I'm looking for a lightweight telephoto lens for my Nikon D700 body, with a focal length around 300mm, good sharpness and AF. After several days with the 70-200 vrII handheld, I found this lens too big and heavy. I usually prefer the prime lenses, but all the good ~300mm prime I know weight 1.5kg or more.

I will use it mostly for sport, wildlife and landscape. A bonus point if it is bright enough for a use in dark concert stages :)

The only two lightweight options I considered for now are


Nikon 70-300mm VR (750g, F5.6@300mm)
Nikon 180mm (760g) + 1.4x TC (F4@250mm)


Have you any recommandation on these possibilities ? e.g. with third party lenses.
I'm in love with my 85mm 1.4G, but I have the feeling that I won't be able to get the same quality at 300mm without carrying expensive kilos of glasses.


Question: iPhone app - Persistent hamburger menu vs last page visited
Answer: Always have your navigation persistent.

But that doesn't mean you can't have a "back" button in place when it's needed when you dig deeper on portions of the site.

Now this is just for the sake of your answer, but I highly suggest against the hamburger menu. Many products (twitter and Facebook to name a few) have moved away from the hamburger menu because of various reasons:


Discoverability was at an all time low
Not a lot of people understood what the hamburger menu was


They all placed a navigation element that was persistent on the bottom of the page, where people could toggle between what they knew were big hit points on the site (timeline, discover, messages, etc).

Some examples:
