Topcon Lens Mismatch

[User_502260]

<p>Yesterday I picked up a 58mm f/1.8 RE Topcor. It's the chrome (aluminum) model with the black rubber coated focusing ring. I put it on my Re Super and it fit perfectly. Then I tried to put it on my RE200. It would not fit. the RE200 was originally sold with a 55/1.7, a 50/1.8 or a 50/1.4. The last two were GN lenses. Mine came with the 55/1.7. It looks like part of the 58/1.4 protrudes too far into the mount and touches the bottom edge of the mirror. The manual for the RE200 does not mention this incompatibility. The 55/1.7 fits the RE Super with no problems. Later today I am expecting a Topcon D-1 with a 58/1.8 RE Topcor. It will be interesting to see whether that lens fits the RE200. </p>

<p>The 58/1.8 RE Topcor arrived. It fits both the RE Super and the RE200. It has some scratches on the front element. I will need to shoot some test film and see the results. </p>

<p>Any chance the glue holding the mirror in place has loosened and allowed the mirror on the RE200 to slide down a bit? I don't know anything about Topcons, but most manufacturers will warn about incompatible lenses in the manual.</p>

<p>The mirror in the RE200 can't slide down because it is held in place by what look like metal brackets. I have used the RE200 and it seems to be working properly. I'm not sure Topcon even made the RE200 or RE300 models. They were sold under more than one name. </p>

<p>As I recall, the lenses between the two series of cameras are NOT interchangeable.</p>

<p>You are thinking of the Topcon Unirex (leaf shutter) and Topcon IC-1 (focal plan shutter) models which took the UV Topcor series of lenses which had a completely different mount from the RE Topcors. The reason the RE200 and RE300 cameras had RE in their names was that they continued the mount of the earlier RE Super cameras. The 58/1.8 RE Topcor fits the RE200 and the RE Super. The 58/1.4 RE Topcor fits the RE Super but not the RE200. The later 55/1.7 RE Topcor fits both cameras. </p>

<p>Yikes, same for me. The bottom of the mirror box is too close to the lens mount. It hits the protective tab on the rear of the 58/1.4 lens. Total incompetence. The RE200 is a third-party K-mount camera that Topcon had modified to RE-Auto mount.<br>

The tab on the back of the lens mount prevents you from scratching the rear element when you put the lens down on a flat surface. There's a smaller version on the 28/2.8, 50/1.4, and 50/1.8 lenses, which should be no problem.<br>

Another reason not to like the RE200 and RE300 cameras, as the 58/1.4 is a great lens.</p>

It will, the 58/1.4 has a mount protector  that interferes on the re200. Topcon did not make that camera, sub contractor Cima kogaku did.
