If you are using the flash as the main source of light, it won't matter, since the flash pulse is usually much, much faster than the sync speed. Details below, but if you're primarily lighting with flash and are at less than full power, the shutter speed is irrelevant and your exposure will be something like ¹⁄₁₀,₀₀₀th of a second. If, instead, you are ...

I use a Nikon mount Sigma 15mm (22.5mm equiv) f2.8 lens which focuses to within 3cm to 4cm in front of the lens on a DX camera. Stopped down to f11 or f16 there is considerable depth of field. Paul Harcout Davies and Clay Bolt have written an eBook on the subject of "Wide Angle Macro Photography. This link points to an article on Wide Angle Macro ...

The first and easiest thing for this is to get a 52mm close up filter. Example of this would be the Hoya 52mm close up kit I'm going to start out with pointing out that this will be less than ideal in terms of quality (you're putting a single element uncorrected lens in front of your lens) and possible mechanical vignetting (where the filter obscures part ...

With wildlife, 300mm is considered the minimum focal length you want (if we're really talking wildlife out in the wild, and not backyard semi-tame beasties that aren't shy of humans). 400mm is typically considered a minimum for birds. So, it does in some respects depend on what wildlife you're most typically stalking, in terms of how large and how shy they ...

To @Caleb's answer I would add: the accuracy and speed of the focussing mechanism. How quiet the focussing mechanism is. Most lenses are accurate and focus precisely, but they do it at varying speeds. For example, the Nikon 55-300mm AF-S f/4.5-f/5.6 was a nice lens for portraiture and relatively slow moving objects but not animals because: 1) the ...

There are a number of guides to selecting lenses on the web -- you should read one or more to familiarize yourself with lens terminology. One you could start with is this one from gizmag.com. Briefly, like many engineering endeavors, designing a lens (and choosing which to buy) is a matter of tradeoffs. You want to build (or buy) the best product possible, ...

The general rule of focal length for animals is that too much is never enough. It basically comes down to how much you can afford and are willing to carry. Many nature shots will be in remote places, so lugging the equipment there is a serious consideration. That all said, I'd at least want to go out with a 300 mm lens (relative to a full frame sensor). ...

Richard, IMHO you mix a little bit things. You need magnification of the lens. And most of the kit lens have magnification 1:5 which is 0.2 and it's enough to see the hair on the image. I find in one old answer here, in StackExchange formula you can use to calculate how big will be in sense of pixels one real object: How do I calculate the distance of an ...
