I'm hoping third-party brands (other than Zeiss) eventually bring more compact (slower) XF mount lenses to market. The new Road Map does not indicate Fujifilm is thinking about this.
Fuji updated their lens roadmap

Hmmm...I tried it and prefer it to the Fuji 35.
I don't use lens hoods on most modern lenses. A UV filter is sufficient to protect the front element, and modern coatings are flare-resistant enough by their own merit.
The bokeh is "defined", but not something I would say bad. I thought the lens compares favorably to the Zeiss 35mm f2 ZM, which also has rather odd OOF rendering.

On reflection, awful is much too strong a word. Nevertheless, I was disappointed in the Touit. The Fuji, in my view, has a better-balanced set of optical and operational characteristics and for me the longitudinal chromatic aberration and relatively high geometric distortion were deal-killers.
That color bokeh, along with high sharpness, does make the pictures look a bit like they were shot with certain (highly-regarded) 1960s Takumars (though with much less pleasing blur circles), and in that sense the Touit has real character. In the end, it comes down to preference.
I will say that the Touit looks spectacular in black and white. So much so that I wonder if that's what the Zeiss designers had in mind.

I agree. At it's original price point there is very little reason to choose it over the XF35 if you don't have a burning desire to have something blue painted on the lens.
At the current, reduced price ($900 for the two-lens kit), however, I felt that it was a good enough lens to recommend to a friend looking to build her first mirrorless system.

The Sigma DN series would be nice additions. And the Sigma 18-35/1.8 ...

why do you think the thrid party folks are staying away from fuji?

Hard to read the Japanese tea leaves on this - it's Sigma, Tokina, Cosina, and Tamron who won't play. I suspect some sort of "arrangement" among the Japanese mfgs. Notice Samyang, Zeiss, and SLR Magic are right in there - Zeiss with AF, too!
Also, one might suggest that Fuji doesn't really need the 3rd party people as much as say, Sony. The Cosina 21/1.8 and 35/1.2 both work great on Fuji with adapters, but it would be pretty awesome if they made some native super-speed lenses like they do for m4/3... How about an x-mount 23/.95 ?

3rd party lenses...
I think this is a case of looking for the simplest answer.
In this case. Fuji is making top quality lenses at extremely competitive prices.
How does a Cosina or Sigma Compete?
3rd parties traditionally make entry level or economy options.

Probably because the current market share is too low. Sigma does m4/3 which includes two brands.
Another reason is third-party brands could assume most consumers want larger aperture lenses anyway... which Fujifilm has covered.
There is more opportunity with SONY who seems to have a lens diversity deficit.

The sigma DN series goes for around 190 (19, 30 and 60 all f2.8). They apsc mount for e and m43.. Given the flange to sensor distance difference for x mount vs m43 or e mount, I suspect some redesign would be needed. Their apsc and ff dslr lenses would be huge on the Fuji cameras...
Sigma is a small company.. Most likely they need to watch how thin they are spread. I agree w/ Andy in that unlike Sony, Fuji has a great lens roadmap that covers the needs of both the amateur and serious photographer w/ a very competitive price range.
So, those third party makers need to fill in holes in the lens lineup or come in under what Fuji is selling for.

Now that Fuji has such an awesome lens roadmap, I need a purchase decision-making roadmap to go with it!
Still waiting for the eventual incorporation of the organic sensor technology into a new X-Pro design.

Why?
The new sensors are claimed to have 12 dB better dynamic range and 20% better sensitivity. But it's not at all clear that that's versus a Sony sensor, and if it is, what generation.
I'll look forward to organic sensors if and when they are demonstrated to offer photographically meaningful improvements over the CMOS sensors that are available in the same time frame.

I don't think so, not from e to x mount anyway. Some Rokinon and Zeiss lenses are exactly the same but with a "built in" adapter to compensate for flange difference, no doubt at minimal extra expense. I would say the issue is to do with licensing rather than anything else.
I do hope Sigma and Voigtlander start making lenses for x mount, even if it's just modifying the mounts of their existing lineup.

Very confused
Pretty well any 4/3 lens (except T/S lenses) will be designed to cover the 4/3 sensor with a diagonal about 21.6mm. This is the diameter of the circle within which vignetting needs to be acceptable, i.e. practically insignificant. The diagonal of the APSC sensor is about 28.3mm, about 30% more. Thus a 4/3 lens will generally need a complete upsizing to work with APSC, not just a rework of the flange distance/mount. To avoid this, the third-party makers would have to start from an APSC lens designed for some other mount.
This would be for a manual focus/exposure lens. To AF and AE on the X system, they would also either have to license or reverse engineer the Fuji electronics (this latter might involve patent violations). These factors, added to the relatively small market for this lens system, plus the competitive lenses also available or on the way from Fuji, as already mentioned, must be somewhat discouraging, but might eventually come true.
AFAIK, the Samsung lenses that fit x-mount are manual lenses, while Zeiss is not competing on price.

It doesn't matter how good a Sony sensor might be if it doesn't or cannot find its way into a Fuji X mount body.
I just assumed that the performance upgrade was with regard to the current Toshiba sensors that Fuji uses.

I happen to have a E mount to m43 adapter that I bought for grins to use on my Nex 5n. The difference could not have been any greater than about 1/8th of an inch. This can be hidden in the mount change itself. The x mount would require a new lens barrel plus the electronic ribbon cable for the mount contacts to be lengthen. Then there is the issue of the number of electrical contacts and which each one is used for (which ones for voltage, ground, data and control bus) or that the voltage and signal levels are compatible w/o some changes to circuit design. The same was probably done for Sony and m43 as well in terms of the electrical and programming requirements.
Since the m43 and 43 are open standards, it was pretty easy for them to build lenses for that system. Sony's Nex lens lineup in terms of serious quality was until recently weak especially in terms of good primes. Sigma definitely saw a market there that was worth the expense.
Then there are the issues that JohnL mentioned which are related to Fuji requirements to control the AF and AE mechanisms. Fuji also puts lens specific correction information into their lenses which is expected to be read out. Does Fuji even allow third party lenses that they do not recognize full AF/AE control (remember they worked w/ Zeiss one on one to get them working, while Samyung/Rikonon are pure mechanical hook ups - go thru shoot w/o lens mechanism)?. It could be Fuji is saying pay the license of u are programmed out for all we know.
Hope that clarifies where I was going.

Sigma probably started w/ the E mount design for the Nex apsc camera first (or at least designed the lens to have a image circle big enough for apsc) and then added the m43 since they have mount exchange service for m43 to e mount and vice versa. According to the writeup in sigma rumors sight, after the mount is changed, the af mechanism is re calibrated for the new camera system.

Samyang just announced a 50mm 1.5 for X mount. There's an opening. Not everyone is ready to drop $1k on a 56/1.2.... If it's as good as the 12/2 they will sell a few. I have a CV Nokton 50/1.5 on a properly shimmed adapter, so I won't need one.
I still think it's some sort of Japanese corporate politics.

errm. I have been told by a few different Fujifilm reps that it's a Sony sensor.

Could you elaborate on properly shimmed? How can it matter if you focus via live view?
Do you mean shimmed for infinity to to align the focus scale?
Just curious. I use a Hawks close focus adapter and it seems just fine for the CV1.5/50mm for the few times I use it.
Thanks for the reply 🙂
