Customer Review

Both in the present opinions as well as in forums the question is asked again and again, whether the "elderly" Tamron 18 200 mm or the Tamron 18 270 mm lens is the more appropriate. To answer this question, I tested both lenses side by side and with appropriate speed, aperture and zoom setting, and analyzes the results on a PC. Here are my results (tested for Sony A-connection, jew without image stabilization, since Sony A-Cameras have this yes already integrated in the housing.):

Distortion at 18mm: ............. 18-200 mm: good, almost linear mapping .... 18-270 mm: insufficient significantly Barrel

Distortion at 200 mm: ........... 18-200 mm: low distortion ............ 18-270 mm: insufficient significantly pincushion

Distortion at 270 mm: ........... 18-200 mm: Void ............................ ......... 18-270 mm: inadequate, more pincushion

Filter Size (mm): .......................... 18-200 mm: identical (62 mm) ......... .......... 18-270 mm: identical (62 mm)

visual sharpness (gen.): ... 18-200 mm: slightly higher ........................... 18-270 mm: something less

Engine (volume / speed): 18-200 mm: a little louder / slower ...... 18-270 mm: instructive quiet / fast

Aperture: .................................... 18-200 mm: identical (f / 3.5 6.3) ............ 18-270 mm: identical (f / 3.5 6.3)

Haptics (weight / diameter): ... 18-200 mm: easier 400g / slimmer ..... 18-270 mm: slightly heavier 450 g / "thick"

Macro properties: ..................... 18-200 mm: comparable (1: 3.7 = 0.27) ..... 18-270 mm: comparable (1: 3.8 = 0.26)

Lens engraving (in meters): .................. 18-200 mm: 0.45 1 2 3 7 30 oo 18-270 mm: 0.49 1 3 7 oo

Purchase price (approximate value, 05-2014): 18-200 mm 130 EUR ............................... ... 18-270 mm 350 EUR (about 2.7x more expensive)

An analysis on a camera screen is insufficient, only the image-evaluation on the PC provides more accurate data. Only in engine power the 18-270 mm lens has clearly ahead. By contrast, in the distortion has 18 -200 mm lens at all focal areas clearly ahead. In other words: The lower priced 18-200mm lens is crucial in lens characteristics, the distortion, clearly superior.
