Good reason to move to Iceland or Sweden.

noflashplease: A photographer sneaks up behind a police officer during a traffic stop on a dark and stormy night. The photographer is illuminated by a flash of lighting and the officer sees what looks like a hunter's tripod and a firearm pointed at him. Yes, hunters do use tripods to steady rifles. The important aspect of the law is that the officer had a legitimate belief that his life was threatened. Police officers are expected to act pro-actively to defend themselves and public, unlike civilians. The officer was telling the truth as to what he believed at the time of the accident. That's all that matters under criminal law. The officer wasn't criminally negligent. As far as the civil standard of negligence, the photographer is probably partially liable. My guess is that the whole matter will be settled out of court and a lawyer will get 1/3 of the settlement.

He didn't sneak up. The officer knew he was there.

Bas Bridges: I'm fathoming in what angle of view a tripod can look like any gun/shotgun/assault rifle, but there is none.

The only possibility is that the three legs of the tripod could make it look like a minigun.

See now, the photographer should have known that, right?

So the cop immediately whips out his gun and shoots the guy. He had time to pull his gun aim and fire. In the same time he could have ducked down and yelled "What are you doing over there," while drawing his gun. In the Army I was taught to seek cover first, because I couldn't fight back if I was dead.

I'm certain there are more than a few who misread the title to this interesting piece, and wondered what Fuji had engineered into the X-E3. Screwdrivers? Ratchet wrenches? :)

The Creative Suite is for graphic designers and those that work with film or 3D.

In reply to:

anticipation_of: Who is the customer for a 21mm 3.5? Is the appeal just that it's smaller than Zeiss's 21mm 2.8?

@dansclic: 20mm on a full frame camera is a super wide lens, whereas on microfourthirds its a normal lens. If one desires a zoom in this range, say a Canon 16-35, one is spending $2000 and the lens won't fit in a pocket. The 20mm Skopar is ultimately portable. Cheers,

Possibly. The Skopar models have almost always been small.....and slow. Like f/4 plus or minus half a stop. Which I prefer for travel, or just wondering around a new city and wondering why I didn't bring a 20mm with me.

anticipation_of: That 110/2.5 sounds nice, though. 1:1 reproduction from a comfy 14" away, fast(ish) aperture, and (if as advertised) negligible chromatic aberration. Sounds good to me!

If anything like previous apo-lanthars, I'd love to have one. Would like to know what it will cost.

babart: Unfortunately, it seems strange one would need the Canon or Nikon mount to mate to a Sony alpha. That means if you own a Sony you have to buy a Canon model Laowa to get the shift. Meaning one can't use the Laowa as 12mm without buying a Canon to Sony E adapter. Why not a shift adapter for the Sony E to Sony E? Or did I miss something in the text?

Oh for God's sake. This entire discussion was about one lens and converters/adapters for that lens.

It's entirely about the Laowa 12mm.

meanwhile: If you read the rest of the responses you'll see why it's not doable. I was suggesting a modified shift TC to accept the Laowa 12 in Sony E mount to use on the Sony E mount. It seems, however, that a longer flange distance for the 12 mm lens is needed. Read the rest and it's explained. Ad nauseum :).

Jens, it would not work completely. I wouldn't need any tilt so would use a comparatively inexpensive shift adapter, Canon to FX. One may be able to get 10mm of shift in the vertical direction, but that lowers to about 7 or 8 mm in the horizontal, for obvious reasons. Which is about the max that I've experienced with other full-frame lenses and simple shift adapters, and even then it's best to stay a mm away from the max.

The 12mm Laowa in Canon mount would not be a waste of money, since I could use that lens on my Sony a7. But also, it would give 17mm shift on the APS-C Fuji (using a simple shift adapter WITHOUT the Sony shift adapter), which could be most helpful when shooting architecture in crowded spaces, mainly 19th century homes. It just so happens I have a Zhongyi turbo in Canon FE to Fuji X so I can use the shift lenses I own on the Fuji and get the full field of view. Which would mount the Laowa 12 without any other adapter.

I understand about the need for the long flange distance (Nikon and Canon mounts) for the TC shift adapter for Sony E.

What I meant about a hollow tube SHIFT adapter, without any TC, would be to use the Laowa 12 in Canon mount with my Fuji X APS-C. There are shift adapters Canon to Fuji X on the market. I carry the Fuji X-T2 as backup when shooting architecture. Sorry if I didn't make myself clear.

Jens, Anticipation: Well, the problem then is the same for Canon and Nikon users.....if they want the shift capability they have to buy a Sony Alpha body. I don't see the reasoning there at all. So I'm suspecting that both of you are correct, in that the adapter was made for Sony alpha users, but that there is a problem with the TC needing a longer flange length lens. As for hollow shift adapters, these would only work with APS-C mirrorless cameras. That said, however, since I shoot architecture, next time I just have $1300 burning a hole in my pocket.......I also shoot Fuji. And I'd love the 12mm for my Sony a7. Let's see, where can I get that 1300....

Jens, I did think about that very situation. However the adapter has glass elements that could be arranged to accommodate the shorter flange distance of the Laowa 12mm? Maybe not. Of course, the MC11 is very useful, but it's something else to carry to just use one lens......a great lens though.

There are already several shift adapter for using full-frame wide angle lenses on APS-C sensors. These work well if the prime lens is a good one without much distortion. However, these arrangements are often limited in the degree of shift due to the vignetting of the prime lens. Laowa's TC plus shift, resulting in a 17mm shift lens is a decided improvement. I believe Canon still makes a 17mm tilt/shift lens, but the cost is much higher than this Laowa arrangement.

In reply to:

MightyMike: I have the 12mm, I don't have the shift converter because I don't have a mirrorless camera however I found it to be just as effective to perform the perspective correction in post processing, maybe even better so long as you take your composition into account when taking the original photo.

MightyMike: Mike CH is right about the post-processing engendering distortion. I went to a mirrorless Sony alpha for architectural photography just for that reason. I have two shift lens, a PK 28 and a Rok 24 for interiors. The results are noticeably better than using post-processing. Too, one gets the image one composes, rather than guessing where the image will crop in PP. Nice to hear from you, bbartrug.

I have a 90/2.8 from Tamron. I suggested the f/4 as it would keep the size smallish and who uses a macro at f/2.8 anyway? :)
