I, for one, would rather use a 35mm equiv than a 31mm equiv. To me, 31mm is closer to 28mm.

Precisely. Especially if said lens is your one and only lens for a year.

But it's not 31mm equivalent, it's right at 35mm.

That is exactly what is up for debate!

Not between 31mm and 35mm equivalent though.

.. are without a doubt, the most pointless and boring topics on DPR. Period.

Seriously... 63 posts to try and decide if a lens is 'the same' or 'different' to another lens

Jeeze... bring me the blue pill!

You mean Viagra? Good grief, that's a strange reply in this context.

But not mostly about equivalency, mostly about the FOV and not wanting it to be too close to the 18mm lens.

Re: Actual FOV 23 f2 not 35mm equivalent?

Exactly.  35 to 31 is a modest difference, let alone the actual difference between the two 23mm Fujis.  Yet here we are debating it.  Chucking in simply incorrect theory too (not directed at Mr Prevatt of course).  I often wonder how many people on threads like this actually take photographs for fun or work rather than simply enjoy and debate the gear.

Someone up thread has said they own both 23mm lenses and the difference is of no consequence.  Crop factors is as close to 1.5 as makes no difference (1.52 or 1.53 width and height).

Were photography based on a need to conduct exact calculations to take good photos the differences are barely noticeable, as what we do is judge the results visually nothing in this thread is at a magnitude where it matters, even remotely.

Keep in mind that these are photographic lenses (not cine or scientific) and control and measurement of the focal length isn’t terribly critical. The 23mm may not even be 23mm, and it most certainly changes as the focus distance changes. But 35mm is prolly close enough

So?

Just use it for what it is. Is there a reason it has to be precisely 35mm? Is there a reason 31mm won't work?

Many users have been making great images from that lens without worrying about the exact maths. I don't own it so I'm not defending it. I just don't get the concern. If anything, for me at least, the fact that it is slightly wider would increase its appeal. Once I owned it though I wouldn't worry about equivalence, I'd just use it for what it is.

Everyone equivocates, it's just a fact of life. Ha ha.

Yes, it is one more step in from my comfort zone for 35mm.  If you are used to a particular focal length and know what will be in your frame before you bring the camera to your eye, it could be something that effects your shooting.  It is not a big deal to some, and it is a big deal to others. It really depends on how you shoot.

Ok, well I think a previous poster showed the angle of view should be what you expect from this lens, so you're good to go.

I was speaking hypothetically of course... I use the X100F as my 23mm.

Re: Actual FOV 23 f2 not 35mm equivalent?

Hi there, and thanks for your input. I am about to purchase the GFX 100 and I need to know the widest lens possible I would be able to use- no matter what the manufacture or intended format, with adapters or what have you. I appreciate any input and insight you may have. Again thank you so much.

Good question, but unfortunately, wrong forum.  Questions and discussions relating to Fujifilm's medium format cameras belong in the Medium Format Forum, here:
