I played with one briefly at a trade show; while perhaps large; it feels much lighter than the 18-55 when on the camera. Handle pretty well. Can't comment on optical quality.
Quote:Perspective control??
You should compare it to the Canon EF 35mm f2 or EF 35mm f2 IS USM, as it is a 23 x 1.5 = ~35mm 1.4 x 1.5 = f2.1 FF equivalent.. Of course it is less heavy and has less blur wide open than an f.4 FF lens.
It is not smaller or lighter than the 35mm f2 lenses, but you do have a smaller and lighter combo with the camera body.
Quote:Apples and oranges.Huh? Why is a 6D with 35mm f2 lens not "valid" and a 70D with 24mm f1.4 lens "valid"?
A valid comparison would be the EOS 70D + EF 24mm f/1.4L - even price-wise
Quote:Otherwise I could just argue with the Leica M + Summilux 35mm f/1.4 - at smaller dimensions and smaller weight than a full format Canon.Yes, one can. Why could one not compare a Leica M + 35mm f2 to a Fuji X series with 23mm f1.4? Or a Leica M to a Canon 6D with 35mm f2 lens? All valid comparisons.
Quote:I could also throw in the Voigtlander 35mm f/1.2 which has obviously an more pronounced bokeh.You should read my post again, it seems you miss the point (the point being that a 35mm f2 lens on FF does the same thing, and that a 35mm f2 lens is less big and heavy than a 35mm f1.4 lens, which appears to be important to Diertdeb).
It is a question of "good enough". Dietrdeb has obviously found his sweet spot.
Quote:Perspective control??Actually it is not at all like a FF with a 35mm f2. The exit elements are much larger than a 35mm f2 to accomidate the light transfer of a F1.4. Also I have shot with a Canon 35mm f2. It is a crappy lens. A comparison to the 24mm f 1.4 is more akin. I agree with Klaus this is apples to oranges.

Quote:Actually it is not at all like a FF with a 35mm f2. The exit elements are much larger than a 35mm f2 to accomidate the light transfer of a F1.4.You do not understand lens design then. It is a 23mm lens, that is why the elements are larger for one. But also, compare a Canon 50mm f1.4 and a Sigma f1.4, they show things are more complicated than that.
Quote:Also I have shot with a Canon 35mm f2. It is a crappy lens.I have shot with the Canon 35mm f2 lens. It is not a crappy lens, it actually is quite a nice lens. And the new Canon 35mm f2 IS USM is a very good lens.
Quote: A comparison to the 24mm f 1.4 is more akin.Of course it is not, a 24mm on FF gives a much wider view than a 23mm on APS-C.
Quote:I agree with Klaus this is apples to oranges.You are mixing up bokeh with blur. The blur will be similar. Maybe the bokeh too, but bokeh is the character of blur, not the quantity.
You are forgetting that although the bokeh might resemble that of an f2 lens,
Quote:in actual shooting conditions it allows the exposure control of a 1.4. For street photography this often makes a huge difference.You are not using equivalent ISO settings. f1.4 does not say how much light gets captured (a smaller sensor captures less light than a bigger sensor), it just describes the focal length/aperture ratio. Exposure also depends on exposure duration, and (which you are forgetting) signal amplification. On APS-C with smaller sensels on smaller sensors, the signal gets amplified more. If you use similar amplification (equivalent ISO settings) you get similar results, also for street photography.
Quote:I think that you are over thinking all of this. And yes the 35mm is a crappy lens.You must be aware that you can set any ISO/ASA value on your meter, right? So, if you want things to be similar, set the meter to equivalent ISO settings for each of the camera bodies. Of course, it is very seldom necessary to get the same exposure duration. But if you have to, use equivalent ISO settings.
All I know is that if I take my meter outside and read for a fire hydrant, and set my camera and shoot, both an FF and an APSC, a view camera or any other camera will make the same exposure at the same ISO.
Quote:The rest of what you are saying is just ridiculous as each digital camera performs differently using high ISO settings, and it has alot to do with pixel density. The Fuji I have for example performs better at ISO 6400 than the Canon 5D II I used to shoot with.That is why mentioned that sensor technology is a totally different discussion.
Quote:And I am sure that both lenses collect light at a "similar" angle of view, but the Canon 35mm f2 has a sinificantly smaller exit element than this lens.It is a 23mm lens. Of course it has different element sizes. Especially since one lens is designed for an SLR with much bigger flange distance, and the other is designed for your mirror less X series Fuji camera.
Quote:The Canon 24mm 1.4 is closer to the size of this one.What are you talking about?
Seriously, if you are that insecure with your Canon, why do you bother reading blogs about the Fuji.
Quote:The Canon set up you are describing has it's advantages I am sure, but size is not one of them.And? Did I state the Canon + 35mm f2 would have a size advantage? No, I stated the opposite.
Quote: And if you are so "brilliant" at lens design and know so much about what is required, then you should be making cameras instead of trying to tear down the designs of other people to try and make yourself feel better all of the time.What are you talking about (again...)?? I do not remember tearing down any lens design in this thread. I merely pointed out that you comparing the big and heavy Canon 35mm f1.4 to the 23mm f1.4 from Fuji was a bit of a wonky comparison, and that a better comparison would be to compare it with a 35mm f2 lens. And I explained WHY that would be a better comparison.
Quote:, then you have never shot with the Canon 35mm 1.4, and definitely not with a Fuji 23mm 1.4,I never said it was the best lens or that no comparable lens could not be better. I said that it is quite a good lens yes.
Quote:either of which blows that crappy f2 out of the water!!!It is not crappy. And I am sure both lenses you mention perform better in areas.
Quote:I have shot with all three. As for the 35 is usm I have no idea, because now that I shoot with the Fuji system I have no intention of going back to Canon.That is why it is nice that Klaus tested it and provided us with examples. We can see it is a good lens, without even having to won it first! B)
Quote:ESPECIALLY since I have NEVER used it...HINT HINT HINT! Sometimes intellectual people spend more time thinking than doing! Just because I don't take the time to bore everyone with mathimatical equasions doesn't mean I don't know how to take a photo! BTW if you want to enter the 35mm IS USM into this discussion, then shouldn't we note that it's size and weight are BIGGER than the Fuji 23mm.You seem to be the insecure one. I did not type one negative word about the Fuji lens. I merely pointed out that you complaining about the weight of the 35mm f1.4 in comparison to the Fuji 23mm f1.4 was a bit crooked, as the fuji is equivalent to the smaller and lighter Canon EF 35mm f2 or Canon EF 35mm f2 IS USM.
Quote:One suggestion; if you claim a lens is good or crappy perhaps you should describe how it is good or crappy. This might help orient the discussion around technical merit rather than name calling. There are many parameters which define a lens. Now for my 2ct on the 35f2 (non is). I have never own this lens but have never been 'wooed' by images I've seen taken with this lens. It seems to have decent resolution but seems to be a bit dull and I personally find the bokeh distracting.Good suggestion, about describing it not being crappy.
Btw blur does depend on more than just aperture (or equivalent aperture). Lens design can change not only the bokeh but also the amount of blur given a fixed focal length/aperture/format. There is an interesting zeiss paper that discuss how the design can impact the transition around CoC.
