|as the title,
any known hack to use other M42 lenses but without pressing dof button together with the shutter button ..
quite annoying and slow handling
I knew I will be sorry at one point for removing that tab from lenses ...
The only option I can think of is to use a Fujica AX5 35mm film body with the 'XD' adaptor fitted. This will allow the use of any auto-aperture M42 lens with open-aperture metering in 'Program' and 'Shutter priority' modes! Possibly the only camera ever to offer this functionality
A couple of things to note :-
i) Only the XD adaptor in the AX5 has this functionality, not the XS adaptor nor any other model camera in the range.
ii) The shutter in the AX5 (and others) is electronically controlled. The calibration is performed by fitting very low-value (difficult to find) capacitors, which have a tendency to fail and need replacing.
iii) The shutter in the AX5 (and others) gets "tired" eventually and is not reliable at high speeds. A clean/service may restore functionality, but re-calibration may be required ... see ii) above
This is all from personal experience. I used an AX5 for many years, primarily to take advantage of the widely available high-quality screw-fit primes that had become totally unfashionable in the '80's and '90's
The removal of the 'tab' on the aperture ring of the Fujinon lenses doesn't affect this functionality on the AX5 with adaptor, but of course limits it's use if ever you want to revert to the ST801. I bit the bullet and filed the tabs on all my Fujinons (and glued in the pin) so's I can use them easily on my Pentax DSLR's.
