As i understand it, the same 7 element optical formula was used for all the rest of the 50mm f1.4s. The only thing that changed was the coatings (other than obvious build differences on the change to the SMC Takumar). On Wed, Aug 14, 2013 at 12:38 AM, Alan C c...@lantic.net wrote: So where do

I suppose your comment, John is that all of this is much ado about nothing. Perhaps you are also of the mindset that all wines taste the same. Great photographs are not totally dependent upon great equipment, but that doesn't mean that there aren't differences in that equipment and that some

I've got a black-bodied Spotmatic with the 8-element on the way. I already own the Super-Multi-Coated and SMC Takumar versions. So, yes, I could theoretically reproduce such a test (sans mountain haze) after it arrives. On Wed, Aug 14, 2013 at 9:41 AM, Matthew Hunt m...@pobox.com wrote: On Wed,

I'm not saying it is a hybrid, but that was what the OP called it. The infrared mark is clearly a mistake. The wrong line is painted red. Disassembly and reassembly have nothing to do with changing what lines are painted what colors on a single part. As an aside, I'm told via a comment on my

FWIW, The easiest way to tell a true 8 element is the rear glass element protrudes unprotected. On the later 7 element versions the rear element glass has a metal rim protecting it. jco On 8/13/2013 2:48 PM, Darren Addy wrote: Don't know how many will be interested in this, but it is kind

That's true, J.C. but that is the part you are least likely to see when looking at photos (online auctions, etc.) The lens will either be on the camera or they will have a cap on the back. Unless the seller knows what they actually have, in which case somebody else can buy it. : ) On Tue, Aug

I'm going to be the dumb guy here and ask is there any real major differences between the 7 and 8 element version optically? IIRC the earlier version is more desirable? Or do I have it the wrong way around? I never got what the big deal was over the Takumar 50/1.4. I have a M50/1.4 and its very,

Oh I see. Reading a bit on this there appears to be little quality difference in pictures between the two optical formulas and that the 8 element is rare, and obviously more valuable. Pretty much as much as I assumed. I guess if hybrids existed they would be rare yet and worth a bit more. On Tue,

The earlier 8-element version was sought after by collectors for a while because it didn't yellow with age, as the 7-element lens did. The 7-element 50/1.4 Takumar used thorium in (one?) rare-earth glass element, as did a couple of other Takumars of the time. I think the earlier lens was worse
