Canon 50/1:1.2 front element & filter proximity query

[jt991]

 

If you have a Canon 7 (or 7s) with the 1.2 50mm lens, have you found that when fitting a filter it touches the lens surface ? <br />In anticipation of a 7 with a 1.2 50 lens arriving next week I came across this 'warning' in a forum which recommended two Makes of filter that won't (<em>perhaps</em> Hoya and B&W) and seek advice accordingly here.

<p>I don't have the lens, but I've seen two easy solutions. One is to put a large, thin o-ring on the filter threads to keep it from going on all the way. The second idea seems better: to buy another filter and pop out the glass, then use that under a normal filter.</p>

I would post your query in the Leica and rangefinder forum. There is usually enough space even in older lenses to clear the front element of most name brand filters. At least in my experience. Certainly with lenses that are not super wide angle where front element is highly curved.
