I am qualified to discuss the GFX and other 44x33 formats.

In any case, you speculation isn't helpful. His answer might be.

Some Milvus lenses have a larger image circle than others. 35mm crop is better on FF lenses that have heavy vignette.
If it's manageable, you're right, shooting it at 50MP and then cropping it a bit will give better results.

This just opens of more options to swap lenses between my coming X-H1 to the GFX.


Sounds like we're in vehement agreement then... ;-)

Because you played with one for a few minutes? Or is it because you stayed at a Holiday Inn last night?

p.16 #4 · Adapting Lenses to the Fuji GFX


Since it is a really cold morning here in the Sierra foothills, and this warm cabin is so inviting when it is a bit lower than 20 degrees outside, and I have a cup of coffee on the table next to my computer... I'll reply before I put all of my warm clothes on and head down to photograph a cold winter day in Yosemite Valley. Lucky me! :-)

I dont really get the hostility in this thread ... I was merely stating for what I would want the GFX.

If thats somehow offensive then I'm sorry.


The "hostility" over camera format discussions baffled me, too. Too many go straight to ad hominem attacks as soon as anything less that effusive, unquestioning praise for their favored format (of all things!) is mentioned. (In the time it took me to type this, I see that another one jumped in to prove my point.)

Your post asked questions about some things that I've thought and written about and was in response to one of my earlier posts. But sometimes I'm unsure if a responder's message is actually a request for me to try to answer their questions or is more of a general post.

In the former case, I would offer a response. In the latter I might not. I was just wondering if yours were questions you were asking me to reply to, or if they were more general questions that don't warrant a specific response.

To clarify my general view at the current time — which is often either misunderstood or willfully misrepresented by some here at FM — I'm very interested in the miniMF 33x44 format, and I've been looking at it since the time that the Pentax 645d was first released, and considering it more seriously since Pentax updated that to the 645z, with essentially the same sensor as the GFX.

There are many things about miniMF that appeal to me: I prefer the 4:3 aspect ratio in much of my photography. A portion of my landscape photography would be suitable to the miniMF cameras. The larger sensor can provide some image quality advantages over the full frame system I currently use.

There are many things that I have considered in regard to deciding when and if I might acquire a miniMF system. They include: the quality obtainable from my current system, the kinds of photography I do, the increment of the image quality differences as seen in large prints, the financial costs, the availability (or lack thereof) of types of lenses that I rely on in my work, how the miniMF system would fit into the larger set of systems I use for my photography.

I remain intrigued, but for my own photography I'm unconvinced at this time that the pluses of miniMF outweigh the minuses for me and my photography. I've explained my thinking extensively here and at my website, so I won't recap all of it here.

I'm not saying, nor have I ever said, that the GFX is anything buy a fine camera. My experience with it demonstrated that it can produce excellent image quality and that it is a well-designed and very functional camera. (Functionally, it reminded me a great deal of my other Fujifilm cameras, which I rely on heavily in parts of my photography.)

I remain interested. Things that are likely to increase my interest to the point that I might well acquire a miniMF system like the GFX include:

- introduction of a sensor that significantly surpasses the pixel resolution of full frame systems.

- introduction of native Fujifilm lenses that meet some of my needs not met by currently-available lenses.

- improvements in the AF performance of Fujifilm 1.5x cropped sensor bodies to the point that they could become my primary cameras for my wildlife photography, making it less necessary for me to continue to use a DSLR. (E.g. — moving to a Fujifilm-only system with a 1.5x smaller system for most handheld work and a miniMF system for most tripod-based work.)

It is possible for skillful, talented, smart photographers to come to more than one conclusion about the value of current miniMF systems for their photography. I have friends who use 33x44 sensor miniMF systems. (They moved down to miniMF from old-school MF and from LF film, and they feel that the quality of miniMF doesn't leave much "on the table" by comparison to what they had been using, while offering some functional advantages. They also all use FF systems.) Many others continue to use a range of FF systems from all of the vendors you can think of. Many of us also incorporate smaller sensor systems into our photography. Thus...

YMMV,

Dan

BTW: One way to deal with forum trolls is the hide me link. You can still see their post if you wish, but it is a constant reminder that replying to their insulting, demeaning posts isn't worth your time.

molson's post is hidden · Show · Unhide member · Unhide all · Hidden list

And – not writing to Sauseschritt here! — any others in the forum find themselves so angered by the mere presence of my posts that they are unable to suppress their instinct to hurl more invective... why don't you guys hide me? It will be good for your blood pressure. It will be good for the overall civility of the forum. My feelings won't be hurt. Try it.

