Is there an SLR with no viewfinder blackout?
6 months ago

Hi there, I am a professional photog looking to further a personal project involving long exposures. I would like to track my subject throughout the exposure. Currently, viewfinder blackout does not allow me to maintain visual contact with my subject as I expose for 1 second or longer.

Does anyone know of an SLR that does not have any viewfinder blackout? I would greatly appreciate any recommendations.

Thank you!

You could rent a Leica M. It's not an SLR, of course, but you do get continuous viewing.

An SLR? No, because that's how an SLR works: When not taking an exposure, light comes in through the lens, bounces off some mirrors and out the viewfinder. When taking an exposure, mirror flips up and light goes on to the film/sensor instead, and there's nothing showing in the viewfinder.

What you need is something that has an Electronic Viewfinder that will remain active during the exposure, so you probably need to look at some of the Mirrorless ILCs.

R for reflex
In reply to PhotomuseX, 6 months ago

the reflex refers to the mirror mechanism.

You can have the mirror up, or the sensor. You can't have both at the same time. That's how DSLRs work.

Just put any SLR in liveview. Or buy a mirrorless. Not hard.

No SLR can do this but you can attach a Sight-Finder to any camera, a discussion is going in Sony SLR forum: http://www.dpreview.com/forums/thread/3571427

The gadget is available on amazon as well as B&H

Some sample images from the thread:

Interesting. M4/3s gets close, with live bulb refreshing the screen every 0.5s, but I doubt that's sufficient.

I think the Red Dot Sight, posted above may be the best option.

This sentence
In reply to markkuk, 6 months ago

" It also means that the E-10 has very little shutter noise (no mirror flip), to compensate you can (god forbid) enable a simulated shutter sound (just like a Sony Mavica)."

That sentence made me think... I think I'd have to enable the sound! Quiet shutter is a pleasure, but a shutter with no sound? Would drive me crazy!

Any of the old pellicle mirror cameras, but almost all were film cameras.

Its Canon EOS RT, but it reflects 2/3 (66.66%) of light to OVF & 1/3 (33.33%) to film that results in noise as well as slower shutter speed.

SLTs sensor get 70% of light that served to EVF, only 30% goes to A/F mechanism.

But Canon EOS RT OVF does not blackout

Not any SLR. I just pulled out a D90 out of curiosity, live view goes dark on a long exposure.

Except electronic viewfinder shows zip when sensor is busy recording a long exposure.

The only systems that do what OP wants are those with non-TTL viewfinders.    Get a rangefinder or a TLR.

Actually, Olympus cameras have Live Bulb and Live Time modes which update screen/EVF during exposure, as often as every 0.5 seconds.

To what question?
In reply to tsk1979, 6 months ago

An SLT does not update the EVF during still exposures.  The top-of-the-line A99 doesn't even supply live view updates at 6 FPS continuous -- just replays of the previous exposure (past not present).  You don't get actual updates until you drop down to 3 FPS.  Heck, even a Canon Rebel can do better flapping it's mirror at 4-5 FPS.

I'm not sure about A99 but SLT A77 provides updates with 12 fps, like any other SLR/Ts it blacked out in long exposures

12fps
