5D II Review
Brief 5D II review from Anantech here for anyone who's interested:
http://www.anandtech.com/digitalcame...oc.aspx?i=3470 5D II looks good, even @ ISO 6400. That said, it's a shame that they didn't put the AF points in more useful locations. So, even though the AF point spread on the D700 is not as good as on the cropped D300, Nikon still seems to have a much more versatile AF system than the 5D II. |

If it does, is it only with the centre point or all points? |

I'm waiting for mine to come... I find this review quite encouraging after I followed another thread on the possibility of the 5DII being far noisier that the 5D because ot its more numerous pixels. I'm looking forward to more in-depth testing while I wait for my camera to arrive (January?) Regards, Marcel |

As the 5D II bodies are being released, there will inevitably be a huge amount of in-depth reviews coming out soon. |

The D700 uses the CAM-3500FX focus system, the D300 the CAM-3500DX. With decent light and a good contrasting subject the D300 focuses OK at f/8 max. Ahum, don't want to burst your bubble, but my D300 focuses even at f/22 in total darkness. It's called the AF assist light? -- Focus |

Focus during movie mode - yes or no? was 5D II Review

I'm looking forward to more in-depth testing while I wait for my camera to arrive (January?) I think this is the calm before the storm. As the 5D II bodies are being released, there will inevitably be a huge amount of in-depth reviews coming out soon. Can anybody confirm that these cameras will actually autofocus *during* a movie take? I can't find the source now but I recall reading that some cinematographer who made clips for Canon or Nikon said "off the record" that his only gripe was that the camera he used wouldn't focus while in movie mode, he had to continually manual focus it. When I look at many of the clips Canon have approved of, there doesn't seem to be much focus going on during the shoots. I know there are mirror types that allow focus during shooting but these would limit low light ability. I'm about to make some decisions regarding HD video capture and the Sony and JVC camcorders are looking extremely price effective compared to DSLRs with movie capabilities. I'm not looking to make feature length movies, just 2 and 3 minute clips to splice into my ProShow presentations. Maybe these initial release models might not live up to the promise? I wasn't impressed with a D90 when I tried it and the D700 is out of the question (for me). Anyone got any constructive information here? |

If it does, is it only with the centre point or all points? If it focuses at all, focusing performance will be significantly reduced with a maximum aperture of f/8, unless the lighting is very bright. If you have any experience using SLRs that focus using split image focusing screens, you'll recall that beyond a certain f/stop (whether because it's due to using a small aperture lens or because the f/stop was reduced using the DOF preview), the split image rapidly becomes extremely dark, even though the surrounding part of the ground glass screen doesn't darken as quickly. The AF sensors use tiny prisms similar to those used to manually focus those old film SLRs. I believe that all of the AF sensors are used, not just the central AF sensor. While I don't think your specific questions are answered, this DPR thread has a wealth of AF sensor information, especially in the replies posted by Marianne Oelund. Note that there are slightly more than 40 replies, and each web page (in Flat, not Threaded view) displays a maximum of 20 replies. http://forums.dpreview.com/forums/re...9687488&page=1 |

If it focuses at all, focusing performance will be significantly reduced with a maximum aperture of f/8, unless the lighting is very bright. Total and utter nonsense! My D200 focuses perfectly at f/8 in low light using the 500/4 Nikkor and 2x TC. The D200 will lose AF focus ability at f/9 as I found out when testing the 105/2.8 VR and 2x TC. This is the closest focus setting on that combo. That said, my D3 doesn't have any problems with it nor should the D700. The reason why it appears to be total and utter nonsense is that you're unable to tell the difference between total failure and reduced focusing performance. It's understandable though, since you use the 500/4 for close snapshots of your mutt taking a leak and not for distant BIF action shots. Attach your test charts to a swinging pendulum and let us know how well the D200 focuses and tracks the target with the 2x TC and 500/f:4 on it, preferably illuminated by a single flickering candle. You don't have to add an ND filter. |
