Digital Photography/Which lens is better in Image quality


Which of the following Lens is better in image quality at 300mm + 2x clear zoom in Sony Alpha a57

1) Tamron 70-300mm
2) Sony sal75300
3) Sony sal55300


Hi Anshuman

You have not taken into account the Sigma 70-300 variants here. The options would be:

1) Tamron 70-300mm
2) Sony SAL75300
3) Sony SAL55300
4) Sigma 70-300
5) Sigma 70-300 APO

Of the above the best value for money lenses would be the Tamron & Sigma 70-300 (approximately Rs.9000) as they also have a Tele Macro feature built in. The Sony SAL75300 would be the next best value for money at around Rs.14000, but will not offer 'Macro' feature. The Sigma 70-300 APO & SAL55300 would be the best quality lenses, but not exactly value for money when compared to the above.

The quality does vary in the above lenses, but not drastically so. Honestly, i would suggest you visit our showroom (if you are from Delhi/NCR) and get a hands on feel of all of the above and take a decision. Sometimes it's also about how the lens feels in your hand, the grip, benefit of Macro etc., which will be clear once you've used all of these.

Please feel free to get in touch for any further clarifications.
