It kinda reminds me of the paintings that are made by splashing colours to canvas and presenting it as big art. Then people try to see something in those "paintings", too afraid to say it´s rubbish in order not to be called ignorants.
Well, these pitures are just the same. Rubbish. And I truly believe there are segments of photography, where it´s all about composition and camera qualities do not matter (e.g. B&W architecture). But this photographer chose the wrong segment and made bad pictures.

Marc dbr: Next year Canon will make a comeback with 3 cameras in the top 3 spots!
1) Canon full frame mirrorless,
2) Canon 5DsR II
3) Canon 7D III

Beware folks!

Well the 6D Mk II didn´t exactly prove that a successor must be significantly better than the predecessor.

I have been to Positano in september. The number of people was enormous and it spoiled the impression of a beautiful town a bit. Everybody was photographing, although only few with tripod, I have seen a couple of drones as well. So yes, it is a problem just like in many european cities like Venice or Dubrovnik and I understand the are trying to limit it a bit, although commercial photographers are only a tiny share of all photographers.

du four: Itβ€˜s easy to see what will happen. Using a tripod will be regarded as proof for β€žprofessionalβ€œ photography. A reason not to visit Positano.

The same applies to Antelope canyon in the US. Is it a reason not to go there?

Richard Murdey: "The larger sensor (and hence lower crop factor) of the G1 X III means its F4.5-9.0 equivalent range isn't as different from the F3.8-7.5 equivalent of the Mark II as the actual F-numbers make it appear."

It's still true that the net change is a loss though, and that the net equivalence is the same as the Sony RX100, too. So it will be interesting to see how this shakes down in the real world: do you want a bigger sensor with a slower lens? The camera gets bigger and what you get in return?

Of course, the RX100 is much smaller. But after handling the RX100 I think this camera is too small for a man with regular sized hand; I hat troubles handling it and pushing the tiny buttons comfortably, there wasnt enough space to put my thumb. So basically for comfortable handling I require a slightly bigger camera, so in my opinion a bigger size than he RX100 is a plus, not a disadvantage.
In my opinion the G1X III could be the perfect travel camera. If it wasnt so dman expensive.

Re: "The camera gets bigger and what you get in return?"
In comparison with the predecessor the camera is smaller/lighter, despite having larger sensor and despite gaining built-in EVF (a must for this class).
Given the specs, the weight of only 399g is a small marvel. The closest you get in mirrorless world is Sony a6300 with tiny kit zoom 16-50mm (itself bit slower) weighing 520g.

In reply to:

Father Bouvier: Not a bad lens, good resolution and contrast, flare not that bad, but it's a slow lens, and that limits its usefulness. I think most people will choose 56/1.2 because it's a lot more useful.

While I basically agree that f2 is not very fast for a short telephoto/portrait lens, in Fuji lens lineup it makes sense. First it matches the other f2 primes, making a nice trio (23/2, 35/2, 50/2), second for those wanting a really fast lens there is the 56/1,2, so there was no need to make the 50mm faster.
However for a 50mm prime f1,8 is standard, so Fuji could have doe it f1,8, the distance from 56mm would still be kept.

In reply to:

deep7: Why are most of these taken at ISO 400? All grainy (typical for dpreview-processings, sadly) and not very nice when you zoom in to look at the sharpness, yet some have super-high shutter speeds. A wasted opportunity

Yes, exactly my thoughts. ISO400 on a sunny day, no point having such high sensitivity (having shutter speed of 1/8000s in some shots). Either Carey set the ISO to fixed 400 (which would not be very wise and I doubt Carey did this), or the camera itself chose this sensitivity (which means not very clever auto exposure).
EDIT: Carey explained it in the meantime.

AshMills: Wish I could get my head around DX crop equivalence arithmetic - my simple brain can imagine FF and 2xcrop but I struggle with 1.5 crop. 122mm equivalent lenses dont help! :-)

Yes, 80mm can be calculated by head, 80+40. But try this with 56mm lens or 55-230mm, not that easy. And also the opposite way: if you want to get an equivalent of FF on APSC, you have to divide by 1,5, not easy at all. From this point of view M4/3 is easier. Fortunately I learned most of the focal lengths by memory, so I can tell right away that 16mm equals to 24mm, 56mm to 85mm etc.

iudex: Can somebody explain me why this lens is so big and heavy? I have a 100mm f2,8 macro lens, so 20mm longer FL, also weather-sealed, also 1:1 reproduction, it´s a DSLR lens for fullframe, but it´s only 340g. So this APSC-only mirrorless lens weighs more than double the weight, 120% more to be precise. What is wrong?

neverendinglight: 100mm lens is 100mm lens, no matter what camera you mount it on, crop factor of the camera sensor is irrelevant. It´s always a ratio of pupil diameter and focal length so an f2,8 lens with 100mm has to be bigger than 80mm f2,8 lens. And I mentioned the fact that my macro is FF was just to stress it has to be bigger than APSC lens, however I use it on APSC, so equivalent FL is 150mm.

