Canon NEVER Mentioned A High-Res Camera In Interview

High-Resolution Sensor

A few days ago I featured a news originally reported by Canon Rumors. It was about an interview that DC.Watch (translated) had with some Canon representatives. Well, there was an error in the interpretation of the machine translated text.

The Canon reps never mentioned the possibility of a high-resolution camera. The error originated from the fact that the colors assigned to question and answer were not correct. In other words, the Google translator marked the question with the color of the answer. In reporting the interview, the question and the answer were confused, and the question was erroneously reported as the answer.

Thanks to DicaHub, I can clarify this. Dicahub was so kind to make his own translation of the interview and to send it to me:

Q: And this is only my personal impression, but after releasing of EF 100mm F2.8L IS USM Macro, I feel the resolution performance of EF lenses has been level-up remarkably, are there any differences compared before, about such the design level to the target (but not consider to view the pixel size based on print result), the design concept and so on?

Iwamoto: I can’t answer detailed, but as the pixel-count of the digital cameras are becoming more and more, the target level of the lens performace are definitely coming up gradually.

Q: How many pixel-count (or how small pixel pitch) to be resolved sufficiently are recent L lenses designed to be performed?

Shimada: The lenses are products with very long life after launching, so we are considering and developing with the target level that they can be performed with the future cameras.

Q: We can get really high definition detail if we take pictures with Sony A7R mounted recent L lenses via mount adapter. At this time the model with highest pixel count is 22MP EOS 5D Mark III, but regrettable, EOS 5D Mark III can’t get the greatness from L lenses.

(Following paragraph is green color, but black in Google translation. The mistake originated from here.)

I opposite to increase pixel count to higher, but if there are high performance lenses matched to such pixel count (or pixel pitch), I also have some hope to see the true power of the resolution. There are launching of lenses with good image quality at the edges, so I expect the launching of higher pixel model of EOS.

But in that cases are there something to be missed by increasing resolution power of the lenses? I’ve heard it is difficult to get proper tones when resolution is increased…

Iwamoto: High quality lenses what we target are aimed to get high resolution and high contrast both. But if too focus to high resolution, the lenses will be larger and expensive, so considering such balance, we design to target such resolution performance matched to the era.

So, there is no official mention of a high-resolution camera by Canon.

Thanks again to DicaHub for helping clarify this.

Canon EOS 7D Discontinued On Amazon US


Another sign that something new is coming from Canon, and hopefully soon.

Amazon US lists the Canon EOS 7D as discontinued. The EOS 7D is still available from third party sellers.

The replacement for the 7D is expected to be announced shortly before Photokina 2014.
