Will 120mm Macro Planar CF give me 1:1 magnification when attached to a fullframe DSLR via adapter?

[vice_versa]

<p>Hello!<br>

I'm looking into a purchase of Zeiss 120mm Macro Planar for Hasselblad 501cm. I would also love to use it with my Canon 6D as macro lens. Will it give me a 1:1 magnification? If not - how can I calculate the actual ratio I can get?<br>

Thank you in advance!</p>

<p>It'll give you the same magnification no matter what camera you mount it on (max. 1:4.5, I think?). What changes with format

is the proportion of your image the subject will cover.<br>

<p>Yes, it will. 1:1 magnification means that 1 mm on the subject being photographed is imaged as 1 mm on the sensor/film. You can have different sized sensors/film, but 1 mm across them is always 1 mm!</p>

<p>Not without a bellows or extension tubes it won't. This so-called macro lens only focuses to 0.8 metres without further extension. Not just that, but it's only optically optimised down to 1:2 (half-size), so I'm really not sure how it justifies its 'macro' epithet.</p>

<p>As Ray says, the reproduction ratio will stay the same (but at 1:4.5) regardless of which camera it's fitted to. Personally I'd get a proper macro lens for the 6D - one that focuses to 1:1 without further accessories - and forget about doing macro on the 'blad. Smaller formats have the advantage of giving greater depth-of-field for a given subject size within the frame.</p>

<p>Zeiss still have a habit of doing that - witness the Zeiss Macro Planar 50mm and 100mms (ZE/ZF).</p>

<p>Thanks for replies everyone. I'm totally ok with 1:2 ratio, since I'm going to use it for a very specific application and not going to shoot macro in "normal" sense.</p>

<p>What extention tube would I need to achieve 1:2?</p>

[Jochen_S]

<p>A tad less than 60mm. - Exactly 60mm would grant 1:2 @ infinity engraving.</p>

<p>Thank you, this makes it a less desireable investment. It's already 1 stop darker than Canon 100/2.8 macro and with the added extention tubes the bellows factor will be just enormous. </p>

<p>V V, if you want to do macro with a 'Blad, get the 135mm macro & the auto bellows. It's a true "macro" lens. Early one are marked S-Planar, later ones are Makro-Planar.</p>

Hi, I would like to know for 120mm Macro Planar CF? By inserting the Hasselblad extension tube 32 to the macro range can be increased to 1:2. if inserting extension tube 32 + 16 or 32 + 56 or 32 + 32 will the macro range can be increased to 1:1 ? Thank you
