mark_jones4 Posted November 8, 2003 Share Posted November 8, 2003 Is it possible for the user to decouple the shutter/aperture interlock on the Rolleiflex 3.5F Type 1? If so, how do I do it? Mark Jones Link to comment Share on other sites More sharing options...
witold_grabiec Posted November 8, 2003 Share Posted November 8, 2003 My Rollei has an appointment with Harry, but the shutter adjustment wheel has a little tab underneath it. It's hardly protruding but you can press it in with your thumb and than turn the shutter as required. You turn as you press. This allows for any shutter/aperture combination. Hope this helps.

conrad_poulin Posted November 9, 2003 Share Posted November 9, 2003 Mark: All F models will have an "F" in front of the serial number. The 3.5 F1 does not have shutter aperture interlock. Serial numbers on the F1 start at 2,200,000 and run up to 2,229,999. If your camera has a Rollei F&H logo on the top of the hood and a slotted dedent on the aperture thumbwheel, and evs values on the shutter dial you probubly have a later Model E. If this is the case you ingage or disingage the interlock by pressing the slotted detent on the aperture wheel in and turning. I hope this helps!

witold_grabiec Posted November 9, 2003 Share Posted November 9, 2003 Nope, I have the 3.5 F and it DOES have the aperture shutter interlock. The F models have the light meter built in, and the shutter/aperture uncoupling is done as I described above. Link to comment Share on other sites More sharing options...
witold_grabiec Posted November 9, 2003 Share Posted November 9, 2003 Just to clarify this interlock issue. I've looked through some Rollei literature and the 3.5 F Model 1 came with shutter/aperture interlock and apparently from Model 2 on (or from 1960) interlock was no longer available, or so it seems from the pics of each. Release tab is located under the left thumb wheel ( while holding camera in normal shooting position), and I believe it actually operates the diaphragm.

siu_fai_au1 Posted November 10, 2003 Share Posted November 10, 2003 There is no way to decouple the interlock except when changing aperture. The serial number of the first model does NOT start with the 3,5F. These model indications are later creations. My first model 2,8F and 3,5E3 both have these model indications but my 1st model F (the one with the interlock) does not and just shows 22024xx. The first model is the only F model that has this interlock. The interlock is removed from the 2nd model. 3rd and later on models have a different Compur shutter.

david_seto1 Posted November 10, 2003 Share Posted November 10, 2003 I have used 3.5F models with and without the interlock. IMHO I find the interlock annoying as proberly the original thread poster does. My question would be is it possible for a technician to internaly remove any interlock links such that the aperture and shutter speeds are fully independent ? regards David.

mark_jones4 Posted November 10, 2003 Author Share Posted November 10, 2003 Many thanks for your contributions everyone. David is right - I find the interlock annoying. I'll be interested in any responses to his question. Mark Jones Link to comment Share on other sites More sharing options...
conrad_poulin Posted November 10, 2003 Share Posted November 10, 2003 I responded earlier and suggested you may have a later E model. While looking through Artur Evens Rollei Guide noticed I somthing interesting. The 3.5F type 1 was produced from 1959-1960 while the 3.5E3 was produced from 1962-1965. The E3 came with no meter but a T type meter could be retrofitted later. I am curious, is the book in error? or are many E3 models with meters refered to as F1 models? Also note that the E3 has the interlock. Link to comment Share on other sites More sharing options...
siu_fai_au1 Posted November 11, 2003 Share Posted November 11, 2003 Conrad, the F1 and E3 are different models (I have them both). The original F1 was the first model with the coupled Gossen meter. Compur designed a special shutter with a extra set of gears around the shutter to transmit the set EV to the meter. The F2 model has this same shutter but with the interlock removed. So technically, it is possible to remove the interlock but I have no idea what kind of modifications this transformation from F1 to F2 involves. F&H was not satisfied with this special shutter with the planetary gears. Due to the extra gears, the shutter was larger than the standard 00 shutter, hence the increased lens distance from 43mm (E, E2) to 45mm (F)). They need to find an alternative to have the meter coupling included for the 2.8F (this is the reason why the 2.8F was introduced several years later than the 3.5F1). The solution was a extra set of gears outside the shutter and under the aperture dial. This extra gear allows the use of the standard Compur shutter and to be used for the 2.8 model. The 3.5E3 was a modified F3 without the EV transmitter under the aperture dial but with EVS. So the E3 is the F3 without the meter coupling but with a EVS system that can be disengaged. The E2 is the E model with a removable WLF. Internally, the E/E2 and E3 are quite different. The difference in shutters (E/E2, F1/F2 and F3/E3) is the reason why the selftimer handle/knob are located differently. Siu Fai Link to comment Share on other sites More sharing options...
conrad_poulin Posted November 11, 2003 Share Posted November 11, 2003 Thanks ! Siu. I am always interested in anything Rolleiflex. Recomended books on Rollei and other classics also. Link to comment Share on other sites More sharing options...
siu_fai_au1 Posted November 12, 2003 Share Posted November 12, 2003 The best reference books I have seen are the Rollei Reports (1-5) from Claus Prochnow: http://www.rollei-report.com/html/rollei-bucher.html The books are written in German but there is an Engelish text translation of the Report 1. He is working on the translations of the others. Siu Fai Link to comment Share on other sites More sharing options...
robert gordon Posted May 21, 2004 Share Posted May 21, 2004 I have a 3.5F (taking lens serial # Nr 2932799). There is no tab on either the lens or apeture wheel that allows me to release the interlock. Consequently, when shooting at 1/500th I am unable to use an apeture small than f/8. Any advice? Thank you. Link to comment Share on other sites More sharing options...
