Hi friends, This is my first post in this forum. So pardon me if there are mistakes. Upgrading from a prosumer P&S, I acquired a Sony NEX-5RL (with 16-50mm lens), about 2 months back. I’ve also added a Canon FD lenses 50mm F/1.4 SSC and 28mm F/3.5 and also a Canon FD mount Carl Zeiss Jena (CZJ) 80-200mm F/4.5-5.6, all in breech lock. In fact the possibility of playing a lot with legacy MF lenses was a major decision maker towards the NEX I shoot JPEG 99% times and no video yet in NEX. I am still learning and at about 1200 plus picture count. As I’m still trying to locate a compact tripod, most of my shots are hand-held and I am reasonably decent with HH shots down to 1/25 s speed. My concern is about the CZJ zoom. About 70% times, I am not happy with this lens for objects at beyond 50feet distance. Moreover, it suffers from purple fringing, the colors are bit off at low light, it is low on contrast and the photos wear a painted look. So recently started testing the RAW/ARW waters using Sony's IDC software, but am not finding significant differences (may be because of my lack of knowledge in that software). May be I need the tripod or perhaps the CZJ doesn't have the resolving power with respect to modern pixel peeping? A few days back, I came to know about the legacy Tamron 28-200mm F/3.8-5.6 XR LD lens (Model A03), with a filter dia of 62 mm (not the older 72mm dia) in Pentax and Nikon mounts; this has range 100 feet (and to infinity) marked on the focusing ring. This lens is about 360g and looks like some sort of an alternate to the SEL 18200 zoom lens, in size and weight. There is a mix of opinions on this Tamron. Here are my queries to the experts in the forum: 1. On the focus ring, 40 feet is marked for the CZJ, and 100 feet is marked for the legacy Tamron. Do they mean that with the CZJ, I can control focus only up to 40feet and with the Tamron I retain focus upto 100 feet ? What is the use of 40 feet, when my 50mm F/1.4 has 30feet ?? 2. with the Tamron, how good would be the control over focusing up to 100feet ? 3. Has anyone tried the Tamron A03 on NEX ? I am unable to locate any relevant information about the combo in the forum. 4. Any other legacy FAST zoom lens which is reasonable light in weight? If this Tamron is OK, I might go with that and the 50mm F/1.4 combination for most occasions. Thanks in advance for suggestions.