Stephan: I do not doubt there will be individuals like you that will buy this lens. But you have to admit that you are really rare case, having only 1 lens, and quite specialized one (I bet you have other camera system as well). But the majority has something like the standard zoom (typically 18-55mm) and a couple of shorter primes like 14/16/23/35/50mm. The rather big and heavy 90mm/2 is really seldom to see (and this is a much more useful fast portrait lens), just like the telezooms. Btw. if you are into macro, why don´t you have the 60mm macro already? Much smaller, lighter, cheaper and a bit faster.

zakaria: Weight and price are the weakest area for this aps/c lens.my dfa pentax 100mm is ff lens and almost half of the price and half the weight.

THe market will tell whether Fuji owners want a 750g macro lens. I guess this will be one of the least sold Fuji lenses. It might have optical quality (I do not doubt that), but almost all Fuji lenses are optically great AND most of them lightweight at the same time. And generally all macro lenses are optically great, especially super sharp (they have to be, since it is immediately obvious with macro shots, unlike portraits), so I dont think this one wiil stand out of the line to justify the size and weight. But as I said, time/sales will tell.

Thorsten: as David Kennard wrote, longer macro lenses serve also as portrait lenses. I use my 100mm/2,8 as a portrait lens more than for macro work. Of course just for macro you are right that you want sufficient DOF, so fast aperture is not critical, however f2,8 for a prime lens is not considered as actually fast. Plus, Fuji alone makes macro lens with f2,4 (XF 60mm), so go explain them what macrophotodraphy is about and that they shold have done it slower. ;-)

jadot: don´t act like you don´t understand. The example is clear: other producers can make similar lenses that are much smaller and lighter. And in theory a shorter FL lens (80mm vs. 100mm) for smaller sensor (APSC vs FF) for mirrorless (so less space-demanding than DSLR) should be smaller too. But no, this one is double the size/weight.
And besides, isn´t the main argument for mirorlees that the system is smaller/lighter than DSLR? What does it help when I save some weight on mirrorless body when I have lens with double the weight of an DSLR lens?

My macro lens is the sharpest lens I ever had, really high quality glass both optically and mechanically (full-metal body, weather-sealed...). Plus it is a DSLR lens (mirrorless lenses should be theoretically smaller), plus it has to cover FF, so a lot bigger area (so more/bigger glass elements). The only thing I take is OIS, but this only cannot add 120% more weight.

What´s not to like? As I wrote above, it weighs double the weight of FF DSLR macro lenses. What´s the point of going mirroless then, when I save some weight on the body, but at the same time I get it back on the lens.
IMHO -as much as I like Fujinon lenses - this is the most useless lens in Fuji lineup: a lot bigger, heawier /(but still slower) than 60mm/2,4 Macro, a lot slower than Fuji portrait lenses (90mm, 56mm). I gues of all 25 X-mount lenses this will be the last people will buy.

Richard Murdey: Ah, the commemorative two-year-mark "try and juice sales by re-painting the camera and putting it in a pretty box" event.

Speaking of two years ... when was the last time Ricoh announced a new K-mount lens?

cont.: So the fast development of lenses is not only desirable, but it is a question of survival of fullframe Pentax. Since in a year or so the great K-1 will be a mediocre camera among other FF competitors, so it needs to be strongly pushed by Ricoh now. And this is not possible without lenses.

Barbu: everyone knows that DFA 15-30 is a rebadged Tamron, so not much of a development. 55-300 is fast, but it´s an otherwise uninteresting lowend zoom with terrible luminosity (f6,3 at tele). The new fifty was introduced only as a mock-up in development and no sihgt of the real thing. The 85mm was not even shown as a mock-up, just verbalized, so it might also never come (as is usual with some roadmapped lenses, see the DA wide zoom that has been in the roadmap for 3 years or so without any hint of comming to life).
Yes, Pentax is a small brand, but so is Fuji and they introduced like double the lenses in last year or so (including completely new MF system). The K-1 is a great camera without doubt, but without lenses (and I mean modern, capable of resolving 36 MPx) it is only half usable. The thing is even worse that K-1 owners cannot buy Sigma or Tamron lenses that would substitute for missing native lenses.

Dear Ricoh,

we, Pentax users, really appreciate this new fancy colour. You know this is exactly what we need: more colours. Maybe red or pink would be fine too. And don´t worry with bringing those announced modern FF lenses (DFA 50mm/1,4, DFA 85mm/1,4) , those film era lenses are fine and perfect for 36 MPx sensor.
Don´t even bother with developing new APSC flagship, the K-3 II announced in April 2015 is still great, who needs an upgrade? We also dont need any more APSC lenses, so the DA wide zoom can stay in the roadmap for another 3 years.
Thank you for all you do and that you give no reason to listen to those bad rumours that Pentax is sinking.
Your happy customer.
