Nothing changes at the pixel level obviously.


Ok, but isn’t what you are describing not the effect of cropping but of amplifying a smaller format?

The dynamic range of a digital sensor is the range of brightness levels it can digitize. This is the absolute level of brightness from dark to bright before it clips (on the dark side) and saturates (on the bright side.)

A related measure is quantization resolution, which is the smallest change in brightness the sensor can detect. A well-designed system will match the electronic noise levels to below the quantization level so it is least noticeable.

None of these qualities change with cropping.

The perception of noise when amplifying a cropped image to the size of a “native” format may exceed the tonal resolution of the sensor but it will not degrade the dynamic range.

Dynamic range is not the difference between the lightest and darkest.
Dynamic range is how far the brightest spots in your image can vary from the darkest spots in your image and still maintain proper details in a single exposure.
When cropping, the noise level increases and the lower limit increases, so the difference decreases.

For me having one camera with full frame equivalent of 28mm, 35mm and 50mm at your fingertips without having to change lenses is very appealing during my travels. Not only that…having a monster 100mp image with great dynamic range and wonderful colours in my bag for landscapes is a bonus.

Yes one can get a smaller format camera with a mitt full of primes ( done and still do this for many years ) but having the same ability in one light package is just something totally different.

99% of photographers change field of view by zooming. Very practical and smaller negative effect to image quality than cropping.

I did not pre-order GFX100RF to crop. For me the 100mp sensor with 28mm eqv lens is the very point of the camera, not a bodus. I can crop if absolutely necessary. Everybody crops more or less... However, If I know I need to shoot at, say, 50mm eqv I take out Sony A7rv. Sony is faster operation, has better AF and IBIS, and also the lenses are brighter than f/4.

This looks like a great camera for backpacking trips, pull it out for on the run style shooting with good technique and on the tripod for the early and late hours of the day. No having to change lenses when the wind is howling and other weather is making life difficult. I think that is great.

I dont think lack of ibis will be a problem for the kind of work I do. Having extensively used a Pentax 67ii for 10 years, a 5dii until last year and now R5. Sure the R5 is a lot more advanced than my 5dii, but again it is almost only used on a tripod at the moment, so the ibis is not even beong used.
I would second the desire for a tele convertor, perhaps 1.5x.
I was wondering how high the pixel density and mp could increase on the RF sensor ?

How does cropping reduce DR?


Cropping increases the necessary magnification, which reduces DR as it is measured on the same output size. It is the same as shooting with a smaller sensor (imagine a crop applied on the sensor itself).

Regardless of the scene, the DR specifies how much noise you have in the deepest shadows. However, some scenes require lifting the deepest shadows, and others don't.

The point of understanding the dividing line where crop vs. lens magnification is ... I think is a salient one. Also, with the longer glass, the need for IBIS increases. The converse being with the wider FL, the need for IBIS is significantly less.

This ^ (and some other aspects) ... leads to the perspective, not of replacement (imo), but rather augmentation, for a 1 - 2 punch kit. Presently, I might carry my Q2 or M10R with a 24 or 35 / 40 / 50 mounted, and have the SL2-S in the bag with a 50 or 75 /85 / 135 / 500 mounted on it.

When carrying the Q2 (or M10R with lens of choice), the outing is that I'm not interested in changing lenses. Rather, if I need a longer focal length, I'll switch cameras ... to one that can have the tools of IBIS to accompany longer focal lengths (or slower shutter speeds, if desired).

For a given outing, I can roll with just the Q2 or M10R and no other lenses with me (i.e. pseudo "fixed" lens). There will be limits of what my 47 or 40 MP will let me do. The distortion on the Q2 will create certain issues for me, in certain scenarios.

In either case, I'm not seeing the Q2 or M10R as the "only" body ... and a body to replace the more "techno" IBIS body. My point being, that the fixed lens camera has a "time and place" for suitable use case. It isn't likely to be a replacement for other options ... BUT, instead is a tool that serves a DEDICATED subset, fit for purpose. And, within the context of that purpose makes a nice 1 - 2 punch.

