What diameter and filter size for Rodenstock 150s?

[ruslan safin]

Hello, friends! I bought 100 sheets of Ilford Delta 100. Now I need a

red filter but don't know what size I should get. What are the

diameter and filter size for Rodenstock 150s and Rodenstock 90? Thank

you in advance!

Rusla,

<p>

The easiest way to find this info is to go to Goggle and type in the word "Rodenstock."

It'll link you up with sites where you can find the answer to your question.

However, here is a link for you to follow...

Hope this helps.

The Rodenstock APO Sironar 150 S weighs 230 grams, takes 49mm filters, and covers 231mm.

 

You might want to try using a polarizer instead of a red filter. It will give nice deep skies, without losing detail in other colors and in the shadows. Or, if you want very deep sky values, a polarizer plus a yellow or orange filter. With a polarizer, you can rotate it to select the depth that you want.

[ken_lee11]

Here is an example using a polarizer alone. A red filter would have given harsh sky and it would have obscured the luminosity of the shadows.

THANK YOU! THANK YOU! I know now. And is it true that any filter (small format lenses or medium format lenses) would fit Rodenstock without a problem if it is 49 mm or do i need a special large format lens filter?

Go to the following site, click on 4x5 lenses and you'll find a wealth of data - including filter sizes, coverage, weight, etc for almost every large format lens currently produced.

To be sure you get the right size, you have to exactly match the name of the lens. Rodenstock currently makes two lenses in each of these focal lengths and has made others in the past.

 

Both current 150 mm Rodenstocks, the Apo-Sironar-N and Apo-Sironar-S, take 49 mm filters. Some discontinued 150 mm Rodenstocks took different size filters. The 90 mm f6.8 Grandagon-N takes a 67 mm filter, the f4.5 version a 82 mm filter.

 

Modern practice has standardized on one filter thread for each filter diameter, so all modern 49 mm filters have a 0.75 mm metric thread. So if you have a Rodenstock lens that takes a 49 mm thread, any 49 mm filter should fit -- you don't need a special LF filter. Many decades ago this wasn't true -- there could be two different filter threads for the same filter diameter.

 

If you want to use a filter on both of your lenses, one possibility is to buy just the large size and to use a step-up ring on the lens with the smaller filter diameter. However, 49 to 67 mm is a big step and it might be tough to find a step-up ring that makes this large of a step. Another possibility would be to do make the jump using two step-up rings.

I have a B&H (www.bhphotovideo.com) catalogue handy in which they offer step up rings for 49mm to 67mm and, for that matter, to 72mm and 77mm. Price is US$6.95.

You might also consider using a gel filter (Kodak/Wratten, Lee, Cokin) with a filter holder that will fit both lenses. These filters come in various sizes, but a 4" x 4" will cover even a 90mm SA XL (100mm).

[leonard_evens]

I echo the suggestion that you consider an alternative. I use the inexpensive Lee GelSnap holder---with rubber band---and 4 x 4 polyester filters with Rodenstock 150, 90, and 75 mm lenses. Unfortunately, this won't work with polarizing filters.

Thank you, people!:)

With my Rodenstock lenses, the filter size is embossed on the inside of the lens caps. 'Course, if you've lost the lenscaps, or have replacements, this information may not be all that helpful.

"the filter size is embossed on the inside of the lens caps"

 

You sure that is the filter size and not the diameter of the lens?

[ken_miller4]

In the case of my lenses, it's the filter sizes. Either that, or a lucky coincidence :-)

 

For example, my 305 G-Claron, 110 SSXL have 67 on the inside of the lens cap, and the 150mm Sinonar has 49. So my Rodenstock and Schneider lens caps match the filter ring size; not sure about my Fuji lens tho.

[ken_miller4]

Oops, my mistake. The number on the inside of the lens cap is indeed the outside diameter of the element.

 

Funny how memory plays tricks on you.
