I believe the minimum focal length was around 35 feet. This was a pretty good scope for the price. However, the front lens is held in be a really flimsy plastic retainer. Mine broke after about a year. I'd suggest a Bushnell sentry scope, more pricey, but they have a bullet proof warranty.

That is correct the aperture is 100mm. The first set of numbers [22-67x] indicates the magnification capability of the optic. On the other hand the second [100] indicates the aperture if I'm not mistaken.

No, the lowest magnification is 10× anything less than 25 yards is hard to focus in and even 25 is a bit hard. This is good for 50 yards and more.

I do not own this lens anymore do to the fact that I started shooting indoor events. I loved the lens but with a 4 aperture it doesn't take in enough light. I would recommend the 2.8 version of this lens or a prime lens for your needs. You will be able to keep your shutter speeds up and ISP down.

I'm not sure if I understand your concern of DOF issue with 1.8, but you can always change your aperture to 8~9 and it will show details of your back-ground. But If I were you I would take a 18-200mm instead. covering wide to fairly good zoom unless you are planning to do dark inside building pics. That's just my 2 cents.

The aperture is about 3/8 inch in diameter. So big for a single skinny telephone cord, but fine for two or three two-wire power line cords.

It needs to be smaller than an 80-200 f/2.8 to fit. Many 500 mm lenses are longer.

Hi,there isn't a physical aperture setting on the lens,but I shoot with a Canon T3i and adjust it with the camera's aperture wheel. f/3.5-22...

Don't forget to manually adjust the aperture (the adjustment ring on the adapter). Wider aperture - &gt; more light gets in.

You probably mean using extension tubes, which would give you a much closer minimum focusing distance....

Minimum is not a problem at all, I can sit on my couch and use it to look at things maybe 10 yards away on my kitchen counter and I can see everything very clearly, and see the writing on seasoning shakers etc. The problem it has is out past 200-300 yards it starts to get fuzzy.

In order for any lens to be able to autofocus correctly, the minimum aperture after the teleconverter is added must still be f5.6. Therefore this lens with either the 1.4x or 2x would be manual only.

I was curious myself, so this is what I found on "Wikipedia" http://en.wikipedia.org/wiki/Canon_EF_75-300mm_lens It looks as though there's not much difference. The "II" minimum aperture is f/45. The "III" minimum aperture is f/32 to f/45. Neither model have "IS" (Image Stabilizer) nor "USM" (Ultra Sonic Motor) which is fine for me, because I almost always use a tripod with any telephoto lens

Try a 9mm,, 4mm is even better. I can see 4 of jupiter's moons pretty clearly when focused.

Naturally, the smaller aperture you use, the greater the depth of field. If you want to know the exact depth of field for this lens at various apertures and focal lengths, download the manual at Nikon. There are depth of field tables on pages 116-121. For instance, at f2.8 and 24mm, the depth of field when focused at infinity is 6.48m to infinity; at f8 and 24mm, it is greater: 3.11m to infinity--the higher the aperture, the greater DoF.
