Nikon 600mm f/4 and 400mm f/2.8 FL VR AF-S G NIKKOR vs Sigma Contemporary 150-600mm

Can you see the difference between these nikon vs sigma lenses? Yes. Is it worth $11,000USD more? Mmmmm sure, because it shoots at f/2.8 and the other at f/6

The top Nikon glass is made for sports photographers who need the aperture and reliability. They keep working and won’t complaint. Not to say the Sigma doesn’t, but its not made to withstand the abuse like the Nikons. If it breaks, you can buy 10 more. But you will never be able to shoot at f/4 or f/2.8?

Rokinon XEEN Lenses

Just got 2 Cine lenses. From the reviews of some users, say they are pretty sharp. I’ve only had time to shoot one quick teaser for an upcoming video and that 85mm XEEN has a nice look to it. Both lenses feel solid, the focus rotation is smooth and very precise for my use. I may compare them to Canon L glass this weekend if I have enough time. 

   
 

That 24-70mm f/2.8 is great but my 28mm f/2 is better for me.

That Canon or Nikon 24-70mm f/2.8 is a great lenses, covers most of the focal length you would want and need for most of your life but for me, that lens is missing one important thing for my style of photography and it is bigger aperture. Even one stop difference from f/2 to f/2.8 you are looking at ISO 3200 vs 6400 and if you really need a bit more for natural light add a two stop difference ( f/1.4 to f/2.8) and you are looking at 1600 vs 6400. Some modern cameras of 2015 can shoot above 6400 and still produce usable results but as of today I don’t shoot beyond 6400. I am also forcing myself to shoot with wider lenses and create compositions using the background in harmony with the foreground. I would like a Summilux 28mm f/1.4 but in a Summicron size and since that won’t happen I am reviewing the 28mm Voigtlander Ultron f/2. The lens isn’t very sharp at f/2 but gets sharper than the 24-70mm at f/2.8 but then it suffers from little focus shift at f/4 through f/11 so until I save for that Summicron 28 or give into the bigger Lux 28 I will shoot with this Ultron. 

Below is a comparison to the sharpest lens I have access, the Lux Aspherical 50mm, it produces very organic neutral color, amazing detail and marvelous control of blurred areas while the Ultron gives you a cooler temperature rendition and less color control.
