All I can say is that it is about time it came out … indeed it is long overdue given the old Ds is now nearly 4 years old. The old Canon 1DS III is looking a little long in the tooth now in comparison to Nikon and other full-frame cameras – 21megapixels as compared to 24.5megapixels in the Nikon DX3. Of course high pixel counts are overrated, but for instance the DX3 is capable of recording relatively low-noise images at far higher ISO ratings than the 1DS3.
So where is it ? Of course there is a great deal of resistance to jumping ship and moving to Nikon from Canon because of the large investment in lenses that many of us have made. But sooner or later people are going to ditch Canon in favour of Nikon, so Canon needs to bring out the 1DS IV pretty sharpish.
Of course I am only interested because the new camera will cause the prices of second hand 1Ds IIIs to drop through the floor and I’ll be able to pick one up for a reasonable price to replace my 1Ds I 🙂
