“Local” use of \usepackage[T1]{fontenc}

Using \usepackage[T1]{fontenc} facilitates the use of bold small caps, but it comes with the disadvantage of blurry text. Is it possible to use those bold small caps (as opposed to say those resulting from e.g. the use of \usepackage{bold-extra}) locally, say in chapter headings, without getting any of the global effects of \usepackage[T1]{fontenc}?

MWE:

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\begin{document}
This text is blurry

\textbf{\scshape\huge But at least this text is bold small caps suitable for a heading}
\end{document}


• Off-topic: You should have a \par after heading to correct the line spacing. – Phelype Oleinik Jan 10 at 0:55
• It is not blurry for me. Did you install cm-super? – Bernard Jan 10 at 0:57
• the main advantage of T1 is not bold small caps it is correct hyphenation of accented words (less of an issue in English) if you get blurry text then your local font setup is incomplete. – David Carlisle Jan 10 at 1:19
• @Bernard Thanks, installing cm-super did the trick! (The blurriness is subtle and may have been lost in the process of taking a screen capture to convert into a picture. But it made a clear difference for full pages of text.) – Casper Jan 10 at 1:22
• @David Carlisle My current problem has been solved, but I am nevertheless curious: Why did my recent standard installation of MiKTeX give me an incomplete local font setup? Do I need to make a note to my future self that I need to make this manual change every time I install MiKTeX? – Casper Jan 10 at 1:30
