Often, I have been requested by picture lovers, whether the Cannon EOS-1D MK IV or the EOS 7D is a better electronic camera and which body system do I choose. This is not an simple query to response. First, a little backdrop would be to be able. I have been using Cannon devices for about 25 decades. I began out with the Cannon EOS-1 in 1989. When Cannon first presented their D30 photographic electronic camera in 2000, I chew the topic and purchased the body system. It was SO costly but I desired to research with the new technological innovation. Since then I have used every DSLR Cannon has presented, significant up to the 1D MK IV and 7D systems, which I currently own.
First, let us get the significant specifications out of the way. The 1D MK IV has a 45-point AF program such as 39 cross-type factors, a new AI Servo II AF concentrate monitoring program with enhanced criteria along with 10 fps ongoing capturing. It has an APS-H scaled 16.1 Mega-pixel CMOS Indicator, Double DIGIC 4 Picture Processor chips, an ISO variety of 100 - 12800 (up to 102400 in H3 mode).
The 7D has an APS-C dimension 18 megapixel CMOS sensor and Double DIGIC 4 Picture Processor chips, with ISO variety from 100 - 12800 and rates of speed of up to 8 fps. It comes with the new, all cross-type 19-point AF program with enhanced AI Servo II AF topic monitoring and user-selectable AF place choice ways. It also has an Brilliant Viewfinder, an entirely new technological innovation, provides roughly 100% protection and shows user-selected AF ways as well as a identify metering group and on need collections lines.
Both set of specifications look amazing but how do they execute in actual life environment? I add the Cannon BG-E7 hold to the 7D to provide it a 1D like experience and have taken both electronic cameras out on many picture launches under severe surroundings. A few difficulties are dealt with out in my thoughts concerning the EOS 1D Mk IV:
#1 - MK IV surpasses the 7D arms down under severe varying climate circumstances because of its all climate closing. I was saturated from go to toe within a astrology in the Sea of Cortez, in difficult ocean, a few decades ago but the 1D MK IV with the 70-200mm f/2.8 L IS II kept operating without any hassle.
