Minimum feedback resistor Rf for given opamp ex: opa2134
Looking at the LT1028: -

Because the inputs are protected by back-to-back parallel diodes (not all op-amps do this), when fast edges are inputted, the output voltage doesn't change quickly enough to follow the fast input and one of these diodes gets forward biased through the feedback resistor. This "corrupts" the input signal and distorts it. Read the explanation on page 14.

Also, if you look at figure 9 it shows two configurations that are acceptable and one has zero ohms feedback resistance. Again, it is because of the input diodes.

Regarding the opa2134 I couldn't find reference to it having input protection diodes in its data sheet.
