I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.

The only real problem is the file size, which is truly enormous even when using JPEG (superfine). To reduce the amount of data, I skip the 4:3 aspect ratio and shoot in 3:2 or 16:9 (the number of horizontal pixels doesn't change, so sharpness isn't affected). You'll still need a powerful PC and a LOT of patience, especially if you'll be using denoising programs.

I think it also depends on the lens model. I also use a Manfrotto 055 for night photography or with filters: I've had poor results with the 45-100 because it's very biased toward the front and therefore sensitive to even the slightest disturbance. No problems with the 20-35 (not biased) or the lightweight 35-70 kit. A tip: to improve stability, there are accessories that screw onto the base of the camera with a forward-facing bracket that better supports the lens. In any case, camera shake is always a possibility...

I've had problems too, especially with a 45-100mm f/3.5-5.6 that produced a very annoying variable-frequency hissing sound. I sent it for service in Italy and was replaced with a completely silent model... but I had to wait over a month to get the exchange. The camera body can make some noise when using non-FUJI lenses: I sometimes use a Pentax 645 macro, and the noise coming out of the camera is the sensor image stabilization.

Anche io ho avuto problemi, soprattutto con un esemplare di 45-100 che produceva un suono sibilante a frequenza variabile molto fastidioso. L'ho inviato in assistenza in Italia ed è stato sostituito con un esemplare completamente silenzioso...ma ho dovuto aspettare più di un mese per ottenere lo scambio. Il corpo macchina può emettere qualche suono quando si montano obiettivi non FUJI: uso talvolta un Pentax 645 macro ed il rumore che esce dalla macchina è lo stabilizzatore sul sensore.

Secondo me dipende dal modello di obiettivo. Anche io uso un Manfrotto 055 per foto notturne o con filtri: con il 45-100 ho avuto risultati scadenti, perchè molto sbilanciato in avanti e quindi sensibile ad ogni minimo disturbo. Nessun problema con 20-35 (non sbilanciato) e con il leggero 35-70kit. Un suggerimento: per migliorare la stabilità esistono accessori da avvitare alla base della fotocamera con una staffa rivolta in avanti che sorregge meglio l'obiettivo. In ogni caso, il micromosso è sempre in agguato...

Ciao l'unico vero problema è la dimensione del file, davvero enorme anche usando il JPEG (superfine). Per ridurre la mole di dati, lascio perdere il 4:3 e faccio foto in 3:2 o 16:9 (il numero di pixel orizzontali non cambia e quindi non si riduce la nitidezza). Dovrai comunque avere un PC potente e avere MOLTA pazienza soprattutto se userai programmi di denoising...

I think I have the gift of foresight... 📸 The GF500 f5.6 is a reality! And at an affordable price, too...

Dear friend, I had the GF 23 and 30 and I replaced them both with the GF20-35. No regrets: the zoom is of the highest level, not heavy and of similar dimensions to the 23mm. You can find some photos in my gallery. Don't think twice: 20-35 for life... The Laowa is a good lens but if you try the Fuji zoom you will never go back.

I got it right!!! As I asked some time ago, Fuji is working on a GFX 500 f5.6! That is, EXACTLY what was missing from the road map of objectives.

You have to go to the menu and activate shooting with various types of lenses and an adapter ring. Find the instructions on p. 127 of the manual. I easily configured the camera to use Pentax 6x4.5 lenses

HI I bought the GF 20-35 a few weeks ago and I am very satisfied. The sharpness is formidable from edge to edge, the construction rock solid, the balance excellent. At the same time I also used the GF 23: the performance of the two lenses are similar but the zoom is much more versatile. In my PHOTO gallery you can see some shots taken with the GF 20-35. The only flaw is the very high price but still well below, for example, the Hasselblad prices.

The FUJI GFX catalog lacks a "serious" telephoto lens. In fact, the choice stops at the GF250, which corresponds to a 200 on the full frame. I hope that at least a 400 or 500mm will be built and produced soon, perhaps not too bright otherwise it would be too heavy. For example a 400f5,6 or a 500f6,3 (naturally with the possibility of mounting the 1,4X): in this way, even the price would not be..."crazy"

Dear friends I ask you all: in your opinion, which lenses are missing in the GFX catalogue? In my opinion, for example, a telephoto lens is missing, such as a 400mm f4 or a 500mm f 5.6 or f8. In fact, I find it strange that FUJI stops at the GFX250... What do you think about this?
