Title: Hasselblad 40mm f/4 Distagon versions
Post by: Brian Hirschfeld on January 19, 2014, 05:29:06 pm
Hello,

I am looking to upgrade my 503CW lens kit. Currently I have the 80mm CF, and the 120mm CFi and I am looking to get an 80mm CFE (purely for aesthetic and focusing reasons), and the 50mm f/4 CFi which rounds out to a nice wide-angle. I am also considering picking up a 40mm Distagon. I plan to shoot these lenses almost exclusively with black and white film and possibly some color film. I have no plans to buy or rent a digital back for this system, so if I were to purchase a 40mm (and thoughts on 40mm as a 6x6 focal length are welcome) would I notice any substantial differences between, the C, CF, CF T* FLE, and CFi (CFe?) versions of this lens for shooting film? Thanks,

Best,
BH

i had (still have but dont use) the FLE floating element version and used to shoot a lot of jobs on in plus a fair bit of black and white, it was a good lens and i didn't feel it was inferior in quality to the 80 and 120 i also used, a colleague had the older non floating version and when he went digital he felt the need to upgrade to FLE which he still uses with a p45. a lot of people seemed to buy the 50 and rent the 40 when they needed it as a was an expensive lens in the u.k.
no idea what the latest incarnation is like on film though.

The CF40 FLE and newer is the way to go.

I think the order that Hasselblad released them started with the origianl 40mm C (compur or combo-I think) that the first and largest physically of all the 40mms lenses. So-so performer as I recall, not even close to the 38 Biogon. The FLE is a modern redesign and has the T* coating that makes this lens superb (and in the ballpark as the 38mm) along with the close-focusing adjustment to get even more IQ from this design. Newer versions (CFi) add some electronic connections, maybe some updated shutter (spring) components, cosmetics and perhaps a bit different glass (a couple of lenses went lead-free and Hasselblad crowed about this "Ecoglass"), but not much else if I remember properly. The T* coatings began at the end of the C lens series sometime in the 1970s or early 1980s.

The key thing with the "V" lenses is getting any of the wonderful Zeiss lenses with the T* coating for the most crisp image quality and least flare. You also stand a better chance of getting your lens repaired with these more durable (and accurate) shutters since the CF and newer lenses came with the updated Prontor shutters and modern lubes.

Hi,

There is late version of the Distagon 40 called IF CFE, I don't own it but it seems from the MTF curves it is much better than the older FLE-s. I have a CF FLE and I am pretty sure the IF version is better, but it is rare and expensive.


Here are data sheets for all V series Zeiss lenses: http://www.hasselbladhistorical.eu/HW/HWLds.aspx

Your best bet is the CF/Cfi 40 FLE, the IF version while being incredibly sharp (and the better option for digital) has some moustache distortion that is hard to remove. A 'better' alternative to the 40 FLE is a 903 SWC - but it's not as user friendly.

Here are a couple of samples from my Distagon 40 CF FLE

There are opinions that I am not making the best of my equipment, but this is about what I achieve. I have not seen many raw images from the Distagon 40, except my own, so I cannot judge.

Raw images are here:

The CF 40 FLE has a few bad problems, in my view. There is a hefty curvature of field, edges bending inward, also chromatic aberration is complex and LR5 is not really good fixing it, Capture One makes a better job on that.

The field curvature can sometimes help, as it often extends depth into the foreground.

I often use this lens at f/11 to f/16, but the center is very sharp at f/8. The enclosed MTF data (from Zeiss) shows how the lens performs.
