The Virtues of using older lenses

This photo of the Ohio Club, in downtown Hot Springs, was shot using my old and trusty Nikkor 20mm f2.8 AI non-cpu manual-focus lens on a D800. It produced a beautiful color image with no barrel distortion or vignetting. This 20mm lens series is considered by many to be one of the best lenses Nikon produced. However, those that have only been in photography for a few years tend to over look these older AI (Auto Indexing), AIs manual focus prime (Non-Zoom) lenses when considering a lens purchase. There are many great values out there to be had.

Grant you, the budget level Nikon DSLRs are not equipped to handle these lenses, the D3000 – D5000 series cameras to name a few. To use AI lenses your camera will need the AI Tab, these cameras will also have the older style Auto Focus Pin, see photo on left below.

There is also a menu item to enter your non-cpu lens info.
It tells the camera what the focal length is and it’s maximum aperture. This info is then conveyed to various camera functions.

Panning Continued

WMGEN_5779A

Nikon D300, ISO 1600, 1/30 @ f3.5 and SB900

Continuing with the Panning Technique theme, from the last blog post, We’re going to add a flash to the mix. The purpose of the flash is to light the subject and stop motion in a night time setting.

Some modern electronic cameras include the ability to fire the flash just before the closing of the shutter known as Rear-Curtain Sync or 2nd-Curtain Sync. Your camera will need to have this function in order to achieve this effect (check your owners manual).

With the flash freezing the action of your subject, slower shutter speeds can be used to blur the background even more. But keep in mind, the shutter controls the available or ambient light exposure and the aperture controls the flash exposure. Adjust your ISO to give you a workable shutter speed and aperture that will give you a good overall exposure.
