You CAN use it on a phone, but I would highly recommend using it or any other tether control with a tablet or laptop.  Trying to do it o a phone denies you the benefit of a much bigger display at ...

I tried with the Opteka and it works.  It was an issue with an AF setting exclusive to the live view screen. I bought the tablet and DSLR Controller so that I wouldn't have to use the camera's ...

It's certainly very useful, especially for macro if you can't afford an automated rail.

I may have fixed the live view zoom issue. I was just shooting a small computer screw from my studio macro rig and found I couldn't get the optical zoom button to work, even though I was using my ...

The thing is that you'd think it's not really a lens issue, since you're not trying to get the lens to do anything.  You're just asking the camera to do an electronic zoom of the live image it's ...

I just got a reply back from the author of DSLR Controller. He says the problem is due to erroneous information reported back by the camera, probably because of the non-Canon, manual lens. Working ...

We'll just have to see what Chainfire (the developer) has to say.  He's slow to answer, but gives good information.  He told me how to insert pauses between exposures so that I didn't cook my good ...

Having to activate the live view zoom on the camera first to get it to work on the tablet isn't a terrible chore, it's just unexpected and slightly annoying. I can live with it until or unless ...

Update: After looking at a couple of older posts on the Android developers' forum, I started looking at camera settings regarding auto-focus. Obviously this lens doesn't auto-focus. However I ...

I use DSLR Controller.  It's great, especially for focus stacking. The "5x" icon is inactive.  It's there, but touching it doesn't do anything. I posted a question about it on the DSLR Controller ...

I can zoom in with the tablet when I use my Tokina 100mm macro, so it is possible.  I didn't try it on the LED today.  I'll try that tomorrow if I get a chance.  Of course having the bigger screen ...

Thanks, that's kind of what I thought. It was still hard to focus, but it was much easier. One thing that helped, was to turn the brightness on the tablet way up. A problem that I ran into was not ...

Well, here are some results with the lens hood, adjustable aperture, and lever follow focus: These guy were not close.

There's no reason for me to "research" a facially nonsensical premise. My time would be (and is) better spent researching ways to get more from my two 500mm mirror lenses.

And the topic of the thread has WHAT to do with photography? Like the "Matthew Brady" character in "Inherit the Wind", you're sidestepping the question...

Creationists tell me exactly the same thing. And again, what does this have to do with photography?

All of the budget mirrors are T-mount, so you can mount them on anything for which there's an adapter.  I have in fact used it on the T4i.  I'm working on the Opteka because it's the bigger ...

I wouldn't know.  No harm in contacting them and asking.

"Disrespect"?  You make it sound more like religion.  Ironically, I'm watching "Inherit the Wind" right now.  You might want to remind yourself that science is about empiricism, not received wisdom. ...

I've been in Berea or Rocky River since '86, with a brief interlude in Fremont. Just about the only photography resources here of any real utility are Dodd Camera and Pixel Connection out in Avon.  ...
