p.1 #1 · p.1 #1 · Test: Fujinon GF 45/2.8 vs GF 50/3.5


For those of you who don't know which of these lenses to get, I put together a little test this evening. You can find two zip files here; one with JPG's and one with RAW's: https://www.dropbox.com/sh/lmc7crhz4k4srva/AABAmjCYR4l1ieYr9jwFuvdaa?dl=0
There are four scenes at different focus distance. Everything is shot on tripod with timer and refocused between every shot. I also used the same white balance for all shots (not auto), so the JPG's are probably good enough for evaluating.

Personally, I like the draw of the 50 better, and I would only choose the 45 if I needed f/2.8 and/or the very slightly shorter focal length. I think some people have made up their mind about the 50 being "inferior" only because it's cheaper, slower and smaller. In my opinion, they are wrong. It's up there with all the other GF lenses and certainly belong in a professional photographers bag, if it serves a purpose.

I will keep the 45 but probably only use it for low light or when I want maximum separation, which isn't often. The difference in DOF isn't that big actually, and I love the 50 for walkaround use.

Thanks, you saved me some cash and from GAS. I have just one native lens - 50R and it reminds me of the 27mm for the X series in terms of FOV but with much smoother rendering!

Sounds good to me.. the 50R is tempting with the 50mm f/3.5 and perhaps later the upcoming 80mm f/1.7. Would make a nice combo.

Fuji needs to make a faster primes in this focal length range. Yes I know bigger, heavier and more $$. If I was worried about those, I will be shooting Fuji XF. 45mm f2.8 is nice but should have been f2.

Agree a 45/2 would have been awesome.

the starter kit 50r+50/3.5 is a very nice one especially at the current prices. I am going to wait for the 80mm. For the rest of the focal lengths do the MF folks on the forum use the X system or a FF system?

I use my GFX 50R on a tripod 98% of the time, and I only have one Fuji GF lens: the GF 63/2.8. It's my "not on the tripod" lens. Everything else is adapted lenses -- mostly Pentax 645, but some other specialized ones like a Schneider Kreuznach Apo Digitar 80mm f/4 and a Rodenstock Rodagon-WA 120mm f/5.6.

Pentax 645 lenses are inexpensive and excellent. There's a narrative out there that says they're old designs, not up to the Fuji GF standard, etc. I don't think that's true as a general statement. For example, I did an exhaustive comparison of my GF 63/2.8 to the 63mm position on my Pentax 645 45-85mm f/4.5 zoom. The old Pentax zoom holds its own no problem. If you're curious, the results (and RAW files you can download to see for yourself) can be seen here: https://www.dpreview.com/forums/thread/4467565

I do have a Sony camera and lots of lenses for it, but I never use it anymore. The GFX is so much more rewarding and I don't need more than a few focal lengths. Right now this is my kit:

Schneider-Kreuznach 28/2.8 PC
Fuji GF 45/2.8
Fuji GF 50/3.5
Fuji GF 63/2.8
Mitakon 65/1.4
Fuji GF 110/2

I almost only use the 50/3.5 though, since I like the focal length and it's just as good as the other lenses. The 110 is wondful but I have not idea of what the heck I should use it for. It's always too long.
The Schneider don't see much use either but is there for those occasions when I want something wider than 45. Just in case (like, almost never).
The Mitakon... Well, I want to like it, but I hate it. The rendering is awful for what I want to do.

If Fuji made a ~55/2, that could be my only lens.

Edit: The 80/1.7 I don't understand at all. Why on earth 80 mm What purpose is it for? A very long normal or a very short tele. Just bleh. They should have made a 65/1.7 instead.

I took my GFX 50R/50 combo and a Sony system (lox 21, lox 50, 70-400) to Yosemite a month ago, and I used the GFX mostly except for some tele landscapes during Sunset. The 400mm read was very useful.

Interestingly, the Sony R2+70-400mm was my tripod setup for landscape and the GFX was my point and shoot

Oy! I really like 80mm!

My favourite focal lengths are just a bit longer than normal and just a bit wider than normal. So 80mm makes sense to me. If I could only have one lens, it would be my SMC Pentax-A 645 45-85mm f/4.5 because it covers my most-used focal lengths and shifts well. If I could only have one Fuji GF lens, I think it would be the 45-100mm.

I had to think hard about what my only Fuji GF lens would be, and I chosen the 63/2.8 over the 55 (which was cheaper) because if push comes to shove I use normal more than wide(ish) focal lengths. The 63/2.8 is really good too by the way. I don't shoot pictures of things that are moving quickly so the apparently slower autofocus is just fine for me.

When they 44 X 33 sensor uses the full 4 X 3 aspect ratio and you compare a 4 X 3 crop on FF 35mm, 80mm is the equiv of 58mm. That is a pretty classic focal length on FF 35mm and an angle of view I like a lot. Nothing weird at all about it.

I have a Mamiya 80/1.9 that has been waiting for an adapter for two months, which is pretty frustrating. So we'll see if I can find any use for it. Probably not.
58 mm on FF is also very, very strange to me. Always too long for what I want to do. Especially fast lenses where I want to blur the background are totally inconvenient if they are longish, since then I don't get enough of the background in the photo. What's the point with thin DOF if there's no background to blur?

I had the 55. I borrowed a 50 and immediately bought one. Then almost as quickly sold the 55. Perhaps there is sample variation, but my 50 is stellar. For my style of shooting, there is little need for more optical speed in those focal ranges.

I have both the 50 and 55 (and 45), and I've been using the 55 a lot more since I bought it. But now I'm gonna pick up the 50 more again to get rid of some weight.

All depends on what you shoot, isn't it? Personally for me Canon 50mm f2.8 TSE does it for shots of buildings, landscapes etc. So far I have held off 55mm f1.7 but would be handy for environmental portrait shots at wider apertures.

The GF 50 is a gem, but my only complaint is the long minimum focus distance. If the MFD limitation was not mechanical in nature but due to IQ, I wish Fujifilm would have allowed a closer MFD but perhaps forcing a maximum aperture of f/4.5 or f/5.6 for "macro" distances.

My guess is that it's both mechanical and optical. With internal focusing and floating lens groups, you simply cannot focus closer by just moving the whole lens assembly farther away from the camera, like you do on traditional lenses. You'd have to completely change the lens design.

What you can do is bring a good (achromatic) close-up lens. It will shorten the focal length and most likely give curvature of field, but that doesn't necessarily matter at very close range anyway.

The gfx to fx crop factor is about .79, call it .8 for faster math. Thus the 80 is about a 64 equivalent out of the gate. If you crop 24x36 to 4:5, yes the 58 becomes very close to that same focal/perspective, and yes itís a great lifestyle focal.

Me personally, I want something in that range but would prefer better af, hence me considering, probably a Canon, 85 and adapter as my option. But yes, the 80/1.7 is a great lifestyle choice 👍
