and there is no real answer to this question as in the Canon camera line, image stabilization (IS) is a feature of the lens and not the camera body.

Your notion that a faster lens is inherently better IQ than a lens with about 1 stop slower max aperture is simply not correct.  It is true that many of the highest resolving lenses are f2.8 or...

How do you define "best"? For a wild ass guess I will assume you mean best possible image quality without regard for cost. mid range zoom for either FF or crop: Canon 24-70 f2.8 II L WA  zoom for...

I can tell you have never done tilt adjustments as a split prism is useless for this application.  I know, I tried using a Ec-B split screen for a few years with a 1DmkII and Canon 24 TSE I.  The...

You have this backwards.  Using the RRS lever clamp, which has no adjustments for different sized plates, there are a few plates out there which will not be held tightly.  This incompatibility with...

I would never consider a 5DI for Tilt shift shooting, whereas the 6D and 5DII are both fine. I can tell you have never done tilt with a 35mm camera; one cannot accurately establish fine adjustment...

Yes, I was going to suggest an external monitor, they come with all sorts of features, especially those designed for video use.  I use a Small HD DP6, which is a 5.6" monitor with HD resolution,...

With the 6D the AF points are clearly outside of the rule of thirds grid intersection http://www.dpreview.com/reviews/canon-eos-6d/6 Scrool down to the section entitled: Viewfinder information You...

First, before purchasing anything, try Live View, press the Start/Stop to initiate Live View (LV).  Press the info button several times to see optional display info.  The third press should yield a...

No, The exposure sensor is in the petaprism area, thus the mirror has to be down for an exposure reading.  Normally a half press of the shutter button will trigger an exposure reading reflecting...

The recommendations from Canon have always using 50X focal length or further for calibrating micro adjust.  Thus a 50mm lens would use a target 50X 50mm = 2.5m, about 8 ft. Apparently you have...

with a 24-105 f4at 24 mm you will easily see optical vignetting (gradually darkened corners) at f4 with no filter at all! And this is through the viewfinder, not the LCD.  Thus any filter will...

2 years ago a very carefully controlled blind test was done on FM alternative lens forum trying to identify a Zeiss lens from a Canon lens of comparable focal length.  Not which was better, but...

I realize English is not your native language, but your questions are rather general and rather vague. I hope these references help. The TSE 90 will require more tilt than any other Canon TSE...

I was addressing the concern of the OP: that upon review of RAW capture, the images aren't as detailed as with Live View 10X. This is a general question that comes up for all Canon dSLR shooters,...

When reviewing RAW shots after they have been taken, the LCD uses a small thumbnail size JEPG.  When zooming in to magnify, it will not be sharp, regardless of the JPEG settings, the small...

You already have the possibility to contrast detect AF with an f8 lens combination.  In different Canon models CD AF has a different name but often is called Live View "Live" AF.  Yes, at F8 the...

This is my understanding too.  Perhaps under the conditions the OP typically uses the lens, the degree of focus shift is not so apparent.  However tje softening of the image can be misinterpreted...

OK so you have ruled out focus shift.  To calibrate max sharpness of AF I simply compare Live View 10X magnified manual focus against AF using a target which shows up sharpness differences easily. ...

I do not have thae 50/1.2 so can only comment in general.  Very wide aperture lenses, such as the 50/1.2 are very prone to focus shift.  The focus is done wide open, and the lens is stopped down...
