I have a Tamron 17-35. It's 2.8 at the wide end but goes down to around 4.5 at the long end. It's a decent lens, not spectacular but pretty good. Heavy and well built ,and can be used with full frame cams.

Yes Ian, you are correct, that's what I intended, that the features are more crafted towards Photographers than anyone else. As far as the sensor topic, I removed that from my post, perhaps before you finished your reply. I'm a Video person (so far), that's why I opt for the 7D. JS |

If the larger sensor allows for more light then in theory the 5dmk2 would allow for narrower apertures at equal exposures. In other words longer DOF without losing light. Sometimes i hate the shallow DOF on wedding work. I find it annoying when the focus shifts over and back from bride to groom at random times. Ideally both should be in focus and beyond and in front of that should be where the focus falls off. So that would place the 5dmk2 firmly in front of the 7d in some lowlight locations.

I think here in Pal land the 5d/7d choice is a little simpler. The lack of 25p is a huge problem for us. I really don't want to give up full-frame, but if you do any production work in Pal countries, the 7d makes much more sense. |

Oh yes i see what you mean. Thats good to know.
Im like yourself Josh, for me its a no brainer. 25p all the way. |

Of course, the 7D is no 1/3" camcorder, and it has a newer generation sensor and noise reduction algorithm. I haven't used one yet, but I'd guess that the noise won't be all that different from the 5D2. It might measure differently in the lab, but I doubt that there will be much real-world difference.

This assumes the 7D hasn't made a great leap in terms of sensor technology / processing - too early to say at this stage but there are pixel peepers on some forums giving 7D low iso images (the few available) a pretty rough going over. From what I've seen (from the few samples online) the 5Dm2 does enjoy a low iso advantage, as it should. The 7D seems to hold it's own surprisingly well in terms of high iso. |

There's been lots of testing of the 7D noise vs the 5d2 noise... what has so far been determined is that the 5D2 has less noise but the noise seems to show a pattern (banding)
ever so slightly... The noise on the 7D is very slightly more than the 5D2 but they aren't seeing any pattern to the noise... So the consensus is, 7D has slightly more noise, but its " Quality Noise "... some are comparing the 7D noise to film grain. and of course the randomized noise of the 7D is easier to take care of in post edits... |

I've always noticed that film grain was slightly more pleasent to look at, most of the time, than digital. I never thought about any science behind it though. Very interesting. |

Liam I wasnt speaking about iso at all.
I was talking about the size of the sensor allowing more light fall onto it therefor at equal iso one camera would allow for a better exposure than the other. What else is the whole point of emphasis being on sensor size. I was simply speculating that if it would be possible to have deeper dof with a well exposed 5d shot than a well exposed 7d shot this would be a good thing. Johsh reminded me that sensor size increasing reduces dof so both cancel each other out. Obviously iso needs to come into play next. |

Ger, the exposure would be exactly the same on both cameras. The smaller sensor merely crops the image.
