Really High ISO Noise
I'm contemplating picking up either a T2i or a 7D, but I'm
wondering about a couple of things. First, has anybody seen any comparisons of pics from these two 18 meg sensors? Just wondering how the cheaper T2i stacks up against the semi-pro 7D in the area of overall quality. Second, as the main reason I'm interested in either is the high ISO range, I'm wondering how these cams perform in the 12,800 ISO stratosphere... Are the pics useable? Would they be too grainy if blown up to 16 x 20? I'd appreciate any thoughts you might have. Take Care, Dudley |

Take Care, Dudley You can check samples at http://www.dpreview.com/ It will be grainy or blotchy, depending on how you tune the noise reduction. Clear photos may require some extra effort - brighter lens, external illumination, or stacking. -- I will not see posts or email from Google because I must filter them as spam |

Just my opinion, as an amateur. |

And neither one can produce usable images at ISO 12,800 except for very small prints or web shots. |

Just my opinion, as an amateur. Thanks, Charles, that's about what I expected. But, even 3200 would give me an extra stop over the XSi... Also, for less active subjects, I'm thinking it would be possible to set the shot up using LiveView and 12800 and then step down to a quieter ISO for the actual shot. Although, that would entail a lot of switching in and out of Live View. Still, I don't like the way my XSi meters the flash in LiveView, so that's what I'm doing now. Thanks for the info; it gives me something to think about. Take Care, Dudley |

Thanks for the info; it gives me something to think about. Something else to consider is the handling and manipulation (buttons and dials and joysticks) of the T2i versus the 7D. I have only used the 7D, so cannot make a comparison. Perhaps another can chime in here and help out? |
