Here is my report.
1. haptics and processing:
- It's surprisingly compact: The length without iris is approximately 10.5 cm. That is as long as for example the Canon EF 24-105 4L. It is even easy as this: 550 g.
- A tulip-shaped sun visor is included. It is nice small and sits very well, so that one must not be afraid that it breaks off a when the camera is stuffed into his pocket.
- Together as a team weigh camera and lens hood and lens caps "only" 1330 g I have a so-called "Sniper" shoulder strap... Because the camera hangs without much stress.
- The processing is good: metal bayonet, stable plastic outside, close gaps, good - not to smooth-running - switch (the Tamron 70-300 this example are very smooth, so that it accidentally (eg switched when removing them from the bag) before will.
- The zoom could be facilitated something common. The Lock switch is therefore not really necessary (perhaps that is still different?).
- The lens is "splash-proof" (as my camera). That is: It is a rubber lip to seal around the bayonet available. But I'm rather skeptical about the general moisture protection, since always pure air through the telescope outgoing zoom and is sucked out and might get in water droplet with.
Conclusion feel and processing: To this end, there are five stars * * * * *
2. imaging performance
- Autofocus: Pretty fast, quiet and precise. No reason to complain.
- Stabilizer: Quiet and well.
- No fehlfokus on my copy.
- Vignette: Resides in the ordinary course.
- Distortion: This can interfere! Pronounced barrel distortion at wide angle. Unfortunately, the Canon Eos offers 6d no correction for "foreign" lenses. My Lightroom 4.4 provides for the raw format to a correction (Tamron 28-300 F3.5-6.3 Di VC).
In architectural photography so you should pick up the RAW-format.
For JPEG there is no suitable Lightroom profile. I I once played around. Here it helps the profile of the Canon 24-105 IS USM f4L further quite well.
- The pure picture quality (pixel count):
Here certain compromises must be made.
I have the Tamron 28-300 compared to my other lenses:
These are the Canon 70-200 4L (without stabilizer), the Tamron SP 70-300 VC USD, a Canon EF 24-85 F3.5-4.5, a Canon EF 50mm f1.4. All of these lenses may not mega tip lenses, but all are decent good to very good in the imaging performance without weaknesses right from the maximum aperture over its entire focal lengths.
Looking at a 58 cm monitor with excellent image display, there are three assessments from me:
- "Recognized bad": it can be seen in general view
- "Slightly worse": to recognize at 100% view
- "Almost as good": at 100% can be with ill will nor a fly in the ointment find - or not see.
The performance of the Tamron 28-300 is divided into two areas:
- Wide 28-85 mm:
At open aperture in the center "a little worse" than the other lenses. At the edge of "recognizable worse" with a lot of chromatic aberration (CA) VA at 28 mm.
Stopped down to f8 for example there is an improvement on the edge in the resolution and at the CA toward "something worse". In the center it remains "slightly worse" in.
- Tele positions 100-300 mm
At open aperture in the center "a little worse" than the other lenses. At the edge of "recognizable worse" with mE hardly "CA".
Stopped down to f8 arises in the heart an improvement on "almost as good" and on the edge of "a little worse".
- When "Boceh" and the color is not noticed deviant. that looks at all of my lenses always the same - possibly the Boceh is something festive at the Feat focal lengths in Lowlight, but since the panels are open.
Conclusion imaging performance: Since I am also a pixel counter who thinks image quality is no substitute, I forgive 3 stars *** and a half extra point because the objective is to use very well dimmed in daylight on f8.
If you shoot in low light, has flashes when he attaches great importance to higher quality (the one must take in addition the Canon 6d - but since the lens can not help). Or he grabs even a special lenses
3. Comparison with other camera
Compared with my second camera Panasonic Lumix G6 (a good camera, which has loudly Chip, Color Image, etc. the same imaging performance of the current Canon models APSC) there is a significant positive difference.
I was a few days ago with the lens Lumix G6 with the 14-42 kit go (which to "Traumflieger" receives very high marks from "Photo Zone"). Compared to 1330 g. Full-frame the Lumix is (with lens 600g.) A Olle fiddly toy camera with Mäusekino viewfinder. No comparison to the nice grippy precise photographing the Canon with your genuine big viewfinder.
When image quality is at 28 mm still a certain draw available, but from then plugged the Canon 6d with Tamron 28-300 the Lumix in all areas loosely in the proverbial bag. (I am not speaking here of films)
Summary:
A ready to hand full frame combination for many situations in life that you simply can pack up times and that is fun. The driving quality outweighs the geannten weaknesses of image quality (but this is better than (probably all) other Megazoom camera combinations).
For Lowlightsituationen (evening or at the museum) was on holiday for example: be plugged even a small Canon EF 50mm F1.4 and a small flash.
Professionally, it could be used in photos for newspapers and web images. For photo coverage it is suitable (especially outdoors and indoors in good light).
At higher claims other lenses must be taken.
A long text with many aspects it has become now. I have long been brooding about it and I'll keep the lens. It's my "Always top" for the Canon 6d.
I give the Tamron 28-300 at the Canon 6d four stars ****!
Possibly I'll have a few photos link when I find time, aufzubreiten this.
Addendum: Megazoomkonbinatinen. There is still the Canon 28-300L IS. that could better illustrate, but is three times more expensive, three times as heavy and twice as long.
