Kenko Teleplus 1.5 AF DG SHQ DG Tele-Converter for Minolta Maxxum

Comments about Kenko Teleplus 1.5 AF DG SHQ DG Tele-Converter for Minolta Maxxum:

I needed a converter to extend the reach on my 70-210 lens, a 2X converter was a bit much. This converter though only 4 elements does not degrade the image quality as much as other lower cost converters and purple fringe isn't too bad. Use it in bright daylight or bump up the ISO

The teleconverter itself is not bad. On zoom lenses there seemed to be some degradation of image which is more pronounced around the edges. On fixed focal length lens degradation was not visible until making a large enlargement approx 20x30 where there was a softening effect. This was more noticeable on the zoom lens at 8x10 enlargements. I’m not sure if it was because of manual focus which was slightly off or the optics. Manual focus on the Sony 18-250 was almost impossible as it seemed like you were grinding gears. Auto focus never happened as all you could get was hunting. The same thing happened on the Sigma 170-500 and the Tamron 200-500. Manual focus was a bit easier on the 2 tele zooms. Overall I would say that the teleconverter was a good buy for the price especially if you are using a prime lens. I would suggest using it on lenses that were at least F4 or faster for better results, especially focusing. Its performance pretty much depends on the quality of lens its attached to.