Something line the combo of the GFX 100RF and an XT-5 with longer glass would be a superb approach for dedicated Fuji shooters, etc.

I'm not looking to swap out wholesale over to Fuji, per se ... but, the prospect of MF version of the Q2 has a certain appeal.
I've written elsewhere regarding the amount of crop that I feel is within reason for the Q2. And where Leica has the ability to offer up to 75mm crop ... it can / will. But, I kinda tap out around 50mm or less, with the 35-40 being about the sweet spot that gets "inside" the distortion of the 26mm lens (native), and isn't severely cropped, and drops me in the neighborhood of my M10R, still north of my SL2-S.

To that end, I think the GFX 100 RF will have similar utility, where the crop can be a useful tool, but not the end / all do all replacement for longer glass. And yet ... it should provide the flexibility, when desired (even if at some compromises for focal compression, pixel count reduction, etc.).


Short story ... it could be my 7, 8, 9, PW iron of choice. I'll have other clubs in the bag for the longer game.

I saw both at Fuji London. They both look great. The silver is quite bright and with not having a viewfinder window on the front it stands out as a large bright 'edge'. I pre-ordered the black for a more stealthy look though I normally opt for silver cameras when given the choice.

Everyone is different and everyone shoots different subjects. You say if you know you will shoot at 50mm, you’ll take another system. I personally value a compact light setup that gets me my shots.

What exactly do you need 100mp for?

That is a worst kind of first world problem

I can comment more if I really buy the GFX100RF. But definitely I know that I do not buy a 100mp sensor camera just to crop it heavily. For that there are so many better (and cheaper) option available.

I was good with 50MP on the X1D II. 47MP on the Q2 works. 40MP on the M10R, etc. I don't need 100MP for many things, and the MP count isn't the driver for MF (imo). To me, the driver for moving from smaller / cheaper > MF is the 16 bit file it offers. I can get 60MP in FF. I can't get 16 bit color files in FF. Today's glass in FF (options) is a stone's throw from MF glass in some regard. MP count is likewise a stone's throw from MF.

The color bit difference is the biggest separator from FF > MF that I can't achieve otherwise. With MP count, I can switch lenses vs. cropping and get to a similar image size / MP count from either way. Some folks might prefer the convenience of cropping, others might prefer to switch glass (and yes, compression diff's, etc.).


I think folks have to ask themselves what is it about MF that has them looking that way.

MP (total for print size enlargement)
MP (crop convenience to smaller print / online needs)
16 Bit Color
MF glass options
Other

Until you answer why you want MF ... well, you get the gist.

I don’t mind cropping. I crop a lot on my Q3 - yes I can get a Sony and several lenses to juggle instead, but that’s not comparing apples to apples. A small high megapixel camera is convenient for me in many, not all, cases. I carry one device, I don’t have to switch lenses, and I know I’ll get a high enough quality result every time. For documentary travel use it’s really ideal.

That said, if I was cropping heavily all the time, I’d probably look elsewhere. The Q3 works for me because I also do shoot at 28mm a lot. Same thing with this GFX, possibly. It’s not the cropping that’s the issue, for me at least.

And yes, absolutely first world problems. Not every camera is made for everyone.

Yep for documentary / travel the resulting cropped files are plenty. I too would look elsewhere if I wasn’t shooting mainly in the 28mm range…but that is where (28-35) i shoot the most so the range really fits. The convenience of going out with just one piece of equipment for the day cannot be overlooked. Couple that with the compact light setup along with great colours achieved from the medium format sensor and you get a great travel setup. It doesn’t hurt that you can throw in the RF into your pack and have a great 28mm landscape system.

Anyone know of any screen protectors on the market yet? Or does anyone know what the exact dimensions of the rear LCD are? I know the spec says 3.15", 3:2 aspect ratio, but I assume that's the display area, not the dimensions of the glass panel.

Everyone is different and have different use cases. I can only speak for myself.

I've said most of this elsewhere, but the more I think about it, the more I think I've come to understand why I'm buying this camera.

I own a Bronica SQ, 6x6 medium format camera.

