Rollei Filter help.

Hello,
I use a yellow and H1 filter on a Bay 11 Rolleiflex, when not wanting to lose an F stop I swap them around. My eyesight at the age of sixty is getting worse and when the yellow is on the viewing lens in low light, focusing is far from easy.
So what are the filter names/numbers that I should be looking for. I have seen UV's up for sale but not seen a skylight yet. Just a plain clear piece of protective glass is what I am in need of.
Thank you in advance for any help.
Cheers,
James.
 
I don't quite understand. You don't put any filters on the viewing lens. It's only needed on the lens that does the actual photography. The only occasion in which you may want to put a filter on is the polarizer, in order to determine its effects. But then you need to transfer it to the taking lens for the actual picture.

Rollei Bay II UV lenses are not hard to find on ebay.
 
I'm not quite sure what you are seeking, either.

If you want another clear filter to protect the viewing lens, you could just get another Rollei H-1 haze filter. As I recall, this is a standard UV filter. The Rollei "UV" filter is a strong UV filter, for at the beach or high in the mountains, and it blocks about 1/3 stop of light. So, the H-1 is more likely what you want.

If you want a less expensive filter to protect the viewing lens, here is a Hoya UV filter on eBay:

If you're looking for something else, you may need to explain further.

Thanks, it is for lens protection. I can not understand why anyone would not use a clear filter for protection. My fingerprints never fail to get on the glass, so I am constantly cleaning it.
What is an H1 filter, is it just plain glass ?
 
I use a UV/haze filter for protection of my viewing lenses, also. Any UV, haze, or skylight filter would work (but not a "strong UV" filter like the Rollei UV).

See my post, above, for a description of the Rollei H-1 and UV filters. You would want the H-1 (haze filter), not the UV which would cause a loss of 1/3 stop of light. I also included a link for a less expensive Hoya UV filter on eBay.

I have seen some very cheap clear filters in plastic mounts in Bay-I size, but last time I checked on eBay I didn't see them in Bay-II. I wouldn't trust the optical quality of such filters for use on the taking lens, but they should be just right for protecting the viewing lens, if you can find one.

EDIT: Here is a really good deal on eBay, for a new off-brand skylight filter in Bay-II:

Thank you for the informative reply there CMur12. I will keep an eye out for another H1 from now on.
I wonder if the glass in the viewing lens is the same soft variety as the taking lens ?
Cheers,
James.
 
I use two matched B+W MRC UV filters in Bay 2 size: one on the taking lens, and one on the viewing lens. That way, I minimize the chances that the filter glass will affect lens focus, as both lenses have the identical piece of glass. B+W no longer makes the Bay filter sizes, but Heliopan still does, at heart attack inducing prices.

For the ultimate in protection, I use two hoods on my Rolleiflex 3.5F. You can't do this on the 2.8F models (no space). You can do this on the Bay 1 filter size cameras. I posted this many years ago, and received a gigantic yawn from the photo community.

The camera in the article shows a Rollei UV filter on the upper lens, and the B+W UV filter on the lower lens. That camera, along with the protection filters and hoods has been sold. I do have another one with the all B+W filter setup (not for sale).:D
 
Robert, I don't recall seeing your post. And already have the two hoods mentioned.
Good idea and thanks for sharing.

Mamiya apparently recognized the value of shading the viewing lens, as well. For each of my 135mm and 180mm lenses, Mamiya provided a lens hood in the form of a rectangular box that shields both taking and viewing lenses. The shorter lenses, however, only had lens hoods for the taking lens.
