f3p5 Posted May 14, 2015 Share #143 Posted May 14, 2015 (edited) My heliopan 46mm filter can be screwed into the 7.5mm sleeve. Fits perfectly. This is to prove the 7.5mm sleeve has 46mmx0.75 female thread. Welcome, dear visitor!

f3p5 Posted May 14, 2015 Share #144 Posted May 14, 2015 (edited) My Telyt 280 4.8 V3 lens head can be inserted into but won't be screwed onto my Leica Bellow II front flange directly. The lens head and its focusing unit uses a thread which diameter is smaller than 63.9mm of the Leica Bellow II front flange thread and their thread pitches are also different. I left a small gap between the lens head and the Bellow II front flange to let you see they are "perfect" to look/match from outside but their threads won't be engaged. Welcome, dear visitor!

f3p5 Posted May 14, 2015 Share #145 Posted May 14, 2015 (edited) Can someone post a picture of the Telyt 280 4.8 lens head which can be screwed into the Leica Bellow II front flange directly? Just the lens head only. Does it have the detachable 7.5mm sleeve as on my Telyt 280 4.8 lens head? Thanks. Edited May 14, 2015 by f3p5 Link to post Share on other sites More sharing options...

As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Coupling is perfect and solid, no doubt is the same thread : it must be observed, however, that this kind of attachment has a very limited focus throw... I just checked... you can focus to infinity (of course, with a Visoflex II/III in the middle... I used the Novoflex LEM/VIS, which has the same length) , but the bellows is not far from its full extension... fully extended it focuses down to 5 meters or so... no less (I didn' make precise measurements tonight) : all in all a set that has little practical usage... onto a tripod, maybe if one gets accustomed to operate quickly on the bellows focusing rail (which is rather smooth) can be a decent setup for some sport/wildlife action shooting from fixed position... My conclusion : Telyt 280 V3 lensheads are NOT all of the same kind : yours is "old" (first batch) and cannot fit drectly the bellows... mine is "last batch" and fits directly the bellows... from the previous posts of this longtime thread seems the other 280V3 have the head like mine , other like yours... could be interesting to disover when this modification did occur... V3 was made in small batches (and my one, in particular, seems to be from a batch of lensheads only) and from the items in the hands of forum member it could be not difficult to determine this little "divide"...

f3p5 Posted May 14, 2015 Share #152 Posted May 14, 2015 So 14138 is for Televit use only(cannot use on Bellow II). Is that right? Your lens head shown in #147 is the same lens head in #146. So the later production of V3 has 63.9mm thread and the smaller 46mm thread . Link to post Share on other sites More sharing options...
f3p5 Posted May 14, 2015 Share #153 Posted May 14, 2015 The 46mmx0.75 thread is interesting, so it open the door to adapt this lens to be used on other cameras or bellow systems. Link to post Share on other sites More sharing options...

f3p5 Posted May 15, 2015 Share #155 Posted May 15, 2015 The aperture ring on my first batch of V3 and your last batch of V3 of this Telyt 280 4.8 lens looks differently. I don't have a caliper to measure but use my ruler, the larger thread of this lens is about 63mmx0.75 and the one on your last batch seems to be 63.9mm x1.0.

luigi bertolotti Posted May 15, 2015 Share #156 Posted May 15, 2015 So 14138 is for Televit use only(cannot use on Bellow II). Is that right? RIGHT Your lens head shown in #147 is the same lens head in #146. So the later production of V3 has 63.9mm thread and the smaller 46mm thread . EXACTLY .

f3p5 Posted May 15, 2015 Share #157 Posted May 15, 2015 It is clear now 14138 is for Televit use only. Is 14138 for Telyt 280 4.8 V3 late production with the 63.9mm larger thread only? How my early production Telyt 280 4.8 V3 (and V2) can be connected to Televit? Thanks. Link to post Share on other sites More sharing options...

How my early production Telyt 280 4.8 V3 (and V2) can be connected to Televit? Thanks. The 280 V2 CAN be mounted on Televit, unscrewing a collar and mounting the 14138 instead (see post #112 -113-114 in this thread) : of this I have direct evidence from my 280 V2... don't dare to say anything about the 1st series of V3... by logic, it could not be mounted on a Televit (14 138 engages onto the famous 63.9 mm thread... which from your evidence, and from others' too, is different in the V3s of the first series) 1 Link to post Share on other sites More sharing options...

f3p5 Posted May 27, 2015 Share #160 Posted May 27, 2015 (edited) Bomber! There might be different version of 14138. Recently I bought a Telyt 280/4.8 V2 SN:1919002xx with 14138 (I believe). This 14138 ring can be screwed in the Telyt 280 V2 lens head SN:1919002xx with no surprise. Surprisely, it (14138) can also be screwed in my Telyt 280mm/f4.8 V3 (first batch of production) SN:27138xx lens head. I am pretty sure that my Telyt 280mm/f4.8 V2 and V3 lens heads have the same thread, about 63mmx0.75. I do not have any Televit to test my 14138. I will post some pictures later.
