what is the standard lens field of view

The official specs from Olympus's website indicate a 25mm-100mm (35mm equivalent) focal length range. http://www.getolympus.com/us/en/tough-tg-1.html

The lens itself is 4.5mm at wide and the listed 35mm equivelent field of view is 25mm.Sorry, N. Hoang; I didn't see that you had beat me to it.

well, on a standard 35mm, the diagonal is 41mm, so therefore the standard would be 41mm. i have not measured the size of the tg-1 sensor, but the standard would be roughly the diagonal. if you want it in zoom equivalents, the widest is 25mm, 2x zoom is 50mm, 3x zoom is 75mm, and 4x would be 100mm. so, if you wanted the leica standard 50mm, shoot at 2x, and if you want the real standard use 1.6 or 1.8x (mine will not do 1.7). hope that is helpful.

The standard lens is a spot. The Wide angle creates a horizontal rectangle of light. The ideal set up for night mountain biking is to have the spot on your helmet and the wide angle on your handle bar. Works great!

This lenses for different tasks.14-45 (28-90 in 36mm equivalent) is a good everyday lens. I use it as a standard lens for every day shooting.45 - 150 (90-300 in 36mm equivalent) - this is a telephoto lens.

About six inches. Probably a little less. One of the huge benefits of this wonderful little lens!

This lens is equivalent to Nikon's 55mm f 1.8 lens. It is considered a "Normal" lens meaning it 'sees' like the human eye. While it can used in daylight and low light it is NOT a wide angle lens. If wide angle is what you are interested in use the 10 mm N series Nikkor lens or one of the zoom lenses such as the 10 mm to 30 mm zoom or the 10 mm to 100 mm zoom, which is my preference.

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.

basically, the same size as the reading lens in a pair of bifocals. you can trim them if necessary

Eyepiece (rear lens)is about 17.5mm, front lens is about 22.5mm. Excellent sight.

Micro Four Thirds is a lens mount standard with a great many lenses available from the primary member makers, Olympus and Panasonic and a couple of others.There is a list here, which links to details. http://www.four-thirds.org/en/microft/lens_chart.html

The user guide says that the "field of view is fairly small. It is approximately equivalent to the field of view through the telescope when looking through a typical (i.e. not wide-field) 5mm focal length eyepiece." So maybe 200x ?

There is no view finder. The lens is a wide angle type and I've not had any issues with it not picking up a good field of view.

Depends on the camera. On an APS C sensor like the Pentax K-3 or K-5 the 35mm is the "natural" focal length to get a field of view about the same as you get with your eyes - it's like a 50mm on a full-frame camera. I have an Pentax A 50mm I use from time-to-time. On an APS C sensor it's like a 75mm on a "normal" full-frame camera.

In regards to Yug's comment about the 1.5x zoom factor ....This is not entirely correct as any lens will give you a 1.5x zoom on a DX camera, even a lens designed only for a DX camera. So either lens will give you the same field of view when zoomed to the same focal length.

I can't specify "field of view," but what I can tell you - that I think is important for you to know - is that when I replace a 10x eyepiece in my low-power binocular microscope (1x objective), the image is greatly magnified from what it would appear through the eyepiece . . . perhaps about 5x as much (50x total?). I really would have liked it to stay the same, but I can understand why it doesn't. If you have a 40 or 50x eyepiece (or so) that you replace with the camera, my guess is you will see about the same picture as you see through the eyepiece. The clarity is good. Of course, it could be better, but probably not for the same price. Now that I understand the limitations, etc., I am quite pleased with it. I built my own lens and stand for it, using the barrel of a cheap flashlight and a double convex lens that just happened to fit the tube perfectly (24mm). I added a diaphragm to increase depth of field, and a baffle between the lens and camera to minimize "splash" within the tube. These are all held in position within the tube by O-rings (from Harbor Freight). The added diaphragm requires an additional light source, which I got from eBay for $3.50 (music stand LED lights on flex arms). Works pretty good!

Here are some useful links to sort out field of view. You may want to look at the 4-9mm model if you seek a wider field of view. I have the 4-9mm on my garage looking across the street and the 8-20mm looking at my front door. Overall good for the price.http://www.homesecurityguru.com/cctv-camera-lensesVideoSecu Outdoor 700TVL Day Night Security Camera Built-in 1/3" SONY Exview CCD II EFFIO-E DSP 65 IR Leds 4-9mm 3X Zoom Lens for CCTV DVR Home Surveillance with Power Supply and Security Warning Sticker CJZ

Yes. The field of view is very large. The lenses cover a pretty wide area, as well as top to bottom. This combined with the completely adjustable angle and lens placement afforded by the adjustable hinge joint allows you to have an extremely large sweet spot with the lenses. This meshes beautifully with progressive lenses.

Range is actually the Guide number divided by the F number of the lens. With a typical f3.5 to 5.6 kit lens the range at ISO 100 will be 18.5 Ft @f 3.5 and 11.6 FT. @ f 5.6. If the ISO is increased to ISO-400, the range @ f 3.5 is increased to 37 Ft. and will be 23 Ft. @ f 5.6 Only at ISO-800 can the range extend to 65 Ft. and then only at f3.5.
