I am curious how to calibrate the Canon Canon EF180mm f3.5L Macro USM AutoFocus Telephoto using the Datacolor Spyder Lenscal? The instructions say to multiply the mm by 25 to get the length to set the Lenscal away from the lens in order to perform t...
Hi I currently have a 80d but I wil be upgrading to a FF(5d mark iv) by the end of the year. I'm in the process of purchasing a new lens but I am having a hard time trying to decide between the Canon 24-70mm f4l or ther Tamron 24-70mm f2.8 G2. The ca...
In June I will be taking a long road trip and hope to check out a few national parks like Arches, Zion, and Monument Valley. Right now, I have only the 24-70 2.8 ii. I was thinking I should add a 70-200 to the toolkit. Any thought on which lens is a ...
Recently got a Canon refurb EFs 24mm pancake lens. But now I'm not sure if it's acting up on me or not. While taking some photos of the sign below the autofocus acted strangely. I composed the shot and focused using the back button and the image wen...
Hi all, When shooting from distance (not very far - around 10 meters back) the Canon 24-70 II lens seems to be very blurry and bad quality. Can I get some advice on whether this is a common issue and if there's a resolution to solve this? I wouldn't ...
In a few months my daughter will be playing again with an indoor soccer league and the facility where they play most of their games is a horribly lit dome (mixed mercury vapor and high pressure sodium bulbs with a few very bright areas and lots of di...
Odds on how successful this'll be? With or without sigma dock? Lens worked great on Canon 6d.
This feels like the dumbest question ever but I just got a 50mm ef1.8 STM lens for my Canon T6i. Very excited to try it out but I'm not quite sure I'm attaching it correctly? My kit lenses have a white guide dot that I align with the white dot on t...
The filter mounting threads broke on the end of my 75-300mm III lens. All I need is a new plastic ring that screws onto the end of the lens. I am unable to use my lens cap or lens hood
So I have the 16-35 mark 1, it took a spill this summer. It still works fine, the glass and everything is intact, but the threds to screw filters in got dented in a little. I can still get filters on there, but they don't screw on very well. I contac...
Greetings Gents,While I was recently considering picking up a 100mm 2.8L for Macro (shooting bugs), I decided that I'd much rather take some wildlife photography given the the time of year. Started researching and after 12 videos and a bunch of readi...
Hello to the wise camera people of this time. I bought a canon ef-s 18-135 IS USM last Christman and for the most part the camera and lense have worked perfectly, however, when I got the camera out of the closet recently, the lense was practicaly dea...
Recently I was changing the lens. When I removed the auto focus 18-55 zoom lens a part fell out of the lens. It is metal and has copper contacts on it. I'm not sure where it belongs or why it fell out. Anyone had a similar problem?
So I dropped my kit lens and as I was turning the zoom ring I heard clacking.I noticed while zooming toward 18mm that the back element was "loose." I opened up the lens from the back and noticed that the back element was actually connected to other e...
