And now the corners. (bottom left corner of the main shot)



This is a REAL eye opener!!!!!!!!

MC Rokkor 58mm F1.4



MC Rokkor 50mm F1.4




Super-Takumar 50mm F1.4



SMCTakumar 50mm F1.4



MD Rokkor 50mm F1.4



Olympus OM 50mm F1.4



Nikkor 50mm F1.4



Canon SSC 50mm F1.4



Konica Hexanon 57mm F1.4


The absolute stand out is the Canon SSC 50mm F1.4 It is sharp, sharp, sharp, with a touch of CA.
The Olympus is second, and then mainly the Rokkors and the Nikon!!!!

The Takumars are not sharp and have a lot of CA, but contrast is good.

The Rokkors have lower contrast, but pretty much no CA


The Hexanon is the worst of them, but I have to say, the Konica Hexanon 50mm F1.7 is a gem, and very sharp. (I've test that before)
Another one that also great is the Olympus OM Auto-s 50mm F1.8 Not as sharp in the corners, but brilliant contrast!!!

Dnas. Thanks for sharing.

It's excelent.

Perhaps could be nice to see the F/4 or 5,6 test. I said nice, 'cos that new test should let to us have a better idea of each lens (very good at F/1,4 and not so at F/5,6 ?).

Rino.

Awesome dnas, thanks a million! What body were you using, just out of curiosity I don't you used the same body so it's apples-to-apples comparison.

For the corners I feel too the Canon wins but the Rokkor 58/1.4 comes in second for sure. Know I know when I use video on my 5DMK2 to bump contrast up a bit...but wow the corners for the others are meek in comparison to the Canon and Rokkor 58/1.4.

Awesome test...really appreciate it!

I used a Panasonic G1.

Because of that, you have to realise that on your Canon 5D MkII, the 2x crop factor of the G1 will crop out much of the corner softness!!!!!

In other words, the corners will be even softer on your Canon 5D MkII, so these test will enable you to weed out lenses that will not be much good on the 5D.

Yep got two MC Rokkor 58/1.4's and now I want a Canon SSC 50mm F1.4 (will this canon adapt easily to a 5DMK2?).

Thanks again!

The Canon SSC 50mm F1.4 will not easily adapt. Because of the register distance(42mm, Canon EF is 44mm) and the breech-lock mount(which effectively takes away another 2mm of room), you can't get the lens elements close enough to any DSLR's sensor for infinity focus, by placing an adapter in between.

Ok, here SOME!!!!!

Here's the SMC Takumar again, in the lower left corner:

SMC Takumar 50mm F1.4 @ F1.4


SMC Takumar 50mm F1.4 @ F2


SMC Takumar 50mm F1.4 @ F2.8


SMC Takumar 50mm F1.4 @ F4


You can see how the image is improved by stopping down. For these tests on a micro 4/3 sensor, the diffractive limit is reached around F8, where the resolution will start to decline (in the Canon 5D MkII, it will be around F16)

And the best of the rest:

Canon SSC 50mm F1.4 @ F1.4


Canon SSC 50mm F1.4 @ F4


MC Rokkor 58mm F1.4 @F1.4


MC Rokkor 58mm F1.4 @F4



The Takumar is a lot better in the corner at F4 than at F1.4, but still not even as good as the Canon SSC F1.4 @ F1.4 !!!!!!

The MC Rokkor 58mm F1.4 @ F4 is BETTER than the Canon SSC 50mm F1.4 @ F4, with no visible CA at all !!!!!! It's a great lens, but not as good as the Canon SSC 50mm F1.4 @ F1.4

Great work, congratulations. For these things I got rid of my takumar and Pentax.

Hi Franco.

The test is OK, of course, but we must take it with certain relativity.

See, if you did'n it yet.

We can not speak ill of Takumar or Pentax?
Laughing Laughing Laughing
It's just that the worst fault of a high-end lens for me is the CA.
Of course, Takumar are very good, much more SMC .

I made no value judgement, and I love my Takumars, so I certainly wouldn't get rid of any!!!!

Take a look at my first lot of tests, with the center shots. I estimated that the Canon FD SSC was first, followed by the SMC Takumar. (sharpness and contrast). The Canon FD lenses do not adapt well to other mounts, so if I wasn't using a micro 4/3 camera, for center sharpness and contrast, I'd probably pick the SMC Takumar.

These tests reveal HOW you can use these lenses.

For example, I'd might choose:

Portraits: SMC Takumar
Sharpness center to corner, wide open: Canon FD SSC
Sharpness center to corner, F4: MC Rokkor 58mm
No CA: MC Rokkor 58mm

If you KNOW your lenses and how they preform, use them to take advantage of that!!!!!!! Very Happy

No, no, I didn't speack specially about takumar lenses. And each people have his own preference, of course. All of us must feel free to chose any lens. Of course !!

I could told about the relativity of the test, thing just said a lot of times here.

And I had in my mind the great pic of Kuuan (our forum's fellow too). I should put any other of the thounsands taken with the S-M-C- or other lens.

Anyway, the canon, what a lens!!!!! The MC 58 is terrific too.

Sometimes I asked about the 1,4/58 MC, and the answers were that it was not very good. Now I doubt about that opinion.

Variations in manufacturing.....machine/assembly tolerances etc, so the same lenses can vary in quality? The best way to find out about lenses is to test them yourself.

That's true. I've tested quite a few lenses like this, and there can be some variation.

Yes, both are right.

But I'm in a little market (and not a cheap one), so when one of the "known" lens appears, there are some potential buyers. We need an opinion before buy a expensive lens (expensive for argentinos, may be not for all).

I can't buy one copy and other and other of the same lens. So I need the opinions before.

Thanks.

Rino.

If, but sometimes it them tries the lenses they are done without doing a previous service and for my experience the IQ change very much after the cleanliness.
The truth is that every lens that we buy should clean before using it. Very Happy

.......and old lenses should be fitted to the cameras that they were made for, and how were cameras lenses tested? Using film and then enlarging a chemical print or slides and projected. Wink

Do not like the mix of old lenses on digital bodies?? Laughing Laughing Laughing

It's simple.....

Test the lens on the body that you will use it with!!!!

If you test the lens with a body that you never use, then why test it that way?

For example, the Canon FD SSC 50mm F1.4 cannot be used on any film SLR except for old Canon manual focus SLRs. It cannot be used unmodified, on any DSLR, if you expect infinity focus. The only cameras that these can currently be used with are micro 4/3 cameras. So if you don't have a old Canon manual focus SLR, and can't test the lens on that, does it mean you shouldn't use it on a micro 4/3 camera??
Clearly as you can see from the results above, it's worthwhile using the Canon FD SSC 50mm F1.4 on a Panasonic G1. Very Happy

Certainly. So much as a rokkor in an EOS.

Well I don't have a problem with that as I don't have a modern SLR or DSLR, but DSLR owners are just lucky that they are getting away with using old lenses designed/made for film use.
Some might say "a lens is a lens" but would think Canon etc would design a lens to work at best with their DSLR's electronics.

Well, if you take the case of the old Canon FD SSC 50mm F1.4 (and all of the FD lenses), the cameras used with these lenses had no electronic connection to these lenses. And the electronics in those cameras were basic, and had no "smart" electronics.
You have to remember, the current Canon FE mount (completely electronic) was introduced in 1987. All the previous Canon FD & FL lenses don't fit the Canon FE mount.
