Since people asked... Here are some outdoors comparisons...
First thing I must say is the new lens is exactly 10% brighter. For this comparison, I adjusted ONLY the brightness and made them both as close as I could.
At first glance, they look almost the same. There are 3 crops. Center, Left and Right.
Not only the old lens gets blurry on the edges, but also the horizon line drops significantly! I drew a red horizon line on all crops to illustrate the effect... The new lens has an almost perfect horizon line all the way thru... Amazing!
Sharpness is just awesome. The buildings on the center are probably 3 miles away and the 2 towers on the right hand side are over 6 miles away... Still there is enough detail in them and this is just a 70mm lens.
Check out the Subway billboard on the right... Unbelievable!
I am not a landscape photographer but I used the lens for the first time to shoot a model. In another forum topic I complained about how many out of focus or soft images I was getting out of my 1D X. I was disappointed and frustrated. I must say that I didn't miss any today. ALL images are super sharp and the focus is spot on! I am happy again! The old 24-70 will be on ebay tomorrow!
Here are the links to the comparisons... Just rollover the image to switch and prepare to be amazed!
If you are an outdoors photographer, the perfect horizon line and the sharp edges should be a life changing experience
One more Thing. Since the lens is brighter, it seems more light goes into th sensor, it is even better for low
Light situations. I would guess it's
Like 2 stops brighter. At the studio, When i used to need ISO 640, today I used ISO 400! Same
Lighting setup! Awesome!
Hope u enjoy!
