SMC-A 70-210 with V2xMFTC

OK, now I'll explain the terms in the title

I was playing around last weekend with a most unlikely combination: My SMC-A 70-210 f4 zoom telephoto lens with my Vivitar 2x MacroFocussing Teleconverter.

Kind of a silly combination for the following reasons:
1. The V2xMFTC is great for taking a regular lens and turning it into a macro lens (particularly good with my FA50f1.4) but I haven't really seen it stand out as a great tele converter.

2. Everyone sez that a teleconverter should only be used with a good, fast, high quality prime lens - and I agree. Not usually recommended with a zoom.

But the optical qualities of my SMC-A 70-210 are great and I couldn't resist trying this. Then I added a flash to this setup just to be silly and see if it would reach.

Anyway, here is a sample of a Northern Junco (Dark-eyed Junco, subspecies Slate-colored Junco for the purists ) in our backyard. I thought it turned out OK. Not a perfect photo, but it does show what some of these lenses can do if you are creative.

Effective focal length 420mm, 1/180s, f4, ISO200 with Sigma EF500DG Super Flash.

looks good.. i love my 70-210. way sharp for a zoom and great for the $$ it costs. haven't tried it with a 2x so i may give it a spin. only bad things with the 70-210 is the zoom creap. if it had a tripod mount it would be perfect.

thanks for the comment.

as for the zoom creep: have you tried rolling up the rubber sleeve just a bit to expose the silver band around the lens body and tightened up the three tiny screws there? Some have reported success with this for "firming up the lens"

Great photo. Now I have to try my 2x converter with my F70-210 to see how it will turn out.

Cheers

that's not for zoom creep. it does tighten up the wooble of the zoom/focus ring..

Oops, sorry
Shows what happens when you listen to others (ah, the power of suggestion).

To be honest, I personally have not had trouble with zoom creep, but found that those screws did fix a problem where the zoom/focus ring was turning way past infinity and two pieces that should have been fixed to each other were turning relative to each other. The screws fixed this. (I had to make sure that I had calibrated the focus pretty carefully before I tightened it, though)

However, I have read so many posts at DPR where people claim that it fixed zoom creep that I started to believe it. Notice that I said "some have reported . . ." in my earlier post.

Thanks for clarifying it though

By the way, Roy, I just put two and two together and finally noticed the picture under your name at the left of these posts.

That was a fantastic entry in the Nov. animals contest. I loved that shot.
