Yes, GF35/1.7 or 2 would be a great companion to the 55. Plus a fast prime in between the 110 and 250. And an Astro fast prime. That's not too much to ask is it?
You already have that with aps-c cameras. And with full frame cameras. Why in the world do you need that with medium format? To complain that lens was too big, left it home?
So you choose your format based on the focal length you want to shoot? I would like to have full coverage in any format I choose. Why in the world do you have a Gfx if you see no reason to have medium format? I have the Xf18/1.4 and love it. I just want its equivalent in Gfx.
And I agree with you, but the damn laws of physics are the same for all of us. What you "want" is absolutely not practical. I personally could not care less about bokeh, or night photography. Top notch compact f/2.8 or even f/4 lenses that focus quickly would be perfect for me.

Sure, its going to be heavy, I never said it had to be lighter than the 55/1.7. I would be perfectly happy with an f2 version that weighed the same as the 55/1.7. And from your estimates that looks do-able. I don't see much point in a 35/2.8 when you have the 30 and 45 in the vicinity. My current 35 prime for Gfx is the Contax 35/3.5 and its heavier than the 55. If I want lightweight for what I am doing I take my X mount setup.

Sure, but you should get your equivalence numbers right. If you get what you want with 18/1.4 on APS-C, you will get what you want with 35/2.8 on 33x44 (if both cameras have roughly the same sensor tech level).

Now, that doesn't exist either, but the chances of one coming is at least higher than for a 35/1.7.

JadedWriter wroteI honestly just call the 80 a "long 50." I mained that thing for a few months...I think before I got the 55...and then the 20-35. For portrait and studio use you honestly don't need more than the 80 depending on use case and working distances.
I don’t do portraits or shoot in a studio, and to me the 80 is always too long. I don't think I've used it even once without whishing it was shorter.

The 55 mm focal length is perfect for most of what I do though. I just dislike the size, weight and AF (which are all identically bad on the 80).
gf30 is a great lens and does what you want.
Not exactly, but close. He'd need a ~35/2.8 for equivalence. IMO the difference between 30 and 35 is pretty darn big if you like one over the other. I often use the 35-70 @ 35, but I think the 30/3.5 is too wide almost every time I use it.
I use the GF30 for portraits. And since I almost never photograph with GF55 wide open, I just got the GF 32-64mm so I can cover portrait photography with a single lens. I like being able to reach 64mm, but it also seems to focus much faster and more confidently. Hasselblad still does it better, though, so it is a clash of titans.


Maybe the 50/3.5 would be a good lens for you? It's very small, very sharp, has nice bokeh, focuses fast.

You didn't even try, did you. LLMs are literally contextual text prediction machines, they don't do any real math. They don't have any understanding. They are not 'intelligent'.

Lenses with a similar open aperture size (eg. 27/1.2 APSC and 35/1.4 FF) have very similar weight.

But then you're not equivalent to the 18/1.4 that you said you wanted. Not that f/3.5 gives you that, but you don't need faster than f/2.8 if f/1.4 is fine on APS-C.
AI did a napkin math and came up with GF 35mm f/1.4 that would be about:
Weight: 1,300 to 1,800 grams
Length: 125 to 145 mm
Diameter: 95 to 110 mm
Filter: 95 mm or 105 mm

You will take this lens to anywhere once, and then you put it in the least used camera bag and forget you have it. Most people think xf18/1.4 is on a heavy side...
Why not? It is all a game. Its numbers are better approximation than mine.

The manual focus 30/2.4 ZhongYi lens is very small, both in length and girth. If it were made a unit focus lens I would posit it would be lighter than the GF 30/3.5. the compromise there was huge distortion, but a more competent lens designer could achieve a better set of compromises.

Yes, and I'm sure the people at Zeiss or Voigtländer and a few other companies could do very nice GFX lenses if they wanted. But I also understand that there probably is very little economic gain in doing so, considering the small market.

I don't mind weight too much as long as it's located close to the camera. A good example is the 100-200 that looks very front heavy, but in practice it feels much lighter than it is because the weight is not mostly at the front. The 55 seems to have most of the weight at the front which makes it terrible in that respect.

Personally I'd want a manual focus ~55/2 lens. I borrowed a Mamiya 55/2.8 from a friend that is definitely small enough even with adapter, but the optical performance is really crappy.
I'll continue to use the 50/3.5 and 55/1.7 depending on how much I'm willing to carry for the moment.

If I was going to be happy with that I would've just bought the 45 2.8 by now and even if I do cave and buy that lens I'm getting rid of it the moment something like a 35 1.7 or F2 got announced any way.

I actually started using it instead of gf55 lately, especially in studio where apertures normally start at f/5.6 for me. It is a great little lens. (But I also got HB, and because its autofocus is significantly better there are not many reasons to shoot GFX anymore).

Trying both for yourself and deciding which you like best is, of course, always the right answer if financially feasible.

This thread has done a more than adequate job of proving why that is.

So far I’ve only tried the GF 45, but as far as 35mm equivalent focal lengths go it has a beautiful depth, sharpness and contrast even at f11 that is very pleasing. And at f2.8 close to the subject produces beautiful bokeh and sharpness.

They're not going line by line thinking I want something unrealistic. I have said twice in this discussion that I'd be happy with 1.7 or F2. Please drop it and go along your merry way please.

I've used them all, I run a local 30bn parameter mixture of experts model that rivals frontier models. I've trained my own LLMs and distilled others. I have a comp sci degree and have coded for a living.

They appear intelligent to those who don't know enough about the subject matter they're asking it. They can help with certain tasks if it's not less efficient to check all their work rather than doing it yourself. Typing a prompt into claude is a low bar for an 'experiment'

Back on topic.

Since I have both lenses perhaps I should do a shoot-out comparing them. OP do you have subject matter in mind? Indoor portraits?

Definitely not my forte.
55/1.7 wide open






45/2.8 wide open






This is what I shoot more of, both 45/2.8

I have both lenses. If I were forced to choose, I'd keep the 45.
Get this, the 55 is a "better" lens.

I'd keep the 45. It's light, has a comfortable angle of view (more or less a 35mm f/2 in ff terms). It is VERY sharp, corner to corner. It balances on the GFX bodies well. It feels "friendly" and nimble - how's that for subjective? It's a bargain on the used market in "new" condition.

The 55 is a tank. If you need really thin selective focus, it's worth dragging around like an albatross around your neck (or back). It renders beautifully. It does not balance well on the GFX bodies (but that's true of most of the GF lenses). I don't like it very much. It doesn't feel "friendly" and is definitely not nimble.
