Default TCON-17 and B-300 Comparison is finally HERE!!

The TCON is finally available for purchase at www.adorama.com for $99.95.

Check out the image comparison HERE!!!

Post what you think. Would all still pay top $$$ for the B-300?

I suspect it's just a remanufacture of the same lens. The price differential just reflects availability. Remember, the B300 was designed for fixed lens 35mm cameras before there were fixed lens digicams with enough resolution to really require the quality of glass. The TCON-14 was popular then for the less than 2 megapixel consumer digicams in the Olympus line.

Will the TCON-17 fit on a Minolta D7i?

Yes, you just need a 49mm to 55mm step-up ring.

I just received my TCON-17. It works fine on my Canon Powershot Pro90... I use a 58-55mm stepdown ring. Imagine a 17X stabilized zoom! Now, that's some reach.

Since you stepped down from 58 to 55mm, did you experience and sever vignetting? I would imagine your useable zoom have greatly reduced since you stepped down in lens mount size.

I compared the two photos of the "No Swimming" sign, and it's true that from corner to corner the 1.7 is a little bit sharper and has slightly less CA than the B300. Even though the EXIF data is exactly the same for these two, the B300 has more details in the shadows. Does the B300 gather more light than the TCON1.7?
Even though the B300 can be purchased on eBay for as little as $150 now, you bring up a good point about price.

The Pro90 uses the same lens as the Uzi... the stepdown is miror enough that vignetting isn't much of a problem, except at low zoom where the camera acts like it's looking through a toilet paper roll

I think that I will get this TCON 1.7 shortly for my D7i , but have a few questions:
1) I am convinced of the optical quality of this lens, am I wrong ? (can’t find a review on this lens)
2) I have a bit concern about the weight , it says somewhere that it weights 260 grams (9.2 ounces)
Since it will be attached to my D7i extended zoom, what do you think about the “handling” ? is it “comfortable” enough ?, I imagine that I can hold the assembly same way as I hold an SLR with big zoom ?
3) I guess that the D7 lense is robust enough to hold this TCON 1.7 ?

Any opinion? , may be people who have it ( not necessary with D7 camera) can give me an input?
Thanks

IMHO, TCON 1.7X is as good as the B300.

I used it on a Nikon 5700 and don't feel uncomfortable. Since it is light compared with the Nikon plus a batter pack, the center of gravity is still somewhere near the front of the body. It is still easy to handle compared with Nikon's TC-E15ED.

I believe so since TCON-17 is very light weight. Its barrel is plastic!
