Question about my Rolleiflex Automat K4b

So I've only been into photography and cameras for

about a year now so this might be a weird question but

I've got a Rolleiflex K4b from 1956 and I have a question

about the lens and film. It's a 75mm 3.5 Tessar that has

no T on it. Is this lens coated and if so is it T coating or

something cheaper? Also if it is not coated would color

negative film come out looking alright? I only have shot

black and white through it but I'm thinking about getting

some Portra. Any information would be greatly

appreciated.

Here's a picture of it if that helps.<div></div>

<p>Even if it's not "T star coated" color film will still come out great, just shield the lens if shooting into the sun. The extra coating is mainly to reduce flair. You have a great camera........have fun with it! </p>

<p>Your camera is otherwise known as an MX-EVS (Type II). By the time this camera was made, coated lenses had become standard and so were not identified by a "T". You should get some fine pictures with Portra film, the contrast and saturation will be slightly less than with modern lenses but should be pleasing. You may well find that, like a lot of other people, you prefer the colours you obtain if you shoot the film at half box speed.</p>

<p>You're confusing the "T" coating designation used by Zeiss Jena and (I think) Zeiss Oberkochen in the '40s with the much later "T" designation used for multi-coating. By 1956 ALL Zeiss lenses were coated.</p>
