90mm apo-symmar for close-up work

[vania_plemiannikov]

<p></p>

<p >Hi all,</p>

<p >I own a Rollei 6008i2 and I’m trying to find the appropriate lense I need for close-up work. I’m having a very hard time dealing with macro numbers ratios, magnification, etc. I read countless articles on this forum and tried to find books on the subject but I still don’t have a clue about what this all means…</p>

<p >To make a long story short, what I’m looking for is a macro lense that will allow me to fill my 6x6cm with either</p>

<p >1. real size subject, 6cm long (1 :1 that part I get !). That would be on seldom, which means I could deal with extension tube(s) for that (I own a 9 and a 17cm tubes).</p>

<p >2. about 12cm subject (1 :2 that part I get also !!!) on a very regular basis which means I would like to achieve this without tubes and at a reasonable distance from the subject.</p>

<p >3. subjects about 14-24cm long (that would be 1:?-1 :? I dont understand how to calculate this… duh !). I guess this is less of a problem but still…</p>

<p >One of my main concern is not to be to close to the subject so I won’t cast a shadow. I’m guessing more than 1 meter away. But… I hate long lenses and how they flatten perspective.</p>

<p >So I’m hoping the 90mm Apo-Symmar is right for me but the investment is so huge, even on ebay, that I want to be sure it fits my needs.</p>

<p >Could people that own one give me feed back on close-up work, please ? What extension tube or tubes do you need to achieve 1:1 magnification ? How close to the subject do you have to be ? How confortable is it to shoot at 1 :2 ? How does it work for close-up portraits ?</p>

<p >And to the math guys out there, how do I calculate how big an object can be in order to fill my 6x6 neg for a given lense ??? and distance ???</p>

<p >Thank you for your help.</p>

<p >V.P.</p>

<p >P.S. What's the font used on these forums? I love it!</p>

<p>Hi Vania,</p>

<p>I have been using this lens extensively on 6008i, 6008af and Hy6 and I have a full callibration of this lens.</p>

<p>Hope the following information would be helpful to you:</p>

<p>This lens uses a filter size of 95mm</p>

<p>As it has a wide and long built-in hood, when you come to 1:1 your subject will be around 100mm in front of your lens.</p>

I am sorry if I have included too many intermediate steps but editting the table is more tedious than I thought.<br>

The other lens that you may consider is the 150 macro, but it needs a long extension of 300 mm (full bellow plus 67 and 34 extension tubes to go to 1:1) So the 90 should best suit your purpose, and give you arguably the best performance that money can buy. <br>

Cheers,</p>

<p>Tak</p>

[tak_l._poon1]

<p>PS you do not need 9 or 17 mm extension tubes. One 34 mm and one 67 mm tube will be the best companion of this lens. Tak</p>

[tak_l._poon1]

<p>I guess the font comes with Windows vista and 7 and it is called Constantia. Tak</p>

[tak_l._poon1]

<p>To summarise :</p>

<p>6 cm subject: extension tube 67, exposure compensation 2 stops.<br>

12 cm subject: extension tube 34, exposure compensation 1 stop.<br>

14 to 24 cm subject: no extension tube needed. exposure compensation 0 - 1/3 stop.</p>

<p>Cheers,</p>

<p>I am sorry for the fragmented answers. This lens is not for close-up portraits. I would suggest you use a longer lens like the 110 or 120 or 80mm xenotar + 1.4x longar. Tak</p>

<p>tak - <br>

I got the 1.4 telextender, and am delighted to use it with the 180 lens, but was disappointed that it didn't work with the 90 mm. Do you know if it will work with the 80's (f. 2, 2.8 Schneiders, manual or auto focus)? Or other lenses? Thanks, <br>

Geoff</p>

 

[tak_l._poon1]

<p>There are 2 versions of the 1.4x longar (or 3 ?, with the oldest being one for non-PQ lenses? ). They are the 6000 and the AF. The posterior element of the 90mm macro is protruding too long and definitely will damage the 1.4x. It works with the 300mm, and the 80 xenotars (both f/2 and f/2.8). Only the AF will retain autofocus function. It also work with the 150mm macro symmar with a 67mm extension tube in between. It doesn't work with 80 planar for the same reasson as the 90 macro. As I do not have other zeiss lenses I do not whether it work with them or not. Cheers. Tak</p>

[geoffrey goldberg]

<p>Thanks for this. Geoff</p>

[vania_plemiannikov]

<p>Wow!!! thanks Tak for the such precise answers... I couldn't have hoped for better! I'm sorry, I'm just seeing that my post has been answered, for some reason I didn't get email notification. But thank you very much for the time you took.<br>

Just one question though. In your first post when you say that at 1:1 it will be 10 cm away from the lense do you mean in front of the glass, or the hood?<br>

Thanks alot<br>

Vania</p>

[tak_l._poon1]

<p>I mean in front of the hood. Tak</p>
