Tamron 15-30mm f/2.8. One of my favorite wide angle lenses I’ve used is the Tamron 15-30mm f/2.8. It’s a heavy lens, but it matches or even exceeds the Nikon 14-24mm f/2.8 in image quality overall – plus adds some modern features like vibration reduction and a water-repellant front element. The AF-P DX NIKKOR 70-300mm f/4.5-6.3G ED features the superb optics and advanced technology used on Nikon's high-end lenses. Your photos and videos will have rich, vibrant colors, deep contrast, minimal distortion and beautiful soft backgrounds, even in less than ideal conditions. And, even if it is not so, the correct way of holding a camera for maximum stability involves holding the lens and resting the body (if possible) on your palm. – ysap. Mar 31, 2011 at 11:15. The Nikon 14-24 f/2.8 and 24-70 f2/8 come to mind as a rather short lens (13cm, 5") that weigh about a kilo. The Nikon D3100 is 30 grams lighter than its predecessor, the Nikon D3000, with a weight of only 455 grams without the lens, making it the lightest Nikon DSLR camera. The Nikon D3100 is largely made of plastic, with the exception of the metal lens mount. The final lens on our list is our Sigma Prime lens for Nikon d3100 cameras, the Sigma 50mm F1.4 Lens. Although coming from Sigma, this is a third party lens for Nikon d3100 cameras it offers excellent quality and the lens has an amazing reputation within the photography community . But the 70-300 f/4-f/5.6 is listed as an AF lens, meaning that it needs a camera with a motor for autofocus. So that lens won't autofocus with a D3100. But all the exposure modes will work. The newer 70-300 f/4.5-f/5.6 AF-S lens will work with all Nikon DSLR's and is a much better lens besides. -- Leonard Migliore. The Nikon D3100 has got external dimensions of 124mm x 96mm x 75mm (4.9" x 3.8" x 3.0") along with a weight of 505 grams (1.11 lbs) while the Pentax K-50 has sizing of 130mm x 97mm x 71mm (5.1" x 3.8" x 2.8") along with a weight of 650 grams (1.43 lbs).
