gravastar Posted October 10, 2013 Share #21 Posted October 10, 2013 Advertisement (gone after registration) Teamwork Photo in London have just shipped a Big Stopper for the RF75/System Seven5 to me. I placed the order today, so they were in stock this morning. Most other UK retailers seem to be quoting long lead times on this item. Bob. Link to post Share on other sites More sharing options...
Advertisement Posted October 10, 2013 Posted October 10, 2013 Hi gravastar, Take a look here M 240: Lee Filter Holder Seven5 or RF75?. I'm sure you'll find what you were looking for!
Guest NEIL-D-WILLIAMS Posted October 11, 2013 Share #22 Posted October 11, 2013 So, are you saying, and you have tested this, that this method allows an exposure of longer than 60 seconds?No sir I have not as I am sat on an Oil Rig in Nigeria right now, but I will be back home next week and I will give it a try and see what happens Link to post Share on other sites More sharing options...
gravastar Posted October 11, 2013 Share #23 Posted October 11, 2013 In conjunction with the self-timer, a T function is also available: If isset and the self-timer is activated by tapping the shutter release button (see also p. 150), the shutter opens automatically after the selected delay time. It then remains open until you press the shutter release button a second time – you do not need to hold the button down. Unfortunately the shutter closed after 60 sec, less at high ISOs. No extension beyond 60 sec. Bob. Link to post Share on other sites More sharing options...

Thats bad news..............I just bought a 10 stop for my Noctilux, cant remember if 60 seconds is going to be long enough for a daytime long exposure:confused: Link to post Share on other sites More sharing options...

richardcurtis Posted October 11, 2013 Share #29 Posted October 11, 2013 The Lee Seven5 filters work great with the M240. I used a big stopper and ND Grad .6 recently on a trip to Norway. The only annoying element is the 1minute maximum exposure time. Otherwise, this camera is amazingly flexible and very happy with the Landscapes shots. Image are here http://www.richard-curtis.net (under Norway)..Images 10,12 and 13 are used with a filter, processed in Lightroom 5 using VSCO B&W presets and of course a few local adjustments.
