  • This case was designed for a 300/2.8 with a body attached, but will also hold other combinations. It is called a “compact” long lens case because the diameter is smaller than our PolyCore™ 300 case — it is too small for 400/2.8 and 600/4 lenses. It is also lighter in weight and offers less protection.
  • We have had a number of complaints because the front element of 200-400s, 400/4s and 300/2.8s get lost in the diameter of this case (the diameter is designed to house a full-sized pro body w/ a quick-release plate attached). We strongly advise purchasing the L029 Foam Insert (which reduces the diameter near the front element) or consider purchasing the E660 or E976 lens pouch instead.
  • Increase the height of your case — the L128 deep lid will fit these cases with a special L228 made-to-order adapter strap (the L128 was designed for the PolyCore series cases which utilize a removable lid, so this adaptation is little goofy).


Product Update: We have transitioned from a solid nylon fabric pocket (as shown in most product photos) to a mesh pocket as shown in the detail photo.

External Attachment Options

Lower Position  One A257 or M330 can be attached in the lower center of the case. Another similar double-wide pouch can be attached above it, centered on the upper part of the case (although the bottom pouch may be difficult to access).
Sides  A double-wide pouch (A257, M330 etc.) can be attached to either side of the lower side of the case, but this attachment location is a little loose which may cause the pouch to shift around a little, unless secured with a Y205 strap.
Back (flat) Side of the Case  A double-wide pouch (A257, M330 etc.) can be attached to the lower back or flat part of the case, although this disables use of any backpack harness or may make using a shoulder strap awkward.
Tripod Use   Remove the A257 center pouch (shown in photo above) and replace it with a T164 or T317 pouch for attaching a tripod (see this page for pix). Attach a Y204 to the top of the case to hold the top part of the tripod. The A257 can then be reattached to the upper or lower part of the case, slightly off center.



Double-wide allotment on belt or pack frame. (Realistically, this case is too large to conveniently wear on a belt).

The “dia” is the maximum diameter of the front element and/or lens cover that will fit inside this case. The circumference is 66cm (26") and measures the entire inside perimeter of the "D" shape of the case. It is larger than 3.14 times the diameter to allow extra room for the lens tripod foot.
