I'm looking to get a moderate wide angle for a Canon 6D. The only other lens I'd have is a 50mm f/1.4 ZE, which is a bit long indoors for me. I also have a 100mm macro non-IS, but I would have to sell it to fund the wide angle. My main focus for this lens will be video work, typically not much closer than 1-2m from the lens. Obviously I'm not necessarily looking for peak optical quality since I got the 50 1.4 (and the lens will often be stopped down anyway), but I'm looking for a lens that will give me the most flexibility in terms its behavior in different situations. The main "weaknesses" of the 50 1.4 are close up performance, wide open dreaminess, and sometimes nervous bokeh. I was initially looking at the 35mm f/2 ZE, which optically seems to be a nice counterpoint to the 50, however, I feel like its focal length is a little too close. Another option I have found at this price range (~$550) is the 25mm f/2.8 ZF with a Leitax adapter, but it seems to have similar weaknesses to the 50 especially in terms of close up performance. At what distance does the close up performance of the lens noticeably begin to affect image quality? Also, is this mostly due to field curvature, or are there other notable sources of degeneration?
The 35mm will be wide enough for me indoors, but it is kind of borderline as it's still a little longer than I'd like. I feel like the 25mm would be a better choice despite its shortcomings because the focal length is simply better suited for my purposes. However, I'm wondering if there are perhaps alternatives around this focal length that might perform more similarly to the 35mm. I've also looked at the 25mm f/2 and 28mm f/2, but they are about $300 more expensive used, which is basically half the cost of the macro lens I'm saving for. I've only mentioned Zeiss lenses (rather than Canon, etc.) because I like them for video work, but I'm definitely open to other suggestions.
Also, I'm thinking about getting an EG-S focus screen, but I've heard mixed opinions on how much it actually helps with these lenses especially because of the focus shift of the 50 1.4, for example, when stopped down. Also, since the 50 is rather hazy wide open, which can somewhat mask misfocusing, I'm wondering how much benefit this would actually have especially since the other lenses I'm considering won't have quite as shallow a depth of field. I mostly use Live View, but it's not great for when I'm shooting handheld.
I really appreciate any insight!