I'm no good with the square format. I've tried, it's just hard for me (I keep trying though). One amazing thing though is the freedom to crop any aspect ratio afterwards and maintain tons of surface area for high quality prints.

You can go to 4:3, 16:9, 4:5, landscape to portrait without even rotating the camera, moving the camera from the tripod, crop in much tighter than your original shot, and still have higher image quality than 35mm film.

My understanding is that this is actually the norm, the rule, not the exception, in the commercial studio photography world, at least in the film days.

It can be, but isn't necessarily about magical "medium format" quality. It certainly isn't about shallow depth of field - full frame film options are better for that. It's about using the advantage of medium format by being able to crop and retain high print quality.

For me, the GFX100RF is no different, but in a digital, EDC package. Especially since it has the fixed lens.

I think there are many people who will hesitate to crop because they enjoy extreme, life-like detail. That's wonderful, and sometimes this camera can and will produce that. My father likes that, I don't begrudge him his X2D 100c.

But this camera is not only about that, and I think one can enjoy this camera more if they're not overly fixated about that.

It's clear that the designers aren't focused solely about that, given the dials and controls. I think the designers know the fun from their history of medium format cameras, the fun of X-Pan (sorry, TX), the craziness of Texas Leica 6:9, 645, challenge of 6x6, the history of 6:7, the pure insanity of 617, etc., etc.

Again, I just want a WCL because I've always wanted to shoot an X-Pan (sorry, TX) 45mm. Over the decades of my photography, I've always wanted to get good at WLF TLR style 6x6 street portraits (I've tried, I'm no good, but I keep trying). I've always wanted to shoot a Texas Leica. I want to channel my inner Richard Avedon. I like shooting my little X100V, whether with OVF, tilt LCD, or one handed, Tatsuo Suzuki style. Early on in my journey, I started with the 16:9 aspect ratio on my little Leica D-Lux 3. Lately, I've been bored with 3:2 and have been enjoying 4:3.

Now there's this camera that does all of that in one compact package.

I'm the last person who is in the market for a 44x33mm camera. I'm quite happy with my 24 megapixel GRIII, M10-P, X100V, etc. I never print bigger than 36 x 24 inches 72 dpi, 17 x 11 inches 300 dpi, 4K screen. I don't pixel peep. I know how to make my workflow sharpen images to give a highly-detailed yet natural, "medium format" look, if I want that.

Traditionally, I haven't been cropping my digital shots more than just the borders of my shots a little bit. Maybe I'll crop from 28mm equivalent to 35mm equivalent on my GRIII if I really need to, and it's right for that shot. It's rare though.

And yet I have a GFX100RF on pre-order for the reasons above.

And somehow, I think I am in the target market for this camera. Maybe not the marketer's target market -- because I was never in the target market for a Q3, M11 or even 40 megapixel X100VI.

But I'm certainly in the target market for the designers of the GFX100RF, the same designers that gave us that aspect ratio dial and crop dial.

I thought hard about this one -- I didn't want to spend $5k on a camera where I would be cropping most of that sensor that I "didn't really need (or want)". I dislike working with the 200 megabyte files from my dad's camera.

But then I saw one of the promo videos where one of the Fuji ambassadors talked about having, as part of their creative process, choosing their aspect ratio in the field and composing their shot that way, and that just resonated with me. I want to try that, and it's been a long time since I've been interested in a new camera.

I'm looking forward to the freedom of cropping digital. That *is* the advantage of medium format, at least for me.

I preordered the camera and then cancelled. My desire was primarily founded on wanting to try a medium format camera. My use case is predominantly landscape shooting, and I love the 28mm FL, so this camera definitely resonated with me.

But, the more I thought about it, the more I realized that this camera may not be the best vehicle for me to dabble with medium format. If it turns out I really like shooting medium format, I really can't take it any further due to the fixed lens. So I would end up having to buy another body and lens to further my journey. So I ordered the 100S II and the 35-70.

For me, this camera would sort of be a camera that I might come to at some later point, where I wanted more portability in medium format. But portability wasn't the main driver for me right now.

This is a much better move for anybody that wants to actually mess around with medium format in a more flexible way that you can see the results on a more consistent basis.
