    I've found that they only way I can use my Lee filter system (for ND grads etc) on my GSW 690 is to stack sufficient screw-on filters so that they protrude past the lens shade. This is clearly a problem if I don't want to use a screw-on filter! I realise I could use a couple of UV filters, but I don't like to add unnecessary glass in front of the lens. Has anyone found a way to remove the lens shade? I am wary of doing anything that may damage the front element, or lead to dust etc. in the shutter - I don't mind if the removal process is irreversible.

    Yes, I have done this on a GSW 690III. I posted my experience on, but will re-quote it below.

    ...after a very frustrating weekend taking Cokin adapters on and off so I could change the shutter speed, I resolved to have a try. I did do a little more research on various mailing lists and found a couple more bits of advice: (a) It is much easier to remove the hood by disassembling the lens body, and (b) any attempt to disassemble the lens body is a recipe for guaranteed disaster as there are springs under tension inside. Faced with these incompatible pieces of advice, I decided to place it safe and avoid the disassembly method.

    So today I bought a little razor saw from a hobby shop, wrapped the camera in several layers of cling wrap, put several thick rubber bands around the lens just behind the hood, put a clear filter AND a 67mm lens cap on to protect the front element, and set to work. It soon became apparent that the hood is the strongest part of the camera (more strange Fuji engineering!). I stopped frequently to wipe the filings away, and turned the camera upside down so that if I did do any cosmetic damage it would be less conspicuous. I got through the front part fairly quickly, but the rear is made of thicker metal. After a while I was going very slowly indeed, checking and cleaning after every couple of strokes of the saw. When there was still a bit of metal about 8mm long and 1mm deep joining the two sides of the cut, I realised that I could probably fit a small screwdriver blade in and work the cut a bit so that the remaining metal would get brittle and break. This I did and after a minute or so it broke and I was able to remove the hood easily. I then carefully wiped away as much of the filings as I could and then gave it a thorough clean with compressed air before removing the cling wrap. There is a tiny bit of scraping visible on the plastic retaining ring under the hood but that is all. The camera doesn't look too bad without its hood and since I never intend to sell it I'm not worried about the resale value. The hood has retained its shape so if I really wanted to I could refit it and cover the slot with some plastic tape, not that I would want to. I will now try and find a suitable 67mm collapsible lens hood that does not vignette. Looks like I got away with it!

    Your results may vary.
