It would seem a mirror and a pentaprism introduce an additional six to ~eight or more lens/air interfaces, which may degrade image quality somewhat—but the image that is transferred to the actual Sensor-array is not affected!

I would admit there are some obvious advantages to a mirrorless camera system, but there are potentially some drawbacks as well: restricted view of actuality (view-screen display limitations), and rear-displays that may be difficult to observe in all conditions.

The new improved more polite version of myself would simply call that a “highly imaginative” post.

The mirror-less myth persists when it comes to sharpness and could not be further from the truth. In reality, a tilt-shift lens on a dlsr, especially for corner to corner sharpness is unbeatable.

Thaz why I use my T/S lenses on a Sony ... cuz I’ve just never bought into myths about myths, as promulgated by typical sorryazzed “online experts” who believe that a sensor can be affected by the user interface. Maybe you’d attempt to explain how a sensor might be influenced by the presence, or absence, of a mirror and a prism ? Give it a try. I’m here mainly for the entertainment value anywho !

This is pretty funny actually. Bogus but funny.

I MEANT to include that the ONLY degradation to the image would be in the viewfinder light-path due to interfaces and perhaps prism internal reflections, not the in light-path to the sensor array.

By the time I saw the mistake it was too late to edit.

My fault.

Let's call out another mistake: the EVF - Electronic View Finder - can be used for both image composition and image review. So, you're idea of difficult to see situations for the rear view finder is removed / not applicable for MILC by doing the image review via the EVF.

And the EVF has nowhere near the image quality delivered by mirror/prism designs, does it? And likely never will. So “what-you-see” is not 100 percent of “what-is-actual”.

Other than your biased opinion, what makes you think the EVF is inferior? Anything actual, such as usage?

BTW: if you find image review from an rear-screen LCD or a camera view finder is relevant, I have some property in Florida I'd like to talk to you about, a real deal.

Were you not stating not-so-long-ago that the image-view on mirrorless cameras (rear screen and maybe (?) VF) was so very useful as both a preview/focus device as well as a white balance and exposure-spectrum option?

(BTW, I am budgeting for a Canon Full Frame mirrorless right now. Currently in the range of EOS RP or equivalent.

Good that I used my new improved somewhat less acerbic reply mode ;-)

I just addressed this in another thread. First of all electronic viewfinders have come a long way and not only can they rival an optical viewfinder in quality but they also offer some clear advantages. I can see scenes through my Z7’s viewfinder that would be too dark with my D500. I’ve used the viewfinder on the Z7 when shooting 30 second exposures though a 10 stop ND filter and not only can I see and focus but I actually see what the exposure looks like.

The Hasselblad of the film era was an SLR. A Zeiss 40mm Distagon wide angle lenses was available for the camera. Nonetheless Hasselblad made and sold at the same time the SWC which was fitted with a 38mm Zeiss Biogon. It was a lot of money back then. Why buy a whole new camera without SLR viewing just to use that one fixed lens. And the answer is distortion -- as in not there in the 38mm Biogon but very much there in the 40mm Distagon.

I can personally back that up. In the late 70s, I purchased a 38mm Biogon F4.5 (scavenged/salvaged from a SWC Hasselblad) that was mounted, shutter and all, onto a 4x5 Sinar lens board. It was installed in a Sinar F front standard, and had a hand grip attached to the bottom and a 21mm Zeiss viewfinder on the top center of the standard. The grip was equipped with a cable shutter release. The idea behind the camera was that the lens was wide enough to cover a 6x6 up to a 6x9 format, making it very suitable for shooting with 120/220 roll film backs. The extension and volume anamorphic distortion was non-existent. The 21mm viewfinder was a Schneider intended for its 21mm Leica lens, but was good enough for all but the fussiest composing.

Years later I found a Contax rangefinder with a 21mm Biogon F2.8 and the matching Zeiss viewfinder which had the exact same qualities as it's bigger brother.

The store was FotoCare, on 5th Ave at the corner of 21st St if memory serves me right. They were right in the middle of the photo district in NYC, where many photographers had their studios in the cheaply rented/leased loft spaces.

This old article from the Washington Post describes the Biogon's "magical" properties. It is my understanding that the biogon lens formula was first introduced by Zeiss in 1934, and it is a symmetrical design (the element groups in front of the entrance pupil are of similar size and position as the rear element groups). Many wide/ultra wide lenses are reversed telephotos. I don't understand lens design, but I do understand the benefits in this case.
