What is the 35mm equivalent focal length of this lens?...TIA

The 35mm equivalent focal length is about 45mm. This is an excellent focal length for room-distance pictures of people or general landscape photography.

If you're using on the APC-S type sensor (i.e. like on the Sony a6000) there will be a crop factor of about x1.5 (so this is equivalent to about 45MM --> 30 * 1.5) - oops - looks like this was already answered below. Great lens - not as sharp as I was expecting in low light - for which situation you're better off with Sony's 50mm f/1.8).

For a Sony E-Mount camera such as an NEX-6, this lens will equate to a 45mm.

On your camera (a 1.6 crop frame camera) you have to multiply ALL lens focal lengths by 1.6 to get the 35mm full frame equivalent. The 10-22mm will behave like a 16-35mm and the 17049mm will behave like a 27-64mm

No; it is a fixed focal length lens. It is the equivalent of the "ideal" normal lens on a 35mm camera.

You are absolutely right on that Scott. The 35 1.8 is also a Chinese made lens. Same here ... that 35 1.8 was the first lens on my D90 (which is made in Thailand) and is still my go-to prime lens. I feel like this 85 mm is definitely more a portrait lens given the effective focal length on the D90. It performs superbly tho. I think the only two Japanese lenses i own are Toknia's. I don't understand why its important where a lens is made tho? Is it about the QC??

Multiplying the 17-40mm EF L by 1.6x = 27-65mm equivalent focal length. ALL lenses will be multiplied by 1.6x on your camera, regardless of whether they are L glass or not, because you are not using a full frame (1x) camera. But if you EVER plan on getting a full frame camera, keep in mind the EF-S lenses will not work. Though they're pretty easy to unload on ebay.If you don't plan on getting a full frame, this is the way to go: 17-55mm f/2.8 IS USM.

The lens is quite sharp at f2.8, I have no hesitation to use it wide open. If it will work for your purposes will depend more on your lighting conditions and the maximum ISO you feel comfortable using on your camera gear. If the light level is really low, you might be better off with the Olympus 75mm f1.8, but the cost of that lens is much higher. The other question that only you can answer: Is this focal length long enough, at 120mm equivalent for 35mm, long enough for your sports needs? The Sigma is a terrific value for this focal length, very happy with mine.

No. 35 mm wont be able to focus. The focus point will be behind the camera. 50 mm is probably the minimum and even then you'll have to be very close to focus.

Why would someone compare a 50mm to a 35mm? Its not even the same focal length..

Yes. Specifications show that for the zoom, the 35mm equivalent is 24 mm to 120 mm. Standard is 50mm, so that should be plenty wide for your needs. This is a sweet little camera!

Yes, it's the equivalent of 35mm on a full frame digital or film camera (not 50mm), and the fixed focal length built into the Fuji X100 and X100S. It is the ideal 'walk-a-bout' lens.

16-50mm is the focal length. For a lens cap you need to know the filter diameter, I think it is 40.5mm for that lens.

Or the 35mm F1.8 AF-S which is closer in price to this lens. (I have the 35mm and its fantastic for what that is worth).

Sensor is 1/4.85" type, as per Canon's website. Crop factor is 13,75x of 35mm, as per focal length equivalence.

Assuming you are referring to the equivalent when used on a DX body, and that you want to use this lens on a DX body, such as the D7000, the crop factor is actually 1.5. So that means 14x1.5= 21. Thus when compared to a 35mm (FX) sensor this lens works similarly to a 21mm lens.

55mm. Not quite sure why it is so large, but that is what it is. Not that you asked, but I am very happy with this lens. Using on a Sony a7R with the LAEA3 adaptor. Images are sharp with good contrast. Lens hits way beyond it's price point.

If you look at the edge of your lens around the glass there should be a very fine threading on the inside edge. That is what this filter threads into. Also, there should be a bit of info around the rim of the lens that provides manufacturer, f speed of the lens, and the diameter. For most normal 35 mm lenses the diameter will be 52 or 58 mm. If you lens says 52 then this filter will fit. If you can't find the threading or the diameter info, your lens was not built to take standard add-on filters.

Per Nikon tech specs the lens focal length is 5.1mm to 25.5 mm which is equivalent to that of 24-120 mm lens in 35mm format. So the widest angle in 35mm format is 24mm.
