Canon 70-300?
I already have a Sigma 18-250. Would it a good buy to get a Canon 70-300 also? Or the difference between the 250 and 300 would not warrent the big cost of the Canon?

Hello, I just purchased the 6DM2 and want to know if the Sigma DG 150-500 (2008) 1:5-6:3 APO HSM is compatibile. I previously used it on my crop body, but don't want to try it on my full frame without knowing if it's compatible. I found a couple of...

Anyone experience this?? Back button focus on 1DX mk2 with 400mm prime 2.8L IS mk2.Sometimes (probably worse than a permanent fault) it sits there and wont focus. If I turn the manual focus ring to somewhere near the focal length point it picks up ag...
Rattling object inside Canon EF-S lens: Jams or grinds when trying to focus
I have a Canon EF-S 18-135mm lens that has a rather large-sounding object inside that rattles when I rotate the camera. It sometimes catches or grinds when I'm trying to focus, and the autofocus spins and jerks this way and that without being able to...
EF 40mm f/2.8 issue
I use the EF 40mm f/2.8 Canon "pancake" lens on a 6D and have an issue. The lens will appear to "focus" on whatever I select in the focus point in the viewfinder but when I press the shutter, it seems to "prefer" whatever is closest in the viewfinder...
What distance should I use?
At what distance should I set up my 5D Mark IV from the Spyderlenscal? I have read all sorts of varying info. My 70-200L is a bit soft, especially at 200mm. One site says the distance you shoot at, another says 50x the focal length..should I change t...
EF 50MM F/1.8 STM LENS
Considering purchasing this lens to start a Prime collection, it seems very cheap, what will all the ramifications of using this lens on my 70D EF-s camera be?

300mm or maybe not.
A futher little test shows the Sigma 120-300mm f2.8 has serious focus breathing issues. This is from 25 ft.The Canon EF 300mm f/4L IS USM Lens first. Now the Sigma 120-300mm f2.8 at 300mm at the same distance. You can try to decide whether the filt...
EOS T5 - none of the lenses focus
I have the standard T5 kit from Amazon. It worked well for a couple of years, but today I took it out and none of the lenses would focus on anything - near, far, close. Grrrrr. I tried different settings, both on the camera and on the lenses, and not...
AF microadjustment
I finally dialed in the last of my Canon lens today, a 400MM F5.6, and it was the only one that required a major compensation. By itself -8 was needed and with the 1.4X converter in place -1 was correct. Most of my lenses were on with little or no ...
