Camera - Canon EOS 7D - Review Comments


The Canon EOS 7D is a new DSLR in the semi pro market segment intended to fight the highly popular (and capable) Nikon's D300s. It is not clear if it is intended to replace the EOS 50D, but certainly should be a gap filler between the Rebel T1i (EOS 500D) and the EOS 5D-mark 2. When released some eyes raised, asking about the logic of the model number. It is a single digit model (As the EOS 5D), but using a smaller APS-C sensor, rather then a full frame sensor - The real issue here. The EOS 7D is using the largest pixel count of any APS-C sensor today - 18Mp. This means that pixel size is smaller then any other DSLR and light sensitivity is lower. Canon claims higher efficiency of the sensor, so, the expected high ISO noise will be low.

Potential customers waited to the first pro grade review to arrive. It is here from DPREVIEW.

Looking at the review, makes you feel something is missing. DPREVIEW, as usual, is doing a great job, analyzing each camera in depth. The conclusions are what bothering. They are minimal and do not referring to the review details and the provided test images.
.
The "PROS" is stating "Class-leading detail and resolution at base ISO". This statement is immediately raising some questions:
.
1. When do we start to consider DSLR for their base ISO only. Many compact cameras, cheaper and smaller, are yielding good image quality at their base ISO (Usually 100). DSLR users are putting money to be able to use high ISO without (almost any) image quality considerations. There is no conclusion, PROS or CONS about the high ISO performance.
.
2. Looking at the high ISO images (and magnified parts), clearly showing a lower performance compared with the Nikon's D300s. No related conclusion.
.
Bottom line is simple. No magic here. Higher resolution with the same sensor size is reducing the high ISO image quality. Readers may have their own thoughts about this review.

  1. This is a good camera for the price. It is simple to use and takes clear, crisp pictures. Also, the battery life is good. And the price makes it affordable to take good pictures.
