  1. Cheers Bill. Nice shot as well by the way! I notified Jurgen as soon as I noticed the dust and attached an image to show him. He said he can't open the image and that I can basically unscrew the lens at the back and clean it myself. He said he doesn't understand how this can happen as he disassembled the lens to clean and adjust it. But it surely can't have happened in transport?! I'd send it back but I've already spent £28 import duty plus £45 on delivery. Can the rear part of the lens just unscrew? Alastair
  2. I've just bought a Zeiss Mess 524/2 off Certo6. The lens is supposed to have had a CLA but the amount of dust inside the lens is not good. It looks as though he was lucky enough to get a good model and just sold it on. For a lens to have this much dust inside after a CLA seems strange to me. Tell me your thoughts. How do I go about cleaning this dust. Do I take the lens apart? Kind regards Alastair
  3. Thanks for your response giovanni, I was hoping the gs645w would have such a mechanism. With regards to the gsw690, I'm using square filters and changing from t to 1 is not possible due to the lens hood. The camera manual actuallly states to advance the the film to end an exposure in this case. Not ideal I know :mad:
  4. Hey there, Does anyone know whether the T setting in the gs645w is the same as in the gsw690ii/iii? Part of me feels like I need this camera in my life but being a long exposure fan, I'm not sure I can be bothered to use the hat method and winding the film on to end an exposure. Could be a deal breaker. Cheers, Alastair
  5. Thanks Ferdi, Regarding my second question, I've read somewhere that the viewing lens on the 3.5f is actually 2.8, although I could be wrong (and I often am). With the filter holders I'm afraid the 100mm might be my only choice as I can then use it on my digital. I had an 85mm filter system from Formatt Hitech on my Fuji x-e2 and my images were vignetting when using the Samyang 12mm so I feel I just need to go bigger. You say the hard edge grads will be harder on medium format? I've had it in my head that the hard edge grad will appear softer edged on something like the Rollei's lens as it is quite small in diameter. A soft edge therefore will appear really soft as the grad width would almost cover the lens. Can you explain further? Thanks again, Alastair
  6. Thanks for all your replies regarding polarisers. Although, the question I'm asking is about grad filters, and the relationship between positioning on the viewing and taking lens. Would the effect appear the same on film as it looks through the viewfinder. Would it be the same with a smaller diameter lens such as the 3.5 or would I be better with the 2.8 as the lenses have a similar (if not the same) diameter. Alastair
  7. Thanks for your advice Ed. I have enjoyed my tlr for what it is for 15 years. I love landscapes and I love tlr's so I want to use filters. I use digital in a professional capacity and I am well aware of the advantages by my heart is with 6x6. Are you able to answer the question? Thanks again Ali
