Lens recommendation

513 Views 4 Replies 4 Participants Last post by  tracer bullet
I need a recommendation for a fast lens because I plan on taking some photo's at the gun range, and I need to be able to use the fastest shutter speed I can so I can capture the muzzle flash and the firearm(s) cycling without blur.

I was looking at this lens, but before I spend the money for a new lens, I would like to know what lens you guys think would work the best for what I want to do.

That's a good lens, but keep in mind that the depth of field at 1.8 will be razor thin. What lighting conditions will you be taking the shots? If its outdoors and sunny, you won't need f1.8 to achieve a high shutter speed.
what D said. In fact you might even want to go with the 50mm F1.8 or F1.4 just because you will gain a slight DOF advantage over the 85mm. But even with that, focus is going to be SUPER critical. Personally I would try to keep it above an f4 and just crank the ISO up to 1600. Unless you're trying for a bullet shot, something around 1/1000 should be more than enough to capture what you're looking for.

That definitely crossed my mind about the DOF being so thin. Some of the shots I have envisioned, I want to try and get a behind and off to the right shot, so I can capture the muzzle flash and the brass ejecting. I definitely wouldn't want the rear of the rifle to be in focus and the muzzle out of focus, so that is definitely a concern.

I will most likely be taking the shots outdoors when it's sunny; however, I may try them at an indoor range as well where lighting would be an issue, but mostly outdoors.

I was looking at the 50mm lens as well, but I wasn't sure which would make a better candidate.

If I'm going to shoot at f4, then I may be able to get away with my current 28-135mm f/3.5-5.6 lens. I guess It would be worth a shot (no pun intended) to see what kind of results I can get with that before spending the money for a new one, and if that doesn't work out too well, then I'll probably have to go with the 50mm.

I appreciate the help guys. Thank you.
If you're shooting at an angle, you're going to want to figure out your depth of field that you need to capture. I'd go here: http://www.dofmaster.com/dofjs.html and you may find that you already have a lens that'll do the job if you aren't going to end up at f1.4 or anything. You're going to have to start with aperture to get dof, then decide what shutter speed you need, and lastly figure out the right iso.

I'd also second the 50 1.4, superb lens for only a little $.
