Originally posted by Mattox I learnt a lot from the workshop really. I found that some basic fundamentals are essential in landscape photography (well all photography really). There at essential in camera settings that you need to apply to raw prior to shooting. These I should probably discuss in a separate topic. Within the group however there was another pentaxians who shot with a ks and a 15mm. Looking over our shots in raw up against the big bad FF of canon, Nikon and Sony, the difference in DR, resolution, noise and especially sharpness was significant. After this experience the move to FF is a must. If Pentax don't show something soon and something that is going to compare especially to the 810 of Nikon the move over to another brand is going to have to happen to me. The true landscape photographer need to keep his shots so precise all round and all the the Lightroom in the world won't change the final results if these are not respected.
I'd assume the problem is more in that you are comparing a five year old camera to more modern ones. There are many excellent K3 landscape images to be found online, and when paired with a good lens the AA filterless K3/K3 II deliver results so sharp any disadvantage against a D810 becomes a purely theoretical point - measurable in the lab but irrelevant in real life. For all practical purposes (showing on the web, printing biiig) the sharpness is excellent. Declaring the move to FF as a 'must' is simply an excuse, I'd assume that you would not experience a general palpable improvement in your photography when switching to a FF.
"The true landscape photographer need to keep his shots so precise all round ...", that sounds like the workshop was more about turning participants into technical snobs than what actually matters in landscape photography: light, composition, and being in the right place at the right time.
Originally posted by redcat I find the same when shooting wedding with another Canon 5D guy, I retouch all the photos from both cameras (mine is K3) and create the final album and I see the difference is significant ! the Canon FF has better DR, noise and color tone (ex : skin tone, blue, orange), I hate to admit that my newly bought K3 is not up to the Canon FF level, hope the new Pentax FF will be on shelf soon !
Wait a second there - I'm not surprised that the FF has better noise performance, colours etc., but DR? Based on reviews and the experiences of a lot of the online community Canon trails behind the competition in DR, even when comparing their FF offerings to others' APS-C offerings. The K3 has been tested to have a better dynamic range than the 5D Mk III, at least up to ISO800 or so
