It makes a considerable difference, if you leave a partly shot roll of film
in the camera for any length of time.

No, early Yashica TLRs, pre-Yashica 12, were mostly triplets, and later
models were 4 element Tessar types, although testing indicated that they
were generally inferior to true Tessars or the similar Rokkor [Teeser type]
in the Autocord. All Minolta Autocords use a very nice 4 element design,
but no 6 element. A few of the low volume Japanese TLRs used 5 element
designs which are said to be very good. [Koniflex; Airesflex with the Nikon
contributed Nikkor lens set.]
