If you want to buy a Canon lens, you need to shoot a big picture in ultra-high definition, and ask a professional god to recommend it!

If you want to take ultra-high definition photos, you need high-quality lenses. There is no doubt about it. ..... but the choice of lens must adapt to the shooting theme and shooting needs ... If you want to shoot oil painting, the size of the oil painting is still very large, reaching 2 meters. Such a lens is not a good choice. ...

In terms of picture quality, the picture quality of macro lens, especially the sharpness, is absolutely the best ... but the macro lens has a long focal length and is not suitable for oil painting with a 2-meter format.

If you use a short focal length lens, you can shoot the whole oil painting at once, but the short focal length lens has the problem of perspective deformation, which may distort the oil painting and lose the overall effect. ...

So, personally, you have two choices:

1, you can choose a 35mm fixed-focus lens with an aperture of F 1.4 ... The image quality of this lens is absolutely excellent ... The focal length is short and the viewing angle is wide, which should meet your shooting needs.

2. Move the lens along the axis. ..... the biggest advantage of shifting axis lens is that it has no perspective deformation, and can take horizontal and vertical photos ... which should be very meaningful for you to take oil paintings. ...

The above is purely a personal opinion. I'm not sure whether ... is accurate ... for your reference only.

Personal suggestion: You'd better shoot with the lens first and make sure you can meet your needs before making a decision. ...
