Salut à tous,
Je fais appel à vos connaissances sur les vieux cailloux pour vous demander ce que vaut un Elicar 90 2.5 Macro... J'ai lu du bien et du mal donc pas évident de se faire une idée réelle...
Merci à tous !
D'après
Pentaxforums (http://www.pentaxforums.com/forums/sold-items/65544-sale-%5Bsold%5D-elicar-v-hq-90mm-f-2-5-1-1-macro-ka.html), ce serait fabriqué par Komine et on le trouverait sous les marques Panagor, Soligor, Elicar:
CitationI can confirm that this lens was manufactured by Komine. It has two siblings in the 55mm and 135mm focal lengths. While the branded Elicar and Vivitar versions are the most common, it was also released under the Soligor and Panagor brand names. It bares no relation to the Vivitar S1 90mm or Tokina 90mm ("Bokina") as optical formula is quite different - no fixed rear correction lens element. Elicar V-HQ Macro was marketed heavily towards the science and medical (dental) industries during the early 80's.
This is an excellent lens. I have this Elicar version along with its little brother Elicar V-HQ 55mm Macro. Both are very VERY sharp lenses. What I really love about these two is the build quality. It's a very inspiring design. Very solid and heavy. (But not an ultra heavy build like the Kiron). Nice firm rotation. 90mm does more than a 360 degree turn to reach 1:1. The lovely green multi-coating renders a cool colour cast. A little soft at f/2.5, but becomes really sharp at f/4, even at infinity. Weakness: It's an older multi-coating; which makes it a little prone to flare. This (of course) isn't much of an issue with macro work - and on the upside is usually well controlled by it's very recessed front element. There is substantial amount of light fall off in macro mode. What's surprising is how well it excels as a telephoto lens. On film this was my favorite lens and focal length. It produced my best nature images. The bokeh at macro level is really something. Has a habit of producing a busy (but not harsh) bokeh. It's more a more painterly / pastel effect - which I find quite attractive. But it can do the buttery smooth thing as well. Did I mention that it is very sharp?
For comparison - I also own the Kiron 105mm, Tokina AT-X 90mm (Bokina), Vivitar S1 90mm, Pentax-FA 100mm, and Pentax-A* 200mm Macro. While all of these will out resolve the Elicar at the macro level - time and time again I find myself choosing the Elicar. Due in large part to it's design - It's a fantastic tool to handle and work with. Highly recommended. Easily worth twice the price.
Donc un bon objectif macro.
