Thanks a bunch, I've always thought that using an extension tube or bellow increase the F stop, I must have gotten it mixed up with something else...


Extension does cause light loss/increases the F stop. But the loss is the same whether it is through bellows/extension tubes/helical focussing in the lens itself. Lenses with internal focussing are an exception.

Nikkor 55/3.5 micro - you can get it very cheaply these days and it is one of the sharpest made. Else the 50/2.8 el nikkor on a bellows - extreme quality for peanuts.

The Micro Nikkor 55mm f/3.5 is great. Other option is M42 lens like Tak 50mm 1.4 mounted in a Nikon body.

Shot made this weekend Micro at 3.5 han held



Tak 55mm 1.4 example at 1.4 hand held

Does the Nikkor 55/3.5 micro goes 1:1 without tube?

I have tried the reverse macro with a 50mm, but the DOF is too narrow for me to hand held, so I am getting tubes to be used with my 50/1.4. If it doesn't work either, I will try to get dedicated macro... Embarassed

Thanks for all your suggestions, much appreciated.

Hi Aleksander,
I guess my Micro 55 3.5 goes...at least the inscription on the lens tells me so.
If I am wrong, please let me know.



I am sory the crapy image I just do it in a hurry to show you.

The Canon FD Macro lens is very cheap these days because it won't focus to infinity on an EOS except when used with a corrective optical adapter. With a plain FD-EOS mount adapter, though, it does work in its macro range on an EOS. The images it produces are outstanding. On full frame the lens goes down to 1:2 but with the 1.6 crop factor on my 7D it will reach down to nearly 1:1.

@Fernando,

AFAIK, no manual focus 55 mm Micro-Nikkors go to 1:1 without a tube, other than the oldest 5.5cm/f3.5 (photo at http://www.photosynthesis.co.nz/nikon/f55b.jpg.

The engravings on your lens barrel show the reproduction ratios (with a tube if bigger than 1:2) and focused distances.

I´ve got a little older aperture compensating version, and it shows the corresponding aperture values as well.

At around 1:1 the DOF will be very limited. Extension tubes and dedicated macro lenses, however will not improve DOF when using same effective apeture.

FWIW, 1977

I can vouch for the preset Macro Takumar 50/4 - goes to 1:1 and gives excellent results. The Micro Nikkor 3.5 is also superb, using the tube allows 1:1.

Are we talking about magnification factor on the film/sensor?

I get 1:2 magnification on both 1.6 crop camera and full frame sensor/film, using same lens. at 1:2.

That's a good question so I did a quick check. The sensor on the 7D is 22.3mm wide. At 1:2 extension the 50mm Canon Macro fills the frame with a 32mm wide object. I believe that's just about 1:1.5. For full 1:1 an extension tube or other accessory would be needed.

There was a Vivitar/Soligor/others? 55mm f2.8 macro that comes with a 1:1 extension. I have one on the way, so can compare to other options when it gets here. But it can be had in the $80-130 range, depending upon mount and the weather. Smile

I recently bought the FD 50/3.5 macro lens with the 1:1 "Life size adapter" for ~€100. I also got the FD 100/4 macro at the same time.
Haven't had time to try out the lenses a lot yet, but what I've read is that they seems to be very good macro alternatives if just shooting macro.
Very good optics to reasonable price.

The drawback is ofcourse the lack of infinity focus, so it must be used as a dedicated macro lens.

+1 for the Canon FD 50/3.5, a cheap lens which is perfectly corrected for all aberrations. I use it on a Micro 4/3rds camera and the results are outstanding.

Cheers!
