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...
Another which is better. Look at these. Now a 200% crop of each. Both shots are made with the Canon EF 300mm f/4L IS USM Lens. One shot has the IS on and a UV filter. The other has no filter and IS turned off. Worse case to best case? No right or...
HI there, I am sort of new to photograph and I was looking at some lenses, I am wanting to shoot photos next year of my trips whenever I am out hunting and was wondering if a 70-200MM would be useful to have? I am wanting to possibly take photos of d...
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...
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...
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...
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...
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?
Curious if anyone here has any experience with this unit, I am interested in astrophotograhy, although where I live there will not be any astounding milky way shots I would like to at least experiment with the genre.I have looked at several trackers ...
I do mainly bird photography and like the versitiliy of this lens. However having focus problems. Lens does beautiful landscapes but when trying to focus on moving object not so good, even with a high shutter speed. Anyone else using this lens a...
Hi,I made two photos on a Canon 80D using aa. Canon EP 100 Macro lens andb. Canon EP-S 55-250 lensBoth times I focused on 100mm. I don´t see any difference. One should be cropped? Any explanation? Thanks
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...
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...
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 ...
I have a EF 100-400 f 4.5-5.6 l series lens. It is suddenly having a hard time communicating with the camera. I get an error message that says clean the contacts, which I have done. The problem persists. I am in Panama, and there is an authorized Can...
