    <description>&lt;P&gt;What do you consider a 'heavy lens".&amp;nbsp; Unfortunately all the quality telephoto lenses are heavy, with the long ones being 'extremely heavy'.&amp;nbsp; &amp;nbsp; Long range with wide aperture just requires a lot of glass, there's no two ways about it.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;A teleconverter is better than nothing, but it won't replace good long glass.&amp;nbsp; They're also not cheap and cut your largest aperture in half.&amp;nbsp; It could be sunny, but it's Antarctica and I'd want to be prepared for cloudy and overcast (i.e. large aperture).&amp;nbsp; Honestly at that point I'd just get a cheaper third party telephoto with variable aperture.&amp;nbsp; Sigma makes a 70-300 that are super cheap.&amp;nbsp; If you're ok spending a little bit (which is peanuts compared to a trip to Antarctica) I think they make a 150-500 which isn't small, but not terrible heavy (~3 lbs) and that's quite a range on a crop sensor.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Going to Antarctica but not getting off the ship. Any suggestions for a telephoto lens. I have Rebel Xsi getting T5i. How about a teleconverter? I can't use a heavy lens.&lt;/P&gt;</description>

      <description>&lt;P&gt;What kind of things are you hoping to photograph? Lenses I'd seriously consider even if it meant selling them after the trip are the Canon 70-300 L IS or 300 f4 L IS or maybe the 400 f 5.6 L. Using a TC with the 300 might work but AF may be sluggish, &amp;amp; I wouldn't try it on either of the others unless you have very good manual focus skills. The 300 &amp;amp; 400 are relatively common on used equipment sites &amp;amp; if bought carefully could be sold for the same price after the trip.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

I can't use a heavy lens.&lt;/P&gt;&lt;HR /&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;It would depend on what you'd like to photograph.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;A couple of great lenses are &lt;A href="http://www.bhphotovideo.com/c/product/162616-USA/Canon_2577A002AA_100_400mm_f_4_5_5_6L_IS_USM.html/BI/5792/KBID/6654" target="_self"&gt;&lt;STRONG&gt;EF 100-400mm f/4.5-5.6L IS USM&lt;/STRONG&gt;&lt;/A&gt; and &lt;A href="http://www.bhphotovideo.com/c/product/680103-USA/Canon_2751B002_EF_70_200mm_f_2_8L_IS.html/BI/5792/KBID/6654" target="_self"&gt;&lt;STRONG&gt;EF 70-200mm 2.8L II USM&lt;/STRONG&gt;. &lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The first being more "flexible" in focal lengths but not so sharp nor "fast" as the second. Anyway it's a GREAT lens. If you want high quality image, you should consider using high quality lenses.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;With 5D Mark 3, the 70-200mm 2.8L II + &lt;A href="http://www.bhphotovideo.com/c/product/732111-USA/Canon_4410B002_Extender_EF_2X_III.html/BI/5792/KBID/6654" target="_self"&gt;&lt;STRONG&gt;2x EF Extender III&lt;/STRONG&gt;&lt;/A&gt; works really well regarding AF, but we didn't test it on the T5i. The AF performance may be very different.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I was thinking about going there too, but getting off the ship for sure &lt;span class="lia-unicode-emoji" title=":slightly_smiling_face:"&gt;🙂&lt;/span&gt; In my case I'd take wide angle and telephoto lenses for different subjects and topics (great landscapes, cientific bases, distant objects, animals, etc).&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Take care of the cold weather for you and your gear. Don't bring the gear into a warm room suddenly from cold outdoors without putting them into a zip lock bag or covering with a towel to &lt;STRONG&gt;let the gear get the indoor temperature gradually&lt;/STRONG&gt;. Otherwise your gear will get moisture condensation and it may get damaged easily, especially if the camera+lnes is not weather sealed. Some other people just leave the gear inside the bag/backpack for a while until it gets warm.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Keep the spare batteries warm in your pockets, and take spare caps too, you never know when you'll need some.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Regards&lt;/P&gt;</description>
