Just picked up an SP Adaptall 06b mirror lens at a photo gear market.
So cheap I'm too embarrassed to mention the cost. It appears to take nice shots. Comes with all the filters including the front 82mm filter. The problem is the filter is tightly fit on the inside rear of the hood. I'd like to try the lens without this filter on. Can't get it off. Anyone had the same problem? Perhaps the filter is meant to stay with the hood? Solution without breaking the filter (Plan B)? Suppose I could use with a temporary makeshift hood and if performance is distinctly better go to plan B.

In this sort of situation there are three things that are your friiends. Lubrication, thermal expansion and patience
I would try
1) let some WD40 or similar release oil soak into the joint between the two offending pieces (not very much oil!). Leave for 24 hours. Try to unscrew it.
2) Heat the outer component more than the inner AND/OR cool the inner component more than the outer. For example, leave in the fridge overnight (in a plastic bag with a silica gel packet) then warm the outer component with your hand. Try to unscrew it.
3) If it's that valuable, give up and accept that patience is a virtue and some day you'll find a way to separate them |

So tried without Hood/filter. Filter definitely adds some CA, just as happens with my 3M-5A mirror with filter.
Here is a photo without filter:

Success! Found a plastic cap in kitchen that fitted neatly inside hood. Wrapped it in thin rubber glove and using pressure and twist, it unscrewed, in the manner of good advice on this forum for removing front name rings on lenses.
Just discovered that the tripod ring easily is moved between horizontal and vertical positions. Another bonus.
cheers to all

Certainly is. Very common in Perth gardens and usually willing to model for photographers! _________________ K5, K20D, Bigma, Sigma EX 105, Sigma EX 10-20, Sigma EX 28-70 F2.8, Sigma Ex 1.4TC,
