Borrow lenses (and sports photography)

I received this e-mail:

Trust this finds you well. I am hoping I can impose upon your photography expertise with a question. My wife has been shooting our son’s high school football games (played at night under the lights) with our basic Cannon SLR rebel and using a borrowed Sigma telephoto lens that I think is an 18-200mm and there were some other specs but I can’t find my notes.

Anyway – knowing that the prime purpose is to shoot football games at night where the lighting is ok at best – and wanting a good amount of zoom capability – can you recommend some options in the $500 – $750 price range for me? Also a good retailer or place to buy such an item?

There are really two questions here: what is the ideal lens to buy for night (from the stands) night sports photography, and what is the best lens to buy in a given price range. The answer to the second question may be…nothing at all.

You can read on, or read an four-year-old article on the subject here.

Live view aperture on the E-P2

Now that my E-P2 has finally found a jacket-pocketable lens, the 20mm f/1.7 pancake from Panasonic (purchase from Amazon or Roberts Imaging), I’ve been carrying it a lot more often.

E-P2 w/ 20mm f/1.7

San Francisco, California, USA

Nikon D3, 50mm f/1.4G
1/50 sec @ ƒ/2.2, iso 2500, 50mm

A 20mm f/1.7 lens and a Hirano case make the E-P2 an effective kit. If you want to pocket it, just unscrew the case and pop out the EVF.

One curious behavior I noticed while shooting is that the aperture is electronically controlled to make the CCD’s life easier in the camera live view—since this is an EVIL camera, it always has live view. When it’s quiet, you can hear the aperture click as you move it around to different lighting conditions. Furthermore, it never seems to set the aperture wider than about ƒ/2.8 unless you are autofocusing. This means when night shooting in the dark with this lens, it’s brighter than your eyes, but not as bright as the lens is actually capable of. Not only that, but the depth-of-field you see in the live view is independent of the final output.

I decided to take a video of the behavior with Marie’s D5000. Since I accidentally hit the shutter button while focusing, here is a still:

Nikon D5000, 18-55mm f/3.5-5.6 DX VR
1/30 sec @ ƒ/7.1, iso 560, 55mm (78mm)

To get this photo, I jury rigged my D200 RRS L-bracket onto the D5000 so I could tripod mount it.

and here is the movie:

I’m just waving my hand in front of the lens a few times. And then I turn the camera off.

The overexposure was the camera’s decision. I didn’t have time to figure out how to keep the Auto ISO from overcompensating my setting.

Do any of you notice this behavior on the Panasonic GF-1?
