not really surprising to me, fuji has been making lenses for hasselbad for years and the hasselbad xpan is manfactured by fujifilm, with the increase in tethered shooting the mirror was slowly becoming obsolete to the actual shooters that use these systems as the typical SLR viewfinder would be to hard to see in some situations.

curved sensor?

the cost benefit is rarely passed on to the consumer otherwise the camera manufactures own brands of lenses would be cheaper than the third party ones
and yes some of us are happy to do some post processing.



unlikely, the whole idea of curved sensors is to reduce diffraction when stopped down and vignetting when wide open



the main problem is etching and coating a curved wafer, i imagine yields would be another factor.

Cheapest Flash with optical Master and HSS capability?

then the cheapest option is to use your camera in manual mode with the metz mounted in hss mode on the lowest power, to trigger an yongnuo yn-560II(or mark III/Iv) in s2 mode (this is important to stop the yongnuo from firing prematurely before the shutter has a chance to open) the yongnuo must be set at max power for this to work (for the longest flash duration 1/200s)

this method works but only suitable for studio work (pro's have been using this hack for years to fire strobes on optical triggers)

the reason why this hack works is the shutter does not open till the light from the first flash has passed thru the lens (hss works by firing a series of flashes in quick succession)

but since you have a cactus v6 why not pick up a a cactus rf60 (its value for money since rf60 also acts as another v6 transceiver and works with pttl as long has you have your metz mounted on top of the v6 mounted on your camera) no more having to do test exposures or manual calculations.

pixel shift on K3 II TEST v canon 6D - PRINT

so let me get this right, you have calibrated your monitor? how and what colour space cause to be honest the canon images look fine, and the first pentax shot looks over cranked (most likely due to the flash and white balance making some colours pop and others subdued) also noise is showing in the dark area of the photo taken at iso 800

I had the non IS version, used it for 12 years and never let me down right upto the day someone stole it.
its one of the reasons why people choose canon, not for the camera's image quality but for the lens

Depth of field?...can we close this argument once and for all

thats more a comparison between jpeg processing than spatial resolution

even a nikon P900 scores well above 2400 lw/ph (above 105mm mark in its zoom range) and thats with a 16mp sensor the size of 1/2.3" (6.2 x 4.6mm)

anyway this thread is so off topic, its time to let it die now.

How would you sell someone on the Pentax Q?

in the cine world we measure lens speed by T-stops (since its not related to depth of field or influenced by crop factor, its purely about the quantity of light we get after the back element)

when in comes to the Q system massive depth of field is a selling point in my book, since its the type of fun camera you would use to document your travels and daily happening

Sigma 10mm vs Samyang 10mm?

anything wider than 12mm your not gonna use the auto focus much if at all (considering the scene would be more your subject than an object so you will be setting the focus for maximum hyperfocal distance), personally i would go the samyang 8mm fisheye for fun value, its build quality and its cost (also defished fisheye images hide aberrations better than rectilinear ones)
