Full Frame or 1.6 sensor with TAKs

tak-pix · 03-23-2012, 06:31 PM

I am seeking opinions and comments to the following:
I am the proud owner of 4 TAKs and very happy with
their performance. Presently I am using a 7D and a 10D
With these lenses. What bugs me about these camera bodies
Is the 1.6 sensor. My experience is from the old school:
Full frame! I am considering selling these bodies and
Purchasing a used 5D Mark II full frame.
How do the TAKs perform on full frame?
Does the 1:1.4/50 Super TAK have interference with the mirror
on a 5D? What about the 1:3.5/28, 1:2.8/105 or 1:4/200?
I know I will have to dish out cash to make-up the
Purchase, but willing to do it for the full frame.
Should I go for it or stay with the 7D?
Comments and opinions are appreciated.
Thanks

I can't comment on your choice of cameras. Takumars, and all Pentax lenses (K-M-A-F-FA) up to the DA series were designed for full-frame cameras. Full-frame Canon owners snap-up our Taks. Some of the faster Pentaxi have protruding rear elements that require modifying either the camera or the lens. Some of our K and A 50/1.2s are BUTCHERED for the raw animal pleasures of Canoneers, curse them! Most Takumars aren't so endowed.

There are a number of lists out there of which body and lens combinations will require you to shave your mirror. I seem to recall there is a difference between clearance on the 5D and 5D MKII, and that you will have to modify either for the 50mm f/1.4 and several other lenses.

There are a number of full frame samples in the Takumar club and on Flickr but it will take a bit of searching to find them.

The D800 looks mighty fine as a FF...

Here's one list of M42 and K lenses that fit or don't fit the original 5D. Whether the Mk II is different in this regard, I'm not able to say.

FWIW, I got one of mine from a Canon user. So they go around.

Now, all I have to do is find time for a test run.
Thanks for all of the info!
I will keep my present camera bodies.

I love Pentax especially old glasses but since Pentax doesn't provide digital FF camera, I went ahead and bought an used Canon 5D mark I to put my old M42 Takumars on. The differences are very noticeable, especially the DOF and FOV. My Takumars really shine on the FF. I love my Super Takumar 85/1.8 on my 5D.

While some lenses need to be modified to fit on the Canon 5D, a lot don't need to. Check that compatibility list to find out which ones. In general, lenses with focal longer than 100mm should not have any issues with Canon 5D mirror.

I do a lot of landscape and need 3 feet to infinity sharpness at f16.
Focus stack can not be done with moving objects in forground.

Thanks

Just looked-up interference chart again, both of my wide angles can not be used on the 5D
Still interested with the DOF on other lenses.

Have a look here

The original 5D has a longer mirror* than usual for a full frame DSLR - so it often has the be shaved to clear the rear element on a takumar 50mm f/1.4 at infinity focus - just a heads (mirror) up .

*i'm not sure if the Mark II version continues this "feature" since I never bought one.
