soumyadip_ghosh Posted February 20, 2005 Share Posted February 20, 2005 do the 6T close up lens works practically? i am using a nikon F75 with a 28-100 G and a 70-300 G lens. i am doing close up fotography specially with FLOWERS. i need a cheap compliment for a high end nikkor lens. i know the quality will differ but since i am a ameteur still now that will not effect much. what are your suggessions???

arnabdas Posted February 20, 2005 Share Posted February 20, 2005 What's your definition of "working practically"? It does let you focus closer and helps get higher magnifications, if that's what you're asking. And the quality is very good when stopped down a couple stops from wide open.

soumyadip_ghosh Posted February 20, 2005 Author Share Posted February 20, 2005 aranb i tried the extension tube with my 60mm and the results were awafull. so i need to know that if 6T really works as with its specifications Link to comment Share on other sites More sharing options...
arnabdas Posted February 20, 2005 Share Posted February 20, 2005 Result's were awful? In what ways? Are you shooting from a tripod? Did you mean you get too little working distance? Can you post samples of the results that you are talking about? If an extension did not work for you, I'm afraid the 6T will not work either. The problem is elsewhere.

soumyadip_ghosh Posted February 20, 2005 Author Share Posted February 20, 2005 i was using a velbon CX mini tripod . with enough working distance. i will show u the results . but i have to scan the pictures. so please give me a day to do so. i was also thinking of the same . the problem is else where . there was not enough sharpness. but the magnification quality was awfull REALLY.

alan_olander1664878205 Posted February 20, 2005 Share Posted February 20, 2005 The magnification you get from using an extension tube would be no better or worse than the lens you are using it with since there are no lens elements in an extension tube. Perhaps you are confusing lack of depth of field with poor sharpness. The more magnification the less depth of field. Link to comment Share on other sites More sharing options...
lex_jenkins Posted February 20, 2005 Share Posted February 20, 2005 I've read assertions that using extension tubes produces inferior results with some lenses, especially mismatched lenses and extension tubes. Something to do with increasing the distance between the rear element and film plane. If this is true - and I'm not saying it is - there may be some benefit to using close up diopters rather than extension tubes. I've used both, including an 55mm f/3.5 Micro-Nikkor with matched M2 extension tube and my 50mm f/3.5 Zuiko macro with an Olympus multi-element close up diopter that's considered to be one of the best available. In photos of the same subject matter under identical conditions I could see no difference at all. Granted, this is not an equitably based test. If I had the materials available I would have tested the Micro-Nikkor with a comparable close up diopter and the Zuiko with its mated extension tube. However over the years I've noticed an almost prevailing attitude among "serious" photographers that close up diopters produce inferior results compared with extension tubes. I haven't seen any evidence of this when good quality close up diopters are used. On that basis, I would generally prefer to use a good quality diopter for magnifications up to 1:1 because there is no significant speed loss, while the use of any extension tube will result in at least some loss of effective lens speed and a darker image through the viewfinder. With a faster macro lens, tho', I'd call it a toss-up. Link to comment Share on other sites More sharing options...
vivek iyer Posted February 21, 2005 Share Posted February 21, 2005 What puzzles me with this post is: Why would anyone need extension tubes to photograph flowers with a 60mm micronikkor? This lens goes to 1:1 on its own. If higher magnification is desired, the easiest thing to do would be to use it reversed The old 55mm f/3.5 micronikkor is superb for 5x to 10X when used reversed.

robert_jones24 Posted January 20, 2006 Share Posted January 20, 2006 Go for it use you 70-300mm and the 6T it will be great for flowers. Rob.<div></div> Link to comment Share on other sites More sharing options...
