UV/IR cut filters question

I am a new owner of an A7, and have a selection of Voigtlander lenses from 12mm to 50mm, and these will be the main lenses I'll be using on my new camera until I can afford some decent FE glass. My other camera is a Leica M8, so my lenses have the Leica UV/IR cut filter attached, as there generally required for colour photography on the M8. So my question is around whether the filters should be removed or not when the lenses are used on the A7, or whether 'double IR filtering' has no effect anyway, and whether there were any negative factors for leaving them attached. I don't have any skylight filters to replace them, and i don't wish to keep changing filters constantly, so before spending out on new filters, if anyone with some experience here could share their observations I'd be grateful.

Those filters should be fine. A skylight filter is not necessary for digital photography anyway.

 

Personally I use either Zeiss T* UV filters or B+W MRC UV filters, no problems so far.

Thanks or your reply.  It was more about the effect of cutting the infra red spectrum twice (on the A7 at sensor level as well as in front of the lens).  The Leica IR/UV filters are pink in colour, and are used because the M8 does some weird colour shift things to certain dark coloured fabrics as it has no Infra Red filter over the sensor.  

 

Anyway, I finally got home and got to try it out (with the VC35mm f1.7 Ultron) after posting my question this morning, and think I'll have to possibly remove the filter when the lens is on the A7 as it was introducing some kind of glare with the filter attached on some shots (depending on angle of light) but was clean and glare free without?? I have never seen any glare with the M8 & the same lens/filter, so something is happening.  I'll have a look at getting some B+W filters, as don't like taking expensive lenses out with the elements exposed... and I'm clumsy at the best of times.

It shouldn't affect your pictures but I'd white balance if at all possible to be sure that it won't.
