seem too bad to be true.

Sorry, no retests. We are already doing entry tests to avoid lemons. If this was a bad sample the MTF charts would look more erratic.

  OK this is a thanks for the warning style review........

   

  ......surprisingly uninspired sharpness from 50mm up at the borders, poor vignetting and CAs...     and all this from a top of the range  expensive OEM lens...huge heavy and expensive! 

 

  I suppose the question is: Is the Tamron better?    at the longer end it looks to be, has better CAs and can be bought for a lot less money!

The Tamron OR the Sigma  ;)

 

Meanwhile Nikon users do have nice choices. Maybe someone should tell Nikon about that.

The Tamron had its share of gotchas as well methinks - like vignetting and distortion - but the resolution seemed better in both Canon- and Nikon-based tests. And then, the G2 version is looming...

The Sony 24-70mm f/2.8 is probably the only fast std zoom lens that is good. I don't expect anything from the new Sigma and Tamron.

But then this is a useless lens category - not really fast, excessively heavy and big, very expensive relative to what they offer. PERSONALLY I couldn't care less.

Something like the Canon 24-70mm f/4 makes more sense.

But we are all different.

Same here. I just think, wedding and event photographers like it very much. I'm neither that nor the other.

Go tell this to wedding photographers for whom this lens is an absolute standard

the classic Nikon  trio almost every professional photographer using Nikon has   14-24/24-70/70-200

 Yes, the Tamron is less sharp at wider angles but better at the long end, vignetting is almost a stop better as are CAs......this is disappointing after the "rabbit from the hat trick"  70-200mm E VRII.  

  I don' t know how much the Nikon is, but I see it at well over two grand, the Tamron can be had for less than "a" grand, so the latter has some good excuses!       Bring on the G2!  

 

  Gotchas from the Tamron?  .....a few ..but financially the Nikon will have gotcha by the short and curlies..  :o

 

 The Tamron at 70mm focused closely was less than 45mm effective FOV, How's the Nikor here?

As those are the only goldring zooms Nikon has to offer with f/2.8, there's not much of a choice.

 

One can find comfort in the knowledge the 24-120 and 24-85 are much worse  :D
