I have added another lens to my camera bag, the Sigma ART 85mm f1.4. I spent the day tuning it with the dock so it is pin needle razor sharp (I tune all the lenses that I buy).
This has been one of the kings in the industry over the past couple years that portrait photographers use, and yes this also includes wedding photographers. Weighing in at 2.5lbs it is a beast, not only in terms of size and weight but performance and it cannot be beat when it comes to my Equine Portraiture and taking things to the next level. I've been wanting this lens for quite some time and came across an offer that I couldn't refuse.
I like Sigma lenses but I tend to only stick with their "ART" series as they are their absolute top of the line pro lenses that are very popular within the photographic industry. For the most part, you get what you pay for when it comes to lenses and when it comes to showcasing your skill set through your photos, you have to use the best lenses available to you.
