1D Mark IV - High ISO Images

[Axel Hildebrandt]

The page takes a while to load: http://unwire.hk/2009/12/18/canon_1d...so_video_test/

Images at ISO 6400 look remarkably clean. I don't know if in-camera noise reduction is enabled and if they are resized full frame images or crops, though.

Axel, Thanks for sharing.

In case you don't read Chinese, the highest ISOs recommended by that site are:

• ISO 6400 for full HD monitor display
• ISO 12800 for prints of A3+ size
• ISO 25600 for website use
• ISO 51200 for small photos in newspapers/magazines

Thank you, Desmond! This information is very useful for many people here who are not entirely fluent in Chinese. :)

Desmond, can you confirm that most images are 50% crops?

[Alfred Forns]

Worth the wait for loading !!! Never trust these samples but they sure look good !!

....thanks Desmond !!!

Painfully slow!!!

These looks like JPEGs with standard in-camera noise reduction, and then reduced to 50% not much you can tell... I wonder why Canon has withhold releasing more MKIV samples until now, I remember Artie mentioned he had some nice samples.

Al, I hope you are right in thinking it will ship soon. I can't wait!

12,800 looks pretty good too. But I'd be ecstatic with a totally usable 3200.

It states on that page the stuffed-pig shots are 33% crop and those of the color pencils 100%. How much then they reduced the pics for posting, it doesn't say.

It's extremely slow here, too. So slow that I gave up waiting :)

Are the above images prodution or preproduction copies? Canon HK sent out a press release stating a December 23rd availability for Hong Kong.

No idea, it's probably a good idea to wait to judge the image quality until the new bodies are available. Here it is not even clear if in-camera NR was enabled or not.

DPR has some very good high ISO images in the 1D forum
