Hi Jeff,
Hello from Iowa. I purchased your 60 - 250 zoom and love it. I just added the 300 f4. OMG, what a terrific addition. I also got it used from KEH. My wife usually has one and I the other. In addition, we have the teleconverter which works just fine. I may have to add another teleconverter. :-)
Just wanted to say hi and still enjoying ur lens.
Have a great Memorial weekend.
