What is the f-stop of the 50-200mm lens also included with this camera?

It has auto focus so depending on the lighting it will autoset the F-stop. You can view the ISO and F-stop used in the view screen.

The f stop (aperture) of the zoom lens changes as the zoomed focal length changes. On the P7700, which should be the same for the P7800, the f stop changes in the following seven steps as the focal length is zoomed from 28mm to 200mm: 28mm - 2.030mm33mm35mm - 2.238mm42mm - 2.546mm50mm - 2.858mm66mm - 3.274mm85mm92mm105mm - 3.5117mm135mm152mm175mm - 4.0200mm

Which lenses? In any event, the f-stop is printed on the lens, either on the barrel or the ring around the glass at the front. For instance, on my 12-50 mm zoom the f-stop range is 3.5-6.3 and is written "1:3.5-6.3". F-stop is the ratio of the diameter of the lens opening to the focal length, so on a zoom lens the maximum f-stop depends on the focal length the lens is set to. The longer the zoom length (20 mm vs 45 mm for example) the smaller the f-stop. Know that the scale is reverse, the more light a lens passes the closer the f-stop number is to 0. For example f/3.5 passes way more light than f/11. Do an online search for "F-stop" and you should find a reference to a Wikipedia article explaining it. Hope you like the camera as much as I do.

Have you got a 52mm lens for it like the 35mm f1.4 or the 18mm f2? In that case, YES ;)

The min and Max f stop are listed in the description.. F3.5 to F5.6... But it also depends on your focal length or iso... It can be up to f22 at 55mm

I'm almost sure youre lens is good. As it is a prime lens, you cant control the f-stop with the camera body, so the the camera can't detect that there is a lens attached as it would with your kit lens. Go into your camera's menu, go to the section designated by the picture of the gear. Scroll down until you see the option that says "Release w/o lens" and enable it. You should be able to use the lens now.Hope this helps!-Andrew

Hi Viviana - Lens is included - the only disappointment is that it does not take 5 - 10 shots in a second as advertised - more like 3 or 2 - light weight is a nice unmentioned feature

Yes. Sounds like a faulty lens. It works at all f stops. Check if there's a ton of dust in the back of the lens, but that's about all you can do. Also make sure that the camera works with other lenses at other f stops, so you're sure it's not the camera.

It appears to be the 200 mm. I have not measured exactly per say but it does zoom out that much and it works really well. I keep it on my camera unless I am doing some macro work.

The f-stop is always going to show f/2.8 on your camera.However, on an APS-C crop body such as NEX-5 or NEX-7, in terms of Field of View and Depth of Field, this lens is equivalent to an 52.5mm f/4.2 lens.

I just checked the website for Focus Camera, it does include the 16-50mm lens. FYI, if you were looking to catch the deal before it expires, you have time since the rebate for $100 off holds until 1/4/2014 per their site. I hope that helps!

The 2 lenses are good, but the main difference is on how sensitive the lens is. In the one i bought, it's lowest f-stop is 4. you need more light for avoiding grain. The one you are referring to works better in a low light condition (f 2.8).

The 28-300 is more of an all around lens. It is powerful enough for both wide angle and telephoto. The difference of the f stops is not that drastic. I have the 28-300 and used it only in Africa for two weeks and have hundreds of great pictures, many that the 70-200 could not produce.

Yes it does. That is the purpose of the 1.4 f-stop to let in the maximum amount of light. When shooting in a low light situation where flash is not an option this is the lens of choice.

Yeah , I can now confirm it myself as well. The package includes the lens, 58mm to 52mm conversion ring, small bag and 2 covers for the both ends of the lens. I wonder why Amazon does not give accurate info in the technical details section.
