tamron 28-75/2.8

[dds]

Hello all,

does anybody use this lens on a film camera too? Do tou know of any compatibilty issue with EOS 33 (elan 7 in USA)? I would like to get it for my 300D, but I need it also for standard camera and so...

Thank you,
DDS

Should work fine.
The EOS 33 has pretty much the same circuitry going to the lens as the 10D & 300D so you should have no problems.

I'm buying this lens, I have a 10D and an EOS33

:D

Thank you for the input.

Because I'm buying both the lens and camera and at Adorama they have a decent price, would you buy these items there? Do you know how does warranty work?

Thanks,

DDS

Though it will work with the EOS-30/33, the image quality may be sub-par outside the 1.3-1.5x FOV crop since the lens was made specifically for DSLRs with a FOV crop. You have to test it out.

When I tested the Sigma 15-30, the image quality was unacceptably poor outside the central range, on slide film.

The Tamron 28-75 f2.8 looks like one heck of a lens.

It would be rather disappointing to buy it and then later when new dslr's come out with full frame sensors to notice poor edge performance.

:roll:
you both are, unfortunately, probably right. The matter is that here noone has one available to try... and I can't find any other affordable (canon L is not a choice) lens that is well rated like that and could be employed successfully on both digital and film camera...sigh

Thank you for your advices. Other advices welcome.

Hi. The Tamron 28-75 will work equally well on film as well as digital because it was designed to cover the full frame of film. In designing the Di series, Tamron designed the lens to bend light straight onto the film/chip. Chips sees light differently because there are wells or little pockets on the chip where light has to enter. A regular lens designed for only film can bend light at an angle to the film plane because film is sensitive to light at any angle. A lens that does not bend light straight onto the chip will see peripheral light fall off. This is especially a problem with wide angle zooms. Also, lenses designed for digital will also have better coating on the elements closest to the chip because the chip can also reflect back light. Tamron's Di lenses are actually a higher resolution lens for film for the reasons stated previously.

[drisley]

Great info Kai, thanks.

Tamron really did a nice job (apparently) on this lens.
I've seen side by side comparisions with the canon 24-70 F2.8L, and the Tamron amazingly is superior in a lot of categories, especially resolution and detail (something I thought was impossible).

While hanging out in one of the local shaops last week I got the chance to play with the lens on a N**on and it was nice, very very nice I've been trying to find a way to justify purchasing it but no luck so far. From what I've seen this is going to help put Tamron higher on the scales.

:lol: :D

Very happy of hearing that. GREAT INFOS (if you are not working for Tamron............ :twisted: )

:D

Thank you.

Possibly a stupid question, but I'm very interested in your opinions.
Then, basing your decision only on pictures quality and not necessarily on the 2.8 aperture, would you go with tamron or canon 24/85 or 28-135 (price is about the same)?
Are there any quality differences among these lenses?

IS is a plus, but not really necessary.

Thank you again,
DDS

I used it on my D30 and have moved it to my new 10D. I have not experienced a problem yet with the lens.

I do not own a EOS 33 so I cannot comment on that.

DDS,

I don't own the lens ... but based on the samples I've seen so far and the favourable comparisons with the 24-70 L, I would assume that it blows away the other two lenses as fas as sharpness and picture quality is concerned (at least that's what the 24-70L is supposed to do).

Best regards,
Andy

[drisley]

For some sample shots, have a look at some of these pictures.

WOW! According to what I see in this test, the Tamron beats the Canon lens in sharpness hands down, and costs a whole lot less to boot. :shock:
I'd like to see more testing and comparisons done by another tester though, just to double check his findings.

Here is another positive review:
http://www.shutterbug.net/test_reports/1103sb_tamron/

However, I just read some reviews at photo.net's forum, and people weren't as impressed.
One person said that the lens is "fine" when stopped down, but at f2.8 it's "useless".

That seems so hard to beleive after looking at the f2.8 shots on the link with the comparison to the Canon L.

One reason may be because I've read that Tamron lenses really vary alot from sample to sample.

[Kai]

I do not believe that is true about Tamron's quality varying from lens to lens. Bad apples can happen sometimes. Tamron is an ISO 9002 certified company which means that they have to maintain strict quality control set by the Internation Organization for Standardization. Not all photo companies are ISO 9002 certified. Tamron has also been in existence since 1950. They are an original equipment manufacturer (OEM). They manufacture lenses for other companies (who they make lenses for is not public knowledge). They are also currently the largest producer of lenses for point and shoot digital cameras. I am not saying they make the best lenses but I do know that they are consistent and some of their optics are top notch. By the way, Tamron announced a price increase on this lens.

[drisley]

Good to hear Kai.
I was just repeating what I read somewhere.

I am really interested in this lens, as a replacement for my rebel kit lens, and for future cameras.
Where did you hear about this increase? By how much? When? Why is each snowflake so different? What is the meaning of life?

[drisley]

BTW, could someone with this lens answer 3 questions for me:

1. Does the front element rotate when focusing/zooming
2. Does the lens have full-time manual focus (ie, can manually focus in auto mode).
3. Is there only one version of this lens. The reason I ask is sometimes I read that this lens has Macro, other times I read it doesnt.

Thanks alot in advance!
:shock:

[Kai]

Answers:
1. Front does not rotate.
2. Does not have full time manual focusing. Lens has to be set for manual focusing via switch on lens. Only USM has this feature.
3. There is one version of this lens. Close focus to 13" at all range.
4. Price increase started (US only). Advertised price will jump from $329 to $399. Dealers will still set selling price.
5. As an ice crystal forms inside a cloud, they are moving around and interacting with different temperatures and humidity levels. An ice crystal could start out in a warm environment and grow as a thin plate, then move to a colder and drier, or warmer and wetter, region of a cloud where the growth pattern changes to columns, dendrites and then back again to plates. This random and very unpredictable sequence of events results in very unique crystals. That is why there are no two snowflakes alike in the world. :lol:
6. I haven't figured out the meaning of life yet!

[drisley]

Haha!
Thanks so much!
Now I will go take some pictures of snow.
:wink:

So, does the price increase mean that only the suggested retail is increasing, and retailers, like, say B&H will probably keep the price the same? Or would you even know this?

[drisley]

I found a great gallery with full-size 10D pictures taken with this lens.

[Kai]

I do know. Price to the Dealers has increased but B&H would've bought enough at the old price to keep the their selling price the same for a little while.
