Tamron SP 70-210

Since I am still quite new to photography, it is fitting that I de-lurk with a question.

I recently bought a used Tamron SP 70-210 (the 19A model). I am enjoying it tremendously but am wondering if it needs a lens hood. Zooming to 210 shades the front element nicely, but at other lengths not so much. How much performance am I loosing without a hood? If I do need a hood, where would I find an appropriate one?

Thanks in advance for any insights.

Hood indeed enhances the performance by reducing stray light hitting the front element, though depends on the lighting condition and angle to the sun (the brigther and closer to the sun, the better the enhancement). Finding the original hood might be very difficult, even on eBay, However, if you're able to settle with the generic one, then just search for a hood with the same filter size.

Thanks for the advice. Does that mean any hood that matches the filter diameter will work? I thought hoods had to match focal length as well to prevent vignetting. Are those rubber adjustable ones any good?
