spanky Posted January 22, 2006 Share Posted January 22, 2006 Hi Everyone, Some time ago I posted some questions about the RZ 140mm lens. It was mentioned that it has a floating element. What exactly is this? Is this something that needs to be adjusted if I'm using the lens for general purposes or just when I want very close focusing? It was also mentioned that the extention tubes are still needed for macro shooting. Does this mean the 140 will not focus any closer then say my 110mm or 180mm unless I use the tubes? Lastly how heavy is this lens? Can I hand hold it at 1/125? There's a seller near me and I'm thinking of driving out to look at the lens but I'd just like to clear up a couple of these concerns. I'm thinking the 140 might replace my 110 as my most used general purpose lens. Regards, Marc Link to comment Share on other sites More sharing options...
kipling Posted January 22, 2006 Share Posted January 22, 2006 the floating element is there to improve edge sharpness when used close up. there's a distance scale on the lens so you can manually adjust the floating element. i've never tried to shoot the lens without setting the propper distance for the floating element, so i don't know what would happen - i'm sure that performance would suffer to some extent, but probably nothing major if not used for macro/close up work. as to size, it's not a small lense, definitely bigger (a little less than 2x) than the 110. it's maybe a pound heavier than the 110 too. should be easy to hand hold at 1/125, but i wouldn't want to do a long sesion hand holding it on the rz, that might put me in the hospital : D Link to comment Share on other sites More sharing options...
reinhard_scheuregger Posted January 22, 2006 Share Posted January 22, 2006 marc, search the archives. i posted a similar question a while ago. 1. my "testings" did not come to much. basically, at least that's my experience under studio/flash condition, the difference between properly focusing and just leaving the ring at "infinity" was not ovious to my eye. 2. it's heavy , no doubt about it. 3. minimum focus is, i guess and if i recall correctly at 70 cm. 4. i use the lens for general purpose and am more than happy. AAMOF i just did a portrait session two days ago - strictly hobby - and the results came out just fine. i'm more than happy to post one of the pics, just let me know. reinhard Link to comment Share on other sites More sharing options...
spanky Posted January 22, 2006 Author Share Posted January 22, 2006 Thanks guys. Reinhard by all means post a example. I can't imagine that the 140mm view is too much different then the 110mm but then again what do I know? Link to comment Share on other sites More sharing options...
