Rollei 35 lenshood and filters problem

[daryl_jorud1]

It is recommended to use a lenshood on Rollei 35 with Tessar lens, so I

purchased an original Rollei rigid lenshood, along with original Rollei 24mm

filters. The lenshood fits fine and allows for easy focusing. However, when a

filter is screwed in, reattaching the lenshood causes the filter/focusing ring to

bind against the lenshood, locking the focusing ring. So, I tried yet another of

the original lenshoods, and it caused the same problem. Can't focus the lens

this way. It seems peculiar that original Rollei 35 accessories would be

incompatible with each other. The problem could probably be alleviated by

using a screw-in collapsible rubber lenshood, but the original rigid lenshood

seems to offer far better shading. Anyone else noticed this problem? For

what it's worth, I tried using the original rigid Rollei 35 lenshood on a Rollei

35S. That doesn't work either, as the lenshood binds with the focusing ring,

even without any filters. Suppose I could use a Dremel and grind out the

inside of the lenshood enough for the filter to clear, but there isn't much

material to start with, and a mis-step would destroy it. Any solutions to this

dilemma?

Daryl, never try to fit a Rollei square rigid lens hood on a 2.8/40 Rollei 35 Sonnar, you will break this rare and nice lens hood you were lucky enough to pick several up.

 

I had first thought your problem came from a too large filter barrel (but you use an original Rollei 24mm filter that have a very thin barrel) but on my Rollei 35 T the B+W 24mm filter doesn't cause any problem with the lens hood.

 

So I tried the lens hood on both my Rollei 35 Germany which has an original 24mm Rollei UV filter and then on my Rollei 35 T that has a B+W skylight filter.

 

I didn't notice any problem with the hood, I can focus the lens all along the focusing distances with both the two lenses and the two filters.

 

So I have no idea but I can't help thinking of a bad lens barrel original alignment. When you focus from infinity to 0.9m on a Rollei 35 the end of the lens barrel moves forwards for less than 1 millimeter, so that the space left in the lens hood "window" is large enough.

 

Attached are pictures of both the cameras with their filters and the lens hood pushed on ; looking at them you might find a clue that could explain your problem.<div></div>

The same camera...<div></div>

[nicolas_douez]

Once again...<div></div>

[nicolas_douez]

Now the Rollei 35 T with a B+W skylight filter and the same hood...<div></div>

A close up view...<div></div>

Last one. So sorry I didn't notice anything can could lead me to track of Daryl's problem.

 

Try to fit the hood and the filter on another Rollei 35. It might be helpful.<div></div>

Nicolas, thank you for your replies. I have tried using B+W 24mm filters, and

they do indeed work fine. The B+W filter has a slightly smaller outer diameter

than the original Rollei 24mm filter. In a few hours I will try my luck at posting

a photo showing both filters for comparison, and will list diameter

measurements of the filters, as well as the inside diameter of the mounting rim

side of the lenshood. As you suggested, I have tried different cameras for

mounting lenshood and filter. On Germany R35, Singapore R35, and

Singapore 35T, there was no noticeable difference. Same problem on all of

them. Do you know, was there ever made a rigid lenshood for the 35S?

[nicolas_douez]

They never made a similar lens hood for the 35 S. For the 35 S you must use a B+W rubber lens hood or a metallic lens hood for digicams but these ones are a bit too wide I think - although of a great looking on a chrome 35 S.

 

Then the window that permits to have access to the focusing ring on your two lens hoods might be a bit to narrow (I mean, a factory defect, not impossible at all as it is molded plastic).

 

Rather than using any agressive tool like a dremel I would try to slightly scrape the plastic with a Swiss pocket knife (open at its smallest blade) to get 1mm free more on both sides of the hoods windows. It might be enough. Once done, with superfine silicon abrasive paper (black type, for car paints) you will have to polish the knife blade marks and it will look great.

 

My lens hood showed many cosmetic irregularities in the plastic here and there from a bad molding and I just did so. I didn't have to adjust the lens ring window but I might just have been lucky with my hood.

Here is a photo showing the difference between the Rollei branded filter and a Heliopan filter. Both are 24mm to fit the Tessar equipped Rollei 35 cameras. The outside diameter of the Rollei filter is 28mm, while the Heliopan has a 26mm outside diameter. I may have the problem diagnosed.........with the Rollei hood and Rollei filter, if I squeeze the lateral sides of the lenshood to compress it slightly, the focus ring/filter can be rotated. So, as you suggested, sparingly using an abrasive to remove a small amount of the plastic in the two recessed areas that are intended to allow for the filter might remedy the problem. Will give that a try in the next few days..<div></div>

here's a link to an aftermarket hood for the 35s:

Interesting. I see they also offer a rectangular version......but at triple the price

of the round. Any forum members familiar with these lenshoods?

Its recommended to use a lens shade with every camera and lens except for very wide-angles where they are pretty useless. It makes a detectable difference especially with our classics which have non-multicoated lenses.

<p>Do you have problem using push on square hood on Rollei 35S ? I doubt that a square hood is<br>

appropriate for Rollei 35/35s. What do you do when you rotate the lens to focus ? </p>

<p>IMO, a round hood is much better for Rollei 35s<br>

Only round lens hood is appropriate for Rollei 35S, due to barrel rotation during focusing, rectangular ones are useless</p>
