At what aperture is it when it gets to around 50-55mm? Thanks.

Just buy the lens, you will be happy with the photos. If you were to google for the lens review I am sure you would have found this:http://www.dpreview.com/lensreviews/sigma-17-70mm-f2-8-4-os-hsm/2I shot this whole set using the Sigma lens:https://www.flickr.com/photos/73423234@N00/sets/72157650552650126/

Somewhere around the 4 mark. It's such a great lens. I don't think you'll regret purchasing it, truly.

An 18-55 mm lens is generally used for portrait type photos as well as medium wide angle photos. I use it both for some nature shots as well as many family group photos. The only time it lacks capabilities is very late in the day when light is very low - depending on your camera you can dial up the ASA speed to overcome that.

Hi Vanessa, For amazing bokeh / background defocus, we would recommend the 50mm. -Anthony

I would say at max zoom it extends to about 6 inches. I don't have it to measure. Search on youtube for some demonstrations, that is what I did. Great lens!

how does it do in small spaces. We cruise some and it's difficult if not impossible to take a good picture inside our cabin. With my fixed 55 if i aim my picture on the door knob 5 feet away, i get the door knob and a little of the door. would this lense be able to get the whole door?

I guess it really depends, the 50mm is fantastic with a really nice shallow depth of field but the 50mm is worthless for a family portrait in a small room, heck, even in a large room its rough! I use the 50mm for individual portraits but for a group its focal range with the crop sensor just sucks. I use the 28mm for everything inside my house, crawling baby, family photo, etc.

It is 2.8 at 50mm and 3.5 at 200.The scale is fairly linear - it is about f3.0 at 135mmSharpest at f4 and still quite sharp wide open.

Since this 16 is no really a wide angle lens you can go with the 18-55 but you will not be able to zoom with this lens. It is mostly a 16-18 in the housing, you can't go out to 50. Works great and you can even get good close ups.

Hi Jorge, it's beautiful. I normally use the 50mm 1:1.2. I'm spoiled and prefer this over any zoom.

While this lens performs well in a fairly wide variety of situations, I would recommend the Nikon 35mm f/1.8 af-s dx or the Nikon 50mm f/1.8 af lenses for portraits. Either of those will give you much better performance in lower light situations and they are both very sharp lenses. As I said, the 18-55mm is a great lens but if you want to focus exclusively on portraits, go with one of the others instead. I actually prefer the 35mm over the 50mm. Just my two cents though.

The 18-55 covers a widw ange to short telephoto range equal to a 27mm to an83mm lens on a film camera. with this lens you can shoot fairly wide shots and the zoom in to increase the size of yor subject . the 55mm end is good for portraits and the 18 is good for scenics. The 55-200 zooms out to capture firds in flight or othe distant subjects. Both are inexpensive and outstanding optically.

This is a prime 55mm lens it doesn't zoom. It is a fixed focal length. It is 55mm on the full farm A7 & A7R and the equivalent of approximately an 82mm on an APS-C sensor camera.

It is a 500mm lens with a 2x adapter. Manual focus and at f/8 really only good with lots of light. But fun to play around with and compact in size, limited uses.

This is a great portrait lens. I would say a mixture of 50mm and 85mm would do. This is a great lens !

58mm. Great lens. I used mine today and it's very nice. Recommend B+W filters. A bit pricey, but the whole package is excellent quality with those filters.

Actually, I'm merely guessing on the focal length from your inquiry about the 17-55mm. Your choice will depend on how much reach you actually need. Some suggestions: At $80, the Canon 50mm f1.8 is very inexpensive with pretty good optics and a wide aperture. Focusing may be too slow for your needs but its so cheap it might be worth a try. The Canon 50mm f1.4 adds fast USM focusing and somewhat better optics. The Canon 85mm f1.8 is a good choice if you need more reach. The Sigma 30mm F1.4 EX DC HSM get pretty good ratings and is a good choice if you're fairly close or need a wider view.

Hey there.I would suggest an exercise if you have the 18-55, but want to start shooting primarily with a fixed focus prime lens. Set the 18-55 to 50, and take shots for the next week only at that length...50 serious shots should give you an idea if you like it as a walkaround. Since there is a really nice sony 35mm lens as well, try that length out also. Personally I like 24mm or 35mm as a walkaround, 50mm is a little too telescopic but it is a very personal preferance.
