I have a H2/P30+ and a Canon 5D.
I "hate" working with the P30+. It is big, it is slow,
it is very easy to miss focus because it is so narrow and only one focus point,
it is hard on battery, it is heavy to lug around with 5 lenses, it has big files that eat up disk space etc.
I love working with the 5D. It is everything I miss in the H2/P30+.
Most of the time I shoot with the P30+. Some times I get
frustrated and grab the 5D and shoot with a smile.
BUT when I get back on the computer and look at the result I
ALWAYS love the P30 result and "hate" the 5D result.
It is not only about the resolution, even if that also is a big difference.
It is everything about the picture - resolution, colors, transitions, shadows, bokeh,
highlights, skin, clarity, and how easy it is to retouch.
It is like the 5D is 10 mm "thick" and the P30+ 10 cm.
Many talk about a film like feeling. Yes, it is like film looking at the P30+,
and digital looking at the 5D.
P30+ is smooth and 5D is hard and ugly in comparison.
You can read all about the technical numbers, but you have to see it to understand it.
And I had a MkII and switched to 5D because I liked those files better.
Everyday I get frustrated working with the P30+, I try to remind my self that I will feel much better when I get back on the computer and see the results.
I also would love to see a Canon with P30+ ( or other similar MFDB ) quality.
But I do not think it will happen soon.
