There are both advantages and disadvantages to EVFs. The very best ones with high-resolution and high-refresh rates are actually quite suitable for most uses when well-implemented. The main disadvantages are: Lag: There is a short lag between action happening in front of the camera and what you see. Dynamic-Range: EVFs are small LCD screens and have ...

These are different designs, developed at different times. Forty years have gone between each was initially launched as the A-mount was simply acquired from Minolta which had by then fused into Konica-Minolta. The A-mount introduces AF which worked by Phase-Detection and hence lenses for that mount are designed to focus that way. Over the years, they were ...

Short answer: the difference is in an SLR the mirror flips up to take a photo, whereas the SLT employs a semi-transparent mirror so that the mirror never has to move. Now to your questions: 1) How does a DSLR do continuous focusing (AI servo/AFC)? Does it literally flip the mirror up, take the shot, put the mirror down, refocuses and repeat? That's ...

Almost definitely, yes it will leave an artifact in the photo. As you get closer to image sensor, defects and damage in the optical path become more visible and prominent. People worry about minor scratches on the front element of their lenses a lot, but defects on the rear elements of lenses typically cause more visible artifacts. Small dust particles or ...

Your understanding is accurate. There are variations but the most significant difference is what you see in the viewfinder. This answer goes into all the details. The other significant difference is that the PDAF sensors are available during exposure and video-capture. This lets an SLT camera measure AF while an image is being recorded and then it adjusts ...

The mechanical shutter is still between the translucent mirror and the sensor when the camera is turned off. Even if you select the option to use electronic first curtain with mechanical second curtain, which leaves the shutter open just as many cameras do to use Live View or record video, it doesn't leave the sensor unprotected when the camera is turned off....

I would like to add that unlike a traditional DSLR, the mirror in an SLT is not essentual to the operation of the camera. It can be removed in a few seconds and carefully stored in many small compact flash card cases. The camera will operate without a complaint in manual mode. The contrast based manual focus assist will still function. The preview in ...

Just my opinion, but it's not worth the possible damage you could do for half a stop. I don't think you'd break the mirror, but it's apparently at least partially made of plastic and has coatings on it. And those you might damage. You could also affect focus alignment. Just because you can do it doesn't mean you should. This Youtube video demonstrates ...

I own a Sony A77 SLT camera. I am an 'avid' photographer. As well as well composed and static shots I enjoy pushing the camera to its limits in various ways including situations where correct timing of shutter release is critical. Overall I am happy with the tradeoffs that come from the EVF system. One factor that biases me is that I have been waiting for ...

SLT is the designation of sony cameras employing a pellicle mirror, an electronic viewfinder as well as a phase-detection autofocus system. The pellicle mirror causes about one-third of an F-stop's worth of light to get lost to the AF system. This is of course something you don't want, but the gain is a phase detection even when recording movies. The EVF ...

I made a quick-n-dirty test of rear LCD display lag myself. My friend came over with his Casio EX-F1 compact camera, which can record a video at 1200 fps. We shot a video of the Olympus SP-550 rear lcd panel at 300 fps and then slowed the result down to 1 fps. On the slowed video a one second represents 0,00333 second in real life. I had a Metz flash ...

Yes, the SLT a35 has a focus motor in the body. You can use legacy A-mount lenses, such as Minolta lenses since 1986, and non-SAM (Smooth Autofocus Motor) and non-SSM (Super Sonic wave Motor) lenses on the SLT a35.

Use Photographic Solutions Eclipse fluid and their swabs and use 2 drops of fluid on each side of the swab. Place swab on sensor's right side and sweep it over the sensor like a broom and reverse it from left to right when you reach the left side and do not lift it off the sensor. Always use a new swab each time you complete the cycle. The proper size ...

You covered most of the advantages that SLT cameras enjoy over DSLRs, but there are a few other differences that give the traditional DSLR an advantage as well. With an SLT camera, 100% of the light entering the light box never reaches the sensor. In brighter conditions this loss is fairly minimal, but in very low light conditions it can mean the difference ...

I found something about Sony SLT A77's viewfinder. It still repeats what @Itai said about varying refresh rates in different lightning conditions, but what I found interesting was what they said about lag in good light. It is hardly noticeable. A quote below (bolding done by me): When not in continuous shooting mode, viewfinder responsiveness is a function ...
