  • Had both Sigma 17-50mm OS and 17-70 OS C version.  So comparison is btw those two. 17-50 is significantly sharper through out all its range 17-70 has better range, lighter and focus closer (1:3) Bo ...
  • Took Sigma 24-105OS + Nikon 16-35VR.  About 70/30% splits for two weeks in Rome/Florence. 16-35VR is really good inside dark Museum.  Can't use a flash or tripod.  So use high ISO and VR to ...
  • For slot canyon, UWA zoom 14-24mm is a great choice. Often need to zoom in and out quite a bit. 24-70 actually works quite well actually. Lots of places will require a short telephoto to take a ...
  • I had a Sony A6000 once. Loved the weight and control. Did not love the lens choices and price.

    Was looking at FF mirrorless. I noticed that there is almost no weight difference for similar IQ...

  • If you can figure out a way to make similar IQ on half of the weight on a FF lens, that would be a true optical break through. And you will be an instant millionaire.

    Otherwise, stick with crop...

  • Replied in Imagine that
    That's funny. I have owned 5 Rolex, 1 Patek and 1 Omega watches in my life and none of them are as accurate or precise as my iPhone; however, I still refuse to buy a iWatch and wear my Rolex ...
  • Had crop camera from both systems.  Nikon D7100 and Sony A6000.  So these are my personal experiences: 1) Nikon has much better and less expensive lens choices overall.  Sony A6000 normal zoom ...
  • This is the non HSM version.   I had it in CAnon version.  Very soft wide open.   HSM version is better in the center area but just as bad at the corner.    HSM also has faster AF. On Nikon body, ...
  • Had 24-85VR w/ D800.  All my gears were stolen on vacation last July. Bought Sigma 24-105Art w/ D750. Don't have any experience with 24-120mm VR Comparing Nikon 24-85VR and Sigma 24-105Art, the ...
  • Had Sigma 17-50 OS w/ D7100. Excellent combo for landscape to single person portrait. I did find it a bit short once in a while. Bought my son a D7000 + Sigma 17-70C OS. Excellent combo. Very nice ...
  • Sony just bought out Toshiba's sensor business
  • Just got D750 w/ Sigma 24-105Art in the last month.   It's quite a heavy combination @ ~3lbs total.  Although Nikkor 24-120 is not much lighter.  Perhaps not the best combination for travel lens ...
  • One point needs to be brought up.  There are quite a few different version of Sigma 17-70. Early version is 17-70 2.8-4.5 -non OS Later: 17-70 2.8-4 OS Latest version: 17-70 f/2.8-4 OS Contemporary ...
  • Just to make It more interesting.  There is a sale on sigma 17-50OS for $300 on buydig.  Add to cart and you will see the price.  Now that's a great price for US authorized lens.  I still remember ...
  • Just checked the photozone charts for both Nikon 16-85 at 16mm and sigma 17-70 at 17mm.  Nearly identical charts at f/5.6 and slight better at f/8 for Nikon 16-85, but not likely to be visible wo ...
  • I just bought a Sigma 17-70 f/2.8-4 contemporary today after much searching.  It's a gift for my son to pair with his Nikon D7000.  Should cover a majority of his needs. Looked at Nikon 17-55, ...
  • Most of the readers on this forum are hobbyist looking for advice. in term of logical business practice. You should charge the maximum that market will bear. If two lens can do exactly the same, ...
  • The high price of NIkon 16-80 might be coming to an end faster than you think. Nikon sells a D500 kit with Nikon 16-80.  by Xmas time when D500 kit is more plentiful. Retailer will start to take ...
  • For me, every lens purchase is always about price per performance.  In this case, I just don't see the worth of the lens because the competition is quite strong. I am not going to pay twice as much ...
  • Never read a out-right bad review on 16-80.  Every review said the same thing.  Good IQ light lens with excellent coverage.  The concern is always on price though. The competition are typically ...