@gdanmitchell, can we not getting into this kind of argument? i mean it seem like on every single thread, you would type a long long respond and quite frankly, i don't think anyone would sit there and read it. No disrespect but can we keep it short? How about write a blog about this stuff (medium format) and each time, just put a link to it. That way, we don't have to scroll? i don't want to hide you since you do have some good stuff going on some time.

There are many things that I have considered in regard to deciding when and if I might acquire a miniMF system.

As long as you keep referring to the GFX, X1D, 645z and any other 44x33 format camera that comes down the pike as as "miniMF", it is hard to believe that you were objective in your intent.

Be that as it may, you are on Facebook so you'll be able to view this link.

GFX Facebook forum photo link

These images by proficient photographers (not to insinuate that you are not one yourself) illustrate the IQ benefit of this format and native lenses over the 5DsR and its native lenses for certain types of photography. There's also an X1D forum as well.

In addition to the improved IQ, the mirrorless 44x33 cameras offer a size and weight that makes the cameras wilderness/hiking/landscape shooting-friendly.

Actually I was allowed access to the group by the administrators, without answering the silly questions. Lots of nice images in there, a good representation of medium format well used.

I just discovered that this thread now appears in both the Fuji Forum as well as the Alternative Gear and Lenses Forum. If I may ask, which forum is actually official for the GFX? I can see why this thread was moved here (the AG&L) b/c the original topic was about alt lenses for the GFX.

Also, I thought I was discussing the GFX in Dan's original thread to the Fuji Forum. My bad and my apologies to the AG&L community for taking this thread off-topic.

It's unfortunate that someone chose to share this and other Fuji-specific threads with unrelated forums. I'm sure Fred had good intentions when he implemented this feature, but it's an annoyance at best, and a a troll-baiting mechanism at worst.

These are tests for coverage and vignetting only. The Techart shots were shot with af but focus was not verified so any poor resolution should not be concluded to due to either sample or general problems with the lenses. Laowa focus was verified by visual examination and change of the focus based on peaking and likewise no conclusion should be drawn about resolution based on these tests. The only thing these are intended to show is vignetting and coverage.

I set up this thread and from the very beginning I included it on both the Fuji and the Alternative forums. I did this because it is a Fuji camera (obviously relevant to the Fuji forum), but it is about using alternative lenses on that camera (seems to me obviously related to the Alt forum in which many threads are about adapted/alternative lenses). Where I think the thread went off the rails a bit is when the comparisons with Canon DSLRs became a big issue. I don't think that had anything to do with the thread being on both the Fuji and Alt forums. By the way, when a thread has a dot before the first word it is shared on multiple forums.

Steve. I have the Kipon shift P67-GFX in my grubby hands! I'm using it with Pentax-6X7 45mm. Works a treat, can shift both vertically and horizontal.


Hi, I'm asking this question of fishjump, apologies if I have done this all wrong since I have never posted on this forum before.

I'm curious what you encountered as far as distortion with the P67 45mm lens you have pictured in your post. I bought a P645 35mm lens and a Kipon shift adapter (P645 – EF since at the time the G adapters weren't available). The lens was terrific except from a distortion perspective it was unusable for my architecture and interior work. Shifting anywhere out of the centre of the image circle takes the distortion off centre and therefore makes it impossible to correct in post — there is a way but it's not practical. Not only was the distortion unfixable, but it makes lining up shots very difficult to begin with, especially given that on the GFX (or any camera I have used for that matter) the digital level meter is not 100% accurate.

If anybody else has anything to add please do. I see a lot of people online adapting various MF lenses onto GFX with the various shift adapters but nobody ever mentions distortion. I found one guy that had done a bunch of test shots and made them available to download (Contax 645 35mm, Hasselblad 50mm, P67 45mm, P645 35 & P645 55mm). They were somewhat informative yet the test subject was a room with wonky walls and a partially un-lined timber wall (studs etc. not very plumb): hence it is very hard to tell what is lens distortion and what is just sloppy craftsmanship.

I've settled on a Canon TSE 45mm for the time being, which has a lot less distortion than the Pentax and is actually a pretty decent lens (shows better performance on the GFX than on the Canons, and I have a reconditioned copy which along with my other Canon shift lenses is a lot better than what comes from the factory). It does a reasonable amount of shift but CA is an issue. It isn't exceptional when it comes to flare but neither was the Pentax.

Thanks
