lawamainn: When it comes to value for money, this camera is unbeatable! The resolution power alone makes it a winner. And the feature set is pretty awesome as well. I love it!
To which camera are you referring?
malcolma: tony: take a look at the explanation of how Nikon did the self-cancellation in the D800E. I sure it'll be the same for Canon.
Thank you 'malcolma'. I found the item you refer to on page:-http://www.dpreview.com/reviews/nikon-d800-d800e/images/d800e-olpf.jpgIt seems a complicated way of achieving the result. Cameras converted to IR use usually remove the 'hot mirror' and replace with a calculated thickness of plane glass to keep the same optical path length for focussing, etc..Still, I assume Canon/Nikon know the optical business unless the technique is goverened by the need to use standard components where possible.
What exactly is a 'self-cancelling filter' quoted in the introduction? I thought cameras had either an anti-alias filter or not. Does the phrase 'self-cancelling' imply that there is an anti-alias filter plus another which effectively cancels the first?
An explanation would be of interest and welcome.
I have just viewed and enjoyed Parts 1 & 2 of your 1939 photo restorations - the year of my own birth. Particularly, I enjoy the thread of your family's story connecting these widely distributed pictures together just like a gentle soundtrack. It brings them to life and together and much more than otherwise.Very well done and thank you for sharing!
Valant: Anyone any idea what make the double decker bus (DD) in picture Nr. 8 is? Probably Daimler, they launched the first motorised DD in 1898, but it looks like a 1940's British bus. I tend to associate DD's with London and Britain in that era.
Many British DDs were Daimler in the 50s, and Leyland (before they became British Leyland incorporating Morris Austin vehicles).
I tripped over this 'ISOless' issue in some large threads recently and have found your article above to be the source material. It has given me much food for thought and practical experimentation with my Canon 6D. From sensorgen, I find the 6D to be a partial ISOless camera, ISOless from about 3,200 ISO, and have tried some experiments comparing brightened RAWs (in ACR) at 3,200 to those taken at ISO 102,800.
As you state, the noise is just the same but the gain of the ISO 102,800 setting has blown highlights when compared to the 3,200 + brightening. Note, there seems to be a considerable colour difference between the two methods, greatly reduced by also adding extra brightening to the green channel. So my tests continue with the prospect of never increasing ISO past the 3,200 setting unless the DR of the scene is low.
Thank you for the stimulating post. I will have to rethink much on the back of it. Empirical results will be my yardstick but thanks again.
My greatest debt to DPReview is for the cameras you stopped me buying with your in-depth reviews. You have saved me thousands! I am a sucker for the latest new gimmick.With deepest gratitude and best wishes to ALL at DPReview.
So near and yet so far.
Seen this review and another showing live in human hands - it is big.
If it was Full frame, same mount, 5 Fps for RAW AND HDR groups, preferably faster auto focus, and not too much dearer, I would buy it for all my old K-mount lenses.
The only advantage of the APS-C for FF capable lenses would be the smaller size but it isn't. The size is no problem as a user but would also almost do for a FF so the loss is the rest of the usable lens field in a camera whose major selling feature is the ability to mount all Pentax K lenses.
I await a Pentax FF follow-up with great anticipation. The K-01 is pointed right at the appropriate market and proved they are capable of delivering just what is needed, so let's be having it.
I hope this is just a simulation because I don't think they will ever have to make one!
Gold plated, crocodile-skinned, 35mm Leicas may well be 'gilding the lily' but where's the 'lily' here?
