fuzzybud Posted December 1, 2005 Share Posted December 1, 2005 If a certain photo situation dictates a shutter priorty setting of 500 f/1.8. But the VR lens widest opening is 3.5. How would I take advantage of the 3 or 4 stops more I have to work with because of the VR? Does the lens compensate and adjust automatically? Thanks for your reply.

SCL Posted December 1, 2005 Share Posted December 1, 2005 3.5 is 3.5. Your shutter speed will either adjust downward or your camera simply won't take the picture. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted December 1, 2005 Share Posted December 1, 2005 Well, in this case you'd probably get underexposed pics. VR helps you by reducing camera shake. That's all it does. This means that you can take a 200 mm lens and take reasonably sharp hand-held pics at 1/100 s or even lower. It does improve the sharpness of pictures in these situations tremendously. However, VR doesn't stop motion so if that's why you need a 1/500 s exposure time, VR won't help. It will help hand-hold at a slower speed so you get more depth of field.

erickpro Posted December 1, 2005 Share Posted December 1, 2005 The VR lens will only redude vibrations from a handheld camera. That is the only thing the VR lens does. Vibration Reduction. Link to comment Share on other sites More sharing options...
fuzzybud Posted December 1, 2005 Author Share Posted December 1, 2005 Thanks for your help. I don't know what I was thinking. VR would allow me to shoot at a slower speed and a smaller f/stop. Thx Brendan Link to comment Share on other sites More sharing options...
erickpro Posted December 1, 2005 Share Posted December 1, 2005 I meant, reduce. Link to comment Share on other sites More sharing options...
Ed_Ingold Posted December 1, 2005 Share Posted December 1, 2005 VR lenses provide 2 or 3 "stops" advantage over non-VR lenses, meaning the VR will steady the image at slower shutter speeds. In "photo speak", stops can mean either aperture or shutter speed because changing them in concert produces the same exposure - called the "reciprocity law."

rick_beets Posted December 1, 2005 Share Posted December 1, 2005 Vibration reduction, in theory! I sold my 80-200mm AFD lens, bought the 70-200mm AFD-VR. No noticeable difference really, nice lens though! I had a couple of situations with the 80-200mm where I needed to shoot in low light, had to shoot at slow speeds and just tossed out the bad ones, I had hoped the VR would be a giant leap forward here, but I don't really think it gives me the same sharp images at 3 stops slower. It does focus quicker and works well with SB800. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted December 1, 2005 Share Posted December 1, 2005 Well, the 70-200 certainly gives me its money's worth of VR, in fact I'm often astonished by how well it works. Link to comment Share on other sites More sharing options...
