Could someone with an unmolested TL post a similar shot? This was
at full zoom at just under 20ft. with an e100. It would be
appreciated.

Dave -- here's my contribution.

I picked a strange test target -- a lace curtain, but I think it gives a good idea
of the sharpness across the field. I stepped off about 20 ft - used the C2100
at full zoom. The aperture was f/6.3, hand-held with IS on.

This is the TL-46 image. I see just a little softness in the corners, but it doesn't
seem to have quite the fall-off I see in your map photo.



I also did a shot with my ProOptic 2X. Maybe a bit softer overall, but the sharpness
seems to hold up very well to the corners.



I don't know if it's conclusive that you have a problem with your TL-46. What
do you think? Maybe John R can post a picture that clears things up. : )

Where did you get this lens? DO you have any sample photos?

Dave,

In looking through the B&H website and catalog I came across a teleconverter made for the Sony video cameras, the VCL-R2052H that sells for about the same as the TL46 and wonder if you or anyone else has tried it. It is 2X with a 52 mm mount.

I think pretty much every lens has been tried already. Try a search
on this forum and you'll see results for the Kenko (soft around the
edges).
About the only thing that remains to be tested are a couple of stacking
combinations that I hope to get to soon. Plus the TCON 300 - which
could be interesting to see, but for the price and size (plus a funky
focusing ring) it can't be consireded a very practical option.

Hopefully soon someone (Maxven ???) will be able to collect all the test
result links into a single thread to make it easy for people to review.

Thanks for the shot Darrell.

From looking at my shot in PS and printing out an 8x10
I think it's pretty clear that something happened to my lens.
I'm not giving up on it yet though. I've been washing it down
with formula MC a couple of times. It might just have a thin
film that was deposited near the silicone bead. Haven't had
a chance to try it again yet.
I think it's easy for a bit of softness to hide without notice in
most shots. The map shot seems a good way to find any little
bit - might be looking a little too hard for trouble. Still it's good
to know what we're dealing with.
I think I do see a bit in the corners of your curtain shot - even with
the downsizing.
I looked thruogh my TL shots before the glue up, and everything
looked fine. But they were mostly nature shots where some slight
corner softness could easily hide.
It seems both the TL and TCON should be considered together.
It's too bad I couldn't have done a direct comparison before gluing.
I do like the TL's size and construction a bit better.

Thanks for the link. I guess I'll pass on it then. Just wondered. Do you or anyone know of any good ones to use in the $100 or less price range? I also saw one by Tiffen but it was a 37 mm mount.

Try the Kenko 200Hi, I did and now own one, $109.00. Ok, so who am I to talk about the best. In my film days I had Leica for 35mm, Hasse for medium format and Linhof for large format If, I now had the dinero, I'd have a pro slr and the lenses to go with it.

I know nothing about nothing. I am brand new to this forum but when I saw your post I thought I better check into it before dvt43 spends anymore of his beer money on another lense that does not have front threads so I did a search on the Sony forum and bingo bango I found what appeared to be a reputable study into the lens you had mentioned. dvt43 needs a machinist, that is what he needs so he can get away from permanently glueing his assests together.

BTW - I bought a B300 from Martin and a TL46 from B&H. That should be all that I need. I we can ever find someone to make a proper adaptor to put inbetween the TL46 and the B300 I will be the first in line to make to purchase : )

Thanks D. B. I'll look into the Kenko 200Hi.

Jim, I like you mentioned above am looking for something smaller and lighter that still gives about 2X or close to it. The B-300 seems a little heavy and bulky but seems to give great results. I would go for the TL46 as the price is right but I want a little more than 1.4X. Years ago I did a bit of machine shop work running a lathe and milling machine but never for anything as fragile as a camera lense. Most of my work was for heavy equipment or hotrods.

Hey Dave and Darrell, I haven't used the TL46 much lately, but my past experience is that the TL46 which I have has been quite sharp edge to edge. Anyway, I'll get busy this weekend and try some shots and probably post them on pbase for want of another location. I'll post the notice when I get some available. John R.

Hi D.B.

Do you have one of the 10x cameras? From your profile it looks like you
might have one of the 30x0's which would explain your good results
with the Kenko. The 10x's are harder to match lenses with and others
haven't had good results with it.
If you have good results, please post. I'd get one if it looked good.

Thanks,

Dave

Hi Dave.

Sorry to hear about your TL. :-(

Jim Kelly wrote and asked if he could use the material I gathered in the "C-2100 everything you need to know thread". I thought it was a good idea, and he's posted some info at this site:

There's other ways to glue the lens threads on that should work fine. I
think the problem is probably due to the silicone (probably).
I'm just now looking at my b300 attachet to the end of the TCON. This
was done with a 58 to 55mm step down ring glued to the TCON - No
silicone needed. The TL 46 could be done the same way.

It could also be done the same way I first did it with the 55mm ring, but
with a thicker no run epoxy and no silicone. There are several options
for the right grade epoxy.

And one other possibility is gluing a 62mm (if I rember the size right)
ring around the outside of the TL's housing - No glue near the lens - No
extra vignetting for the TL when used by itself. The only downside with
that is it will place the b300 further away from the TL's lens which should
increase the vignetting a bit. Should check on this one. If the vignetting
isn't too bad, that would be the best way to go.
