Pag and CTJohn, very nice shots!
I shot some video this evening with my 6D, of fireflies with my Voigtlander 58 f/1.4. Looks nice enough on the camera's screen, not uploaded it yet.
Carl, tell me about the Voigtlander. I have heard some say that other than the lack of AF it is actually one of the best options in the 50mm range.
I personally love it. The metal body looks and feels identical to Zeiss. I would say the bokeh is not as smooth as the Canon 50 f/1.2, or the 135L...but the color is superior at least to the 135L. The bokeh is creamy smooth if there are not extreme highlights in it. The contrast is similar to the 135 (which is saying something, because you know how contrasty the 135 is). The sharpness is extreme on the 6D. On my 50D, sharpness was still extreme, but you could kind of make out barely some lateral CA...very minute, of course...but even it seems absent on the 6D. There is still some slight longitudinal, or "bokeh" fringing...but it's not very strong...depending on just how extreme the contrast is at the transition of dark to light edges of subject matter (and this is at wider apertures). Not unusual for fast primes of any focal length, I suppose. By about f/2.8, even this is completely gone.
I decided I wanted it, after looking at photozone.de's test of it. According to their charts (they don't say so outright), its resolution is beyond all other 50mm f/1.4 primes they have tested, including both Canons, the Nikons, even the Zeiss...at least at wider aperture than f/4 or f/5.6. Certainly a couple of them tie or beat it, at around f/5.6. I'm sure there are other sites which might not be so kind to it, but my sample sure seems to be up to photozone's.
It had essentially no vignetting at f/1.4 on the crop camera, and barely a moderate amount on the 6D. Perhaps 1.5 stops near the wide f/f border, maybe close to 2 at the corner? I don't know...I forget what their test showed. At the extreme corners on the 6D, there is a bit of noticeable aberration, likely coma (not uncommon for an f/1.4 lens on a full frame). Through most of the frame it is just about perfect, in my opinion. And like the above, when you close the aperture down some, the coma goes away. This is at the extreme corners. And this is from the perspective of trying to use it for astrophotography, or otherwise looking at a file at 100% at the corner, to decide what it's doing...certainly at 8x10 print size or something, I doubt you could see any aberration.
The main thing I don't like, is that it's a manual lens. If you are shooting at a closed down aperture, then the light meter is never going to be accurate. Sure the finder image is darker (sometimes looks darker than it should, say at f/4). But the main problem is innacurate exposure. It's not really a problem at f/2 or faster, though...since it's nearly wide open. Of course there are no clicks between f/1.4 and f/2, so the ring can move a bit if you touch it, when setting it somewhere in between. And of course the camera only always shows "f/1.4", even when closed to f/16. The focus ring, feels like heaven...perfect rubber teeth, perfect amount of back-pressure.
The "dandelion" chip in the Fotodiox (Nikon-to-Canon) adapter I use, works like a dream. It gave accurate
focus confirmation at the much reviled side AF point of the 6D, in a dark room when I tried it a night or two ago. But there's also a caveat I must mention with this adaptor. It needed "tightening" with a jeweler's screwdriver, because at first the lens was loose inside it. I damaged the tip of the screwdriver in the tightening process...but fortunately it was a cheap one...which is probably why it was too weak to hold up in the first place, haha!
If I could ever get my DVR tv shows watched (we keep getting free weekends of the prime channels!), and some house cleaning done, in between wasting my time online, I could get some pics edited!
I'd also really like to post some video clips I shot with it just last night, of fireflies amongst some deer at my pond...on the 6D. But I don't have a youtube account. Should I create one, or try another site?
What I really need is a comfortable chair cushion for use at the desktop. I am not really more than like 20lbs overweight, but I have an occasional ache of my tendons around my hips, from sitting (doc said it's genetic). I want to try one of those $100 gel cushions, but I don't want to spend the money. Any thoughts? My cousin mentioned the $20 cushion at bed bath and beyond, but the online comments on it, looks like it goes flat after a few days...as I have found all cushions seem to do. For the last couple of years, I just sit on an orthopedic "bean bag" type cushion...it hurts and feels a bit too firm...but it never goes flat. I paid like $40 for a first generation "memory foam" cushion about 8 years ago. It lasted about 4 months before it was totally blown out...but it wasn't really thick enough, only like an inch. A new computer chair would help, but the cushion in it would just feel the same as this old one after a few weeks.
