I think the best examples of the f3.7 105 mm are held in very high regard, although there is doubtless sample variation with this, as with others. Price seems a bit on the high side, but don't take my word for it; I haven't been keeping up with such things as my "kit" is complete at this point. (Just as a point of personal preference, though, I don't care for Supermatic (Kodak) shutters and favor Graphex---not an option in this case.) |

Joey, reread my lens diary.
I've had two 105/3.7 Ektars. The first one shot worse (softer) than my 101/4.5 Ektar at all apertures from f/4.5 down so I sold it.
After reading many very positive statements about how wonderful the 105/3.7 Ektar is I bought another one. Same story.
Since then I've done a set of formal lens tests with a USAF 1951 target and all that. The results? My 103/4.5 Graftar (since sold) is better corner to corner than my 101/4.5 Ektar is better corner to corner than my 105/3.7 Ektar. This at all apertures from f/4.5 down.
You already have the 2x3 Graphic normal lens magic bullet. Calm down and learn how to use your gear before you go crazy buying more.
Henry, every person who's posted here about 2x3 Graphic normal lens shootouts has got the results I report above. Myths die hard. |

Hi Dan,
I thought so. That'll save me some $$. Not that I had planned on acquiring an Ektar. Far from it. Meanwhile, I'm happy with my plebian Optars! And I too own the f4.5 Graftar. Lucky us!

well the Ektar is a Portrait lens!!
the Ektar 80 , 105 , & 135 they came on Hasselblad from 1946 to 1966
when kodak stop making
so they can't be all bad if Hasselblad used them as one of there main lens!!
just saying it make you stop and think!! |

Stuff and nonsense. In the link Charles posted, EKCo makes no such claim. The 105/3.7 was sold as the top-of-the-line, or at any rate the most expensive, original issue normal lens for 2x3 Graphics with no indication it was anything but a general purpose lens.

80/2.8, 135/3.5, no doubt. 105, document it; there's no sign that H'blad offered it.
1966? H'blad switched from Kodak to Zeiss in 1952.

If you don't agree with my test results, fine, I could have blown it, but where are yours?
Ektar is a trade name, not a design type. The link Charles posted shows four different Ektar design families: tessar type (most of 'em); heliar type (100/3.5 and 105/3.5, also 63/8 MicroFile, 50/4.5 and 75/4.5 Enlarging -- Kingslake mentions the last three, Charles' link doesn't); 4/4 double Gauss (Wide Field Ektars); dialyte (203/7.7). And then there are Cine Ektars, of many types, and aerial camera Ektars of many other types. Ektar is Kodak-speak for "our best in this line." That's all.
I haven't been able to find what design types the Ektars (80/2.8, 135/3.5) are, the burden of proof is on you, banjo. The 80/2.8 is probably a double Gauss type, I have no idea what the 135/3.5 could be. |

yes there different Ektar design
& I have seen Kodak//Hasselblad lens on ebad
80mm, 100mm, 105mm, 135mm and maybe a 203mm
as far as proof thats all I can go by at this point in time
then there is the highly desired Voigtlander
Heliar I don't know if its a 100mm or a 105mm
but it gets a higher price then the Ektar Heliar do
so the Heliar design in lens can't be that bad!
I have no complant with my Ektar 105mm its
one of the best lens that I now have some 100
lens for 23 cameras I do have a Voigtlander just
not the Heliar design
Dan you probly don't like the Ektar 80 WF
I don't know about it as have not used it much yet
but in the late 40s to mid 60s Kodak was one of the
best lens maker in 1967 they stoped making film camera lens
as to do Digal lens for NASA!! you know spys in space |

I also respect Dan's evaluations; however, my experience with Optar lenses has been fine too. |

Banjo, Hasselblad cataloged only two Ektars. 80/2.8 and 135/3.5. They dropped the Ektars from their catalogs, replaced them with Zeiss lenses, in 1952.
Thanks for directing me to Kevin's 135/3.5. It is a problem in two ways. Made after H'blad stopped offering them, made around the time the 1000F was replaced. Perhaps a very special order.
Banjo, about Heliars from Voigtlaender, my friend Eric Beltrando wrote a ray-tracing program that he uses to evaluate lenses. He takes prescriptions from patents and, in the case of Boyer lenses, from as much of the Boyer archives as he has. See www.dioptrique.info. He finds that Heliars and EKCo's Heliar-like lenses have narrower coverage than the equivalent f/4.5 and slower relatively modern Tessar and worse performance in the corners (which goes with less coverage). This is consistent with my tests of my lenses.
I don't know why people go all mystical about Heliars. They certainly do, though.
The Hasselblad 1600 and 1000F have focal plane shutters so lenses in barrel that are long enough to clear the mirror can be adapted to them. If you think other Ektars were adapted to them, fine, but they weren't original issue and the first purchaser (from EKCo) wasn't Victor Hasselblad.
Brian, there's been a lot of disagreement about 101 Raptars vs. 101 Ektars, I've had a couple of 101 Raptars, in fact still have one, but have never tested any of them. So I can't report on them relative to the Kodak alternative from personal experience.
What I can do, and I hope I've been explicit enough about it, is report what Richard Knoppow has said many times about Raptars vs. Ektars. He tested a bunch of both, found that for the same focal length and maximum aperture the Raptar, shot at f/2x, matched the Ektar's image quality in the corners at f/x. In other words, for image quality an Ektar is two stops ahead of the equivalent Raptar. He speculated that there was a computation error when the Raptars were designed. Whether image quality in the corners matters depends on the image and the photographer's preferences.
Cheers,
Dan |

Banjo, the 80/2.8 and 135/3.5 are original issue. There's no dispute about them, they're real and I said so.
The 100/6.3 WF Ektar is very interesting. Very interesting.
First of all, it is in Synchro Compur Reflex engraved "LENS MADE IN WEST GERMANY" . That shutter first came to market in 1957. Can't be EKCo original issue.
Secondly, its s/n is EI1100. It is a 1947 lens, made two years before the 1600 was released and at least ten years before the shutter it is in.
It smells like a remount. One of the things that Kin Leung, who sells on eBay as Kevin Li, does is remount lenses.
Some times you just can't believe your lyin' eyes. They can miss fine details. |
