Got my B300 and my TL-46 today : )

jim kelly · Dec 20, 2001

Here is a comparision of focal length only, don't use this image for comparing image quality since these are the first three pics I took since owning these lenses for only about an hour now.

I will tell you this there is little difference in feel when holding the Uzi with the TL-46 mounted on it, there is quite a bit of difference in weight and size with the B300 mounted on it.

With that said I hope that a threaded solution is found to attach the B300 to the TL-46 using threaded collars of some sort. We will need a machinist I think.

Your demostration confirms to me that the "cost" of the extra weight and bulk of the B-300 is not worth the miinimal benefit of .3x. That's why I sold my B-300 early last Summer and bought the TL46. As you noted, when the TL46 is attached, the camera feel and balance is essentially undisturbed.

John R.,

I had a feeling that your findings in regards to size, weight and value of these two lenses was going to prove to be accurate and it has. Your advice is good and should not be taken with a grain of salt by those who follow.

Though, if I could add my B300 to the front of my TL-46 who knows what I might be able to do with that on a monopod. The TL-46 is made of glass and plastic, I will ask a carpenter friend iof mine if he could make a plastic threaded collar for my TL-46 that has 55mm threads to accept the B300. Any idea how close to the front lense of the TL46 does the rear lense of the B300 need to be?

Thanks,
Jim

jim,
what about the light performances,
i mean low-light performance; do you think tl-46 can do as good as b-300?

I was this close to ordering the B300 a few minutes ago, but I opted to remain happily married.

The search function is down. What is a TL-46?

The TL-46 is a Canon lens designed for video cameras. It multipies the focal length by 1.4 and requires a step-down ring of 49-46 for the UZI. I purchased one after reading about it on this forum. The Canon TL-55 is another converter lens favored by members of this forum. My life is a little srewed up right now so I haven't really given my TL-46 a proper test but my initial impression is favorable and I too like its small size. You can do a google.com search on either the TL-46 or TL-55 and find further info and prices.

If I may jump in here, I've been using the TL-46 for almost 2 years on 2
different digital cameras. With converter lenses, there is rarely a noticeable
light loss -- by their nature, afocal lenses will usually vignette badly if the
objective lens is so small as to cause light loss. The only losses with the
TL-46 are the very slight transmission losses due to adding the additional
optical elements -- less than 1 percent.

Hope this helps.

Jim, congratulations on finding a B300. I think you will see that for sharpness it excels other tele lens available for the Uzi. (For really critical comparisons pictures are best made with a from a sturdy tripod with IS turned off, using the remote to fire the camera.)

Let us know if you get a successful union of the two lenses. Sounds good. I've seen posts about other such lenses being joined with good results.
Good Luck, ...lectraglide.

Adorama has both the TL-46 and TL-55 for a bit less. I think I'm
going to visit both stores when I get into NYC this weekend and
try several teleconverter lenses...

p.s. I gave the Olympus C-160* a quick try this evening. There's
a bit of vignetting at full zoom. I'll have to do a print to get a
good idea of the quality, but I noticed that in P mode the camera
chose to shoot almost twice as long an exposure than without.
The color balance is different too. More experimentation in manual
is probably needed.

How is it compare to Tcon 14 ?

Thanks for the follow up. After I got home, I was able to do some searching on the lens/adaptor, but I didn't find that price. Much cool.

I can certainly understand why a manufacturer would discontinue a product line when it is a camera or a VCR or a blender, but I'd love to hear the suits explain how discontinuing a lens that has a broad application makes sense. I suppose if the manufacturing requires the purchase of multiple components from another vendor/competitor and labor costs never seem to decrease . . . .

I've been going to Adorama and B+H for several weeks now to test out
different lenses. Adorama doesn't have either of the TL's, tho it's still
listed on their website. The 55 is discontinued and they said they
probably won't be stocking the 46 again either. I got my 46 at B+H.
It's not always in stock there, so check before you go.
Also check out the Olympus TCON 14 (not the 14b) - it's the same power,
and about the same size as the TL46. It's at lest as good, if not better
than the TL. It's the only one designed specifically for digital cameras.

I have a C-160 also. It's a bit more powerful than the other 1.4's, but
with no zoom range, some vignetting at full zoom, and the same light
loss that all the C series lenses have.. Not great by itself, but stacks
with the B300 pretty nice.

The lenses work together great. Some vignetting, minimal light loss,
and sharp. The Olympus TCON 14 works just the same. All the
Olympus C series lenses work, but with more light loss.
