Lens for copying film with bellows

I just won a bellows in SR mount that I will be using for digital developing my film. Question is, should I buy a M42->SR(MD) adapter and use my 50/1.4 Takumar or buy a Rokkor lens and in that case which one? ...or a third option? I guess low distortion is key and resolution. What would you recommend for copying film?

Hi luage,what will you be copying?slides or negative.I use enlarging lenses as well as Macro lenses,for slides a zoom lens works enabling you to include whole slide,you will have to try different focal lengths until you are satisfied with result,ie.trial and error.

Note that the lens focal length requirement will change based on the digital camera's sensor size, as well as the size of the film format being captured.

Also, don't worry too much about getting a fast lens, as you may need to stop it down anyway to get enough DOF to work around film flatness issues.

I´ve tried some normal 50mm primes for macro shots and most of them delivered crappy results, although being great at "normal" distances (I didn´t try that takumar, some other M42, Olympus and Nikkors). for this reason I´d go for some SLR macro lens or enlarger lens on bellows.

I'll be using it with an APS-C sized sensor and copy both negatives and slides, I currently use a home made tube to put on a 100mm macro lens and for me results are great but I hope the bellows copier unit will make the process more smooth.

Enlarging lens sounds like an appealing solution how do I mount that on the bellows, will it require some sort of DIY adapter thing? And are there better enlarging lenses or can I just use the cheapest available?

Enlarging lenses are certainly an option but there are definitely better and worse enlarging lenses to choose from.

Even SR/M39 is an existing adapter. If you cannot find one, SR/M42 and M42/M39 is a perfect solution for the job. Some Schneider enlarging lenses have M25, but M39/M25 is not difficult to find, I think.
Other interesting enlarging lenses: Janpol 80mm, Meopta Meogon (not Belar), Minolta CE Rokkor.

The good thing about bellows is that you can lash the lens on the front any old how and not have to worry about register distance and hitting infinity Smile

Enlarger lenses look very appealing with flat field and M39->MD adapter exists. Is an APO overkill and how is (C.)E. Rokkor vs EL-Nikkor vs Janpol vs Componon vs Rodagon? Tried to find a Meopta Meogon but couldn't find one.

And let me know if you have a good one that you think I should buy from you Wink

Pentax 1.4 lenses do not have a very flat field and aren't the best choice for copy work. One of the 1.7/1.8 models would be a better choice, or best of all one of the dedicated macro lenses. Pentax did make bellows-specific lenses but they do not turn up all that often.

I can only find Meogon new and they are much more expensive than a used EL-Nikkor.

A good inexpensive lens that is perfect for the task is the Industar macro.

Thanks womble, I think I will go with an enlarger lens as macro lenses tend to be fairly expensive.
