EOS R6 lens recommendations for video & anamorphic lens compatibility

[MariannK]

Hello! I’ve just bought a Canon EOS R6 camera (only body) and I want to buy a lens which is good for videos too. Also, I am thinking to buy an anamorphic lens, any recommendation please? And how can I attach an anamorphic lens to the camera? (budget is under $1000) Many thanks for the help.

Welcome to the Community. 

Anamotphic cinema lenses are far beyond your budget by a factor of 30x and up. Even though there are EF mount cinema lenses by Canon, I don’t recommend using one on any consumer products.  The lenses tend to have significantly higher current draw than the cameras can handle.

What a coincidence, last Saturday, I was on a full day shoot in Independence Kansas for the annual Neewollah Festival and the other guy on the shoot with me was the video photographer. He had an R8 and a Sirui 35mm anamorphic lens. Other than the gimbal mount I noticed no real difference between what he was doing and me. Personally I have no experience with one.

I was strictly speaking about Canon full frame, cinema lenses. The Siri lenses are not full frame lenses.  They’re Super35 lenses. They do not have autofocus, either.

Hi Mariann and welcome to the forum:
If you want a lens for video and photography, it is helpful to know what kinds of subjects you want to shoot, as that has a significant impact on the focal range required.  Since we know you want to shoot videos, perhaps we can start with that...  

Given the advice from my colleague as regards the cost of an anamorphic lens, we need to look for a solution for you that will work. 

For video of people, vlogging, and wide angle work, and considering your budget of $1,000, I would suggest the RF 14-35L IS f/4 lens.  It has fabulous optics, image stabilization, takes standard circular filters without adapters and is solidly built.  I have one and it works beautifully: it focuses silently, with virtually no focus breathing and is extremely sharp, especially for the massive focal range.

You can get one from the Canon Refurb shop for $999, so just on budget.  Refurb lenes may be overstock, new but open box, demo or show units, but are 'good as new' and come with the Canon warranty for a year.

Alternatively, if you want a longer focal range, then the excellent RF 24-105 f/4 is a great general-purpose unit, with IS, silent motor but slightly over your $1,000 budget at $1,169:

Those lenses may be good but they offer nothing comparable to an anamorphic lens and that was the question.

With respect Ernie, we seem to be reading the post differently.  The question was made up of several parts:
1.  "I want to buy a lens which is good for videos too" (the last word suggests a hybrid use with stills)
2.  "Also, I am thinking to buy an anamorphic lens, any recommendation please?"
3.  "And how can I attach an anamorphic lens to the camera?"
With the condition: "(budget is under $1000)"

Questions 2 and 3, about whether an anamorphic lens would fit, and the impracticality of getting one from a purely economical point of view was dealt with effectively by our other colleagues.  That left a solution for question 1 that fitted within the limits of budget, as indicated. 
Thus to provide the OP with a solution, I was addressing the first question, and in that respect my answer was valid and to the point, as it is priced to respect the budget, which is critical, and is a great (albeit non-anamorphic) lens for both applications.

On the contrary what you said has nothing to do with the OP getting an anamorphic lens and that was the part I was responding to. Sometimes the budget doesn't work with what is available. That is something for the OP has to work with not me.

"He had an R8 and a Sirui 35mm anamorphic lens." "Personally I have no experience with one."

I believe that summed up what advice I could give don't you?
