Time of improvement of the 1102 FTCCFE

Christian Kloumann (Pcp80) & Tetron,

Good morning, would'nt know it, me being a typo King. Thank you for correcting my error. My 350 is a CFE 5.6/350 Sa, not 350 FE. Serial number is sn 8847088.

Sincerely
Richard
 
Q.G.,
Regarding serial numbers: my 110/2 caries the following numbers: ser. 5882190 and a hidden code 22 02. The way I understand it, my lens dates from 1979. Am I right? Thank you, Luka
 
The lenses I used most are the 60mm and the F 110mm.
My CF 60mm is my horsework, I got it 22 years ago used.
I tried to understand how the electrical works for "E" lenses with my 202FA but I havn't any "E" lenses.
Have anyone any idea how "E" lenses comunicate with body ?
Who has an ohnmeter and a "E" lens to mesure the values ?

15 years ago I succed to put a ttl flash meter in a PM viewfinder; perhaps upgrating a CF 60mm to CFE is possible !

Then a CFE-IF 100mm...(?)
 
Isidor,

Depending on the age and construction of the 110 mm lens it is possible to upgrade the F to FE using parts that were available from Hasselblad or Carl Zeiss.
I do not know whether these parts are still available.

F lenses not just the 110 can be upgraded to FE when the lens is of a later series that is provided with lettering by printscreen in stead of the early lenses that have screwed on bands that hold the lettering.

Converting a lens that was never available as "E" lens seems like an adventure with unknown ending to me.
 
The conversion isn't offered anymore.
That may be because they don't have the parts, or because they do not want to. Or both.
So you will have to find an independent mechanic with enough know how, and the necessary parts stil lying around...

I happen to know where large numbers of parts for the 2000 series bodies and lenses ended up.
I bought some lenses where only the glassparts were removed from.
These otherwise complete barrels make a perfect "conversion" possible as they are all from the later "F" models.

Nicest part of this is that these barrels are brandnew.
They were never mounted on a camera nor did they ever have a lens shade fitted.
 
Paul,

With later "F model", you mean "FE" model?

The glass in the first version of the 110 mm lens is a bit different too, making conversion using only a new barrel a bit tricky.

The conversion kits, adding Databus contacts, were discontinued in 2000.
 
Later "F" models are the lenses that have the lettering printed on the barrel as against the early ones that have the lettering on separate metal bands.

With early ones the distance scale for meters is in silver with the later ones it is white.
 
Indeed.

Just to clarify what "a perfect conversion" means: those barrels alone will not make a conversion from non-Databus F to Databus FE lenses possible. You would of course need the (discontinued) circuit boards for that too.
 
Hi Q.G.,

> If so, those would be "FE" models, not "F" models after all.

I thought there were earlier F models and later F models, and the later F models could be converted to FE (but that does not make them FE models until after the conversion), and the earlier ones could not. This what I believed he was talking about.

Was his distinction:

“Later "F" models are the lenses that have the lettering printed on the barrel as against the early ones that have the lettering on separate metal bands.

With early ones the distance scale for meters is in silver with the later ones it is white.”

incorrect for the two F models?

Hi Austin,

I'll retrace our steps:
This ancient thread was revived by Isidor inquiring about the workings of the "E" in a lens' designation.
Paul answered, pointing out the existence of the conversion kits that would make FE lenses out of F lenses.
(These kits were discontinued/ran out in 2000.)

Paul later also mentioned that he has a bunch of empty lens barrels that could turn an old F lens into a newer F (! I asked: not FE) lens.
(That may or may not be possible, depending on the glass that has to go inside. But that's another issue - see below).
But since they are said to be (newer) F barrels, not - as Wilko suggested - FE barrels, they don't turn F lenses into FE lenses.

Paul is correct, of course, about the scales.

Will the old F glass still fit the newer F barrel?
Maybe. If the change of barrel did not also involve a change of the internal mount.
 
Of course I have the old version of the 110F ! I cann imagine the improvement for flare at 2.0 with the baffle add.
 
Hi Q.G.,

Thanks for the recap. Some interesting info there.

But, to my question, it is only the late "F" models that could have been converted, and Paul said he had "later "F" models", and your reply was asking if he meant FE...and from what I read, it appeared he meant later F as he said, and I was trying to get clarification as to why you thought he meant FE.

Nothing to do with the later comment in that thread about circuit boards...

Regards,

Austin
 
I bought quite a large selection of glassless lenses:
They are CFE, CFi, F and FE models from 40 to 350 mm.

Sofar I had a very clean 150F changed into an as new 150FE.
Same goes for a 50 mm F uprated to FE spec.
The 110 I have is original FE so nothing altered.
The last to be converted is a 250F that will become a 250FE.

With the price of spares and the uncertain future of parts supply
I thought it was a good idea to buy this lot.
The improved flashconnector is more expansive than a glassless lens.
 
This is a multi-tier message in regards to the older F lenses.

Regarding the 110mm, what were the improvements to the 110mm focal length and exactly how did they differ in its evolution to the final version? I have an earlier 110mm in 588 range and a recently acquired 110mm in the 694 range along with an Canon EOS adapter. Both do not have the square baffling in the rear.

To Paul Kirchhoff, can any of the older 50mm F and 150mm F be converted over the newer FE style of lenses? Or is it limited to the ongoing changes that might had occurred within F lens improvement like the 110mm?

Did the 50mm and 150mm also undergo the improvements like the 110mm and what were they? Did it change the optical design?

Evan,

As far as I know only the 110 underwent some changes that occured near the end of production.

F Lenses that were of the later design as far as the barrel goes can be converted by fitting the electronics and contacts from the FE series. The later design has lettering by screen method rather than the early lenses that had removable bands with lettering fitted to the barrel.
To convert you need a kit that is no longer supplied.
Of course some workshops might still have the parts needed to convert.
The easiest conversion is by finding FE lenses with missing glass parts.
I have rebuilt a couple of those lenses that way.
The lensnumber from an older lens is the only way that shows it concerns a lens built up with parts from an F lens without electronics.
