Carl Zeiss Sonnar 250mm F/5.6 Superachromat CFE

As far as I know, the Hasselblad V to Nikon F adapter is just a two-part piece of metal without any electronic contacts, so no data is transmitted between the lens and the camera. That’s why the aperture cannot be controlled electronically from the camera, so “P” (Programmed Auto) and “S” (Shutter-Priority Auto) modes will not provide the correct exposure. The exposure metering with Nikon D850 + this adapter + V lens is only available in the “A” (Aperture-Priority Auto) mode. Or you should switch the camera to the “M” (Manual) mode and set the shutter speed manually according both to the ISO selected on your camera and aperture selected on your lens.

I am having two 250mm Zeiss Super Achromatic lens f5.6 and Zeiss 350mm f5.6 with 1.4x converter.
Problem is Hasselblad 503cw,205 fcc and 203 fe cameras are no more produced so I had to buy h6100c two bodies I am using them with h- v cfe converter. I am now shifting towards Nikon d 850 with Zeiss Otus lenses I have seven lenses I want to use my super achromatic lenses with Nikon d 850 I have purchased Novoflex v lenses to nikon converter but my exposures are not very good.
I need some help.
Best regards,
Irfan

Thank for your reply.

Sorry if my reaction was too harsh. It’s just that connotation of “Better alternative” is so strong that it can be misleading to the reader. Thanks for the fine-tuning therefore.

Sigma was marked as “Better alternative” not because of “one cm closer focus and slightly lighter and smaller dimensions” but due to slightly faster speed and slightly larger magnification ratio. We do understand that it is not correct to judge lenses solely on their size, weight and other minor non-optical parameters, especially if they do not differ much among the compared lenses.

I am totally agree with you that the optical performance makes one lens better than another. Unfortunately, our website is not a test lab but just a lens database so we don’t compare the optical performance of lenses. We only compare specifications of lenses. And we do it automatically, just for your convenience. Otherwise, you would have to open several pages dedicated to different lenses and compare the specifications by yourself by switching from one page to another and back.

As a reaction to your comment, I have fine-tuned the comparison algorithm, so it now makes more stringent comparison of zoom lenses. So, your comment made our website better.

LOL, Sigma 28-200mm f/3.5-5.6 DG Macro is ‘Better alternative’ to this Tamron! NO WAY. One cm closer focus and slightly lighter and smaller dimensions will not make a lens a ‘Better alternative’… It’s the optical performance. And in that area The Tamron beats Sigma, hands down!

I think that there is no reason not to trust Metabones. The function of the focal reducer is that it fits the image circle formed by a full-frame lens into the width of the APS-C sensor, which leads to increase in image sharpness and effective lens speed.

If we talk about the deterioration of the “beautiful quality of this lens”, then in what sense? Given the fact that the main application of this lens is to shoot wide-angle scenes (with perspective correction when needed). When combined with focal reducer, this functionality of the lens won’t change at all.

In terms of optical aberrations? When using a focal reducer, they will be more or less the same as on a full-frame camera. I mean lateral chromatic aberrations and distortion in the first place. And they can be easily corrected in post-production. Also, when shooting landscapes or architecture, you usually stop down to f/8 or more, so vignetting and some of the aberrations (longitudinal CAs, spherical aberration, astigmatism, field curvature) at these setting are gone anyway.

In terms of bokeh and recognizable character of the lens? But this wide-angle lens, while being pretty fast, was not designed to provide impressive bokeh and/or recognizable character. This is not a portrait or a fast standard prime lens, after all.

So, I don’t quite understand, as to be honest, what do those people mean by saying that focal reducers would worsen the beautiful quality of this lens.

Thanks a lot for the answer.

The 28mm full frame ported to APS-C becomes a 42mm. Still usable as a shift if you have space. To have nice sober images with less wide angle effect.
However it might be interesting to be able to use it with a speedbooster (I knew the Metabones, but i read that you suggest Kipon). So i could have a 28mm even on APS-C.

I talked about these speedboosters on a forum and many told me that the “focal reducers” would, however, worsen the beautiful quality of this lens (instead on his site Metabones says the opposite, in addition to increasing the brightness he says that it increases the quality of the MTF). Who is right?

There are two types of adapters for mounting Canon FD lenses on SLR cameras: with and without magnifying glass. With glass adapter, the image quality will suffer, so it can’t really be recommended. With glassless adapter, you’ll loose the ability to focus at infinity due to the shorter flange focal distance of the Canon FD mount. The choice is yours but I would not bother at all trying to adapt Canon FD lenses on SLR cameras. The only right way to adapt them is to use a mirrorless camera.

Is there an adaptor that will allow this to work with a Canon Rebel T6s or D80? Would be used only for manual shots.

Schneider-Kreuznach never made dedicated Fujifilm X interchangeable mount for this lens because the lens is designed for 35mm full-frame SLR cameras and Fujifilm mirrorless cameras are APS-C. So, you should use a Nikon F – Fujifilm X mount adapter. I think that Kipon adapters can be safely and easily recommended. Kipon even offers Nikon F (AI) – Fujifilm X focal reducer (speedbooster), so you can get practically the same angle of view with this lens on a Fujifilm APS-C mirrorless camera as on a Nikon 35mm full-frame SLR camera.
