As I promised earlier, here are the photos. I got the Case Logic KSB 102 (price was a little less than Kata). I have only crop sensor cameras (40D and 50D) and the largest (or longest) lens that I have is Tamron 70-300 VC USD. The other lens is Tokina 12-24 DX f/4. As you can see the bag accommodate both pretty nicely. In the photos you can see that I kept one of the cameras with the 70-300 VC USD in the lower part of the bag (I can access this camera from the side of the bad through a zippered opening) and the other camera with the Tokina lens in the top chamber of the bag (with lots and lots of room to spare). Although I did not photograph, but I can confirm that the top chamber can easily accommodate the camera+Tamron combination as well. The lower chamber along with the camera can accommodate one or two flashes and one or two more lenses. The bag is pretty deep so any of these extra lenses can be as long as the Tamron 70-300. Most of all, now I can access one camera independent of the other. Both have their separate exit doors in the bag (that was my main issue).

PS: I could not follow any of the other fantastic bags suggested by you guys (for the time being) mainly because of the budgetary constraints. In future when this bag dies I will probably get one of those more strongly built alternatives (not that this one is not strongly built).

How can a "review" be accurate without being firsthand? Otherwise it will be "true" he-said-they-said..... may be true but not "review"....

EOS Bodies - For Stills / Re: Move to full frame (6D) or New Lens?
« on: July 16, 2013, 01:39:02 AM »
From the last paragraph of your post it looks like you are aware that you would not be able to use 15-85 on your full frame and still leaning (or heart is aching) towards a full frame.

I see many possibilities
1. 6D plus 24mm prime now and later get 24-70 f/2.8 (and keep your lenses other than 15-85mm)
  If budget permits I would probably go for a 35mm rather than 24mm, but all depends on budget.
2. Keep 7D, get 17-55 f/2.8 (in any case f/2.8 on crop is not the same as f/2.8 on full frame)
3. Keep 7D, keep 15-85 for all around and get the new sigma 18-35 f/1.8 for low light occasions.

Dear OP,

I hope you can see what can of worm you have opened by asking whether you should move to Nikon (whatever the pronunciation is) from Canon in a Canon forum. Neither I have that much knowledge about sensor technologies (sensor printing, what nanometer technology etc) nor I have any insider knowledge about what Canon plans to do tomorrow (or the day after or one month from now or one year from now or so on). However, assuming that opening the aforementioned can of worm was not your sole intention, I would beg to see some of your work where you think the current sensor technology of Canon has limited your creativity and where Nikon sensor technology would not. The pertinent point is I (or may I say we the CRians) would probably like to see the same photograph taken with your current Canon gear (which I do not know yet) and also with the Nikon gear you plan to buy (you can probably rent it). I shall be highly obliged if you do not resort to saying that "I have read Nikon can do better" after showing us a photograph taken by your Canon gear alone.

Thank you.

The Kata 3in1 also looks promising. So let me do some more search. Thank you again to all of you (and those who might chime in after this post).
Update if you get one of the Kata 3n1s (or an alternative). Still thinking about one, my backpack-style and sling are good but I am still looking for one pack to rule them all!

I surely will... In fact whatever I get finally I will update with photos (how I am fitting my gear). Thanks for all the suggestions and helps.

Hey guys thank you all for the suggestions and insights. All of you suggested very good quality bags, but may be I was unable to communicate myself fully to some of you (but I am still thankful for all the suggestions). For example I am/was not looking for something like Tamrac expedition 6x - which looks like a very nice sturdy backpack. But I already have one like that to "carry" my gear from one place to another and this type of "open me entirely to access the camera kept at bottom" is exactly what I am running away from. I am looking for a bag which can accommodate just two bodies with two lenses attached to them when I am walking around - on street roads, on the beach, in the forest etc (and only as much extra space for extra cards, battery, filters, and a remote trigger). Just that. When I am outside I rarely use flashes, and I hate to change lenses outside - so I do not carry extra lenses while actually photographing - those stays in my room (hotel or otherwise). And the two bodies are both crop bodies (40D and 50D). I somehow feel uncomfortable with the side bags - not sure why, but I feel restricted somehow in my walking. As some of you mentioned there is no bag that will meet my needs 100%. I need to do a bit of search on the suggestions of buying a trekking backpack and fitting it with padding and separators. I never thought about that. The Kata 3in1 also looks promising. So let me do some more search. Thank you again to all of you (and those who might chime in after this post).

I have been using a case logic camera backpack for two years now. It can hold my cameras and lenses well, but after repeated use I have found out one sever limitation of this (or this "type of backpacks"). So I am looking for something "different".

Ok, so what is the limitation? To be specific I use the Case Logic DCB-309 model which can be seen here
http://www.amazon.com/Case-Logic-DCB-309-Camera-Backpack/dp/B004JMZPK0/ref=sr_1_6?ie=UTF8&qid=1373265907&sr=8-6&keywords=case+logic+camera+backpack. Now this bag can carry all my gear when I am going from one place to another in car, or aeroplane or some vehicle. The problem is when I am walking around. But its entire frontal wall/side comes off (except the bottom hinge part) when the zipper is opened to access the camera. So If I am carrying two cameras one at the top end of the bag and another at the bottom then to access the camera that is at the bottom I have to open the entire bag. This creates lots of problems for me. And I do not like it.

Therefore I am looking for something like a lowepro Fastpack or case logic kilowatt ksb 102 (see here http://www.amazon.com/Case-Logic-Kilowatt-KSB-102-Backpack/dp/B009M3UULK/ref=sr_1_4?ie=UTF8&qid=1373265542&sr=8-4&keywords=pro+dslr+back+pack). Now each of these bags (and may be some others) has a side opening system. I can keep a camera at the bottom of the bag and take it out sideways. So far so good. But my issue I want to carry a second camera in the same bag - in the top compartment which opens from top and front without opening the bottom compartment. My question is have any of you used these back packs in this particular way? Can the top compartment hold a second camera body - of course not with a tele lens but may be with a wide angle or walkaround zoom (say canon 17-55)? The reviews on amazon does not specificially address this issue. Otherwise do any of you know/have used any other bag with this particular facility - one side open compartment at the bottom, and one top/fron open compartment at the top - for two cameras?

Thank you for your time and patience - the post became too long.

I did it daily...for many years.  I still do it, once in a while...I've got a microscope in my office, and 6 of them in my labs (all Zeiss). 

What sort of subjects, what sort of microscope, and is your plan to use a Canon camera adapted to a scope, or something else?

Thank you Neuro for your reply. I do not have answer to most of your questions, except one - I will probably use either a 40D or 50D adapted to the scope. I tried to search the net but could not find much in the blog world. So I am tried to get hold of a couple of books on the topic. If you have any online source from which I can learn about the scope of photomicrography that would be great. Thanks again.

For example my questions are of this sort, will a 40X-2000X be sufficient (and what can I photograph with each magnification level), should I go for brightfield or darkfield microscope, what type of objective should I choose etc. (I am specifically thinking about optical compound trinocular microscopes)

I am trying to learn a bit about Microscope Photography/Photomicrography (or whatever it is called). Any one here done this type of photography? Any guidance/direction will be appreciated. Thank you.

I just think of the bottom line: I really like these images, and see what is possible with this lens in the right hands. :)

That is a gem! I believe that is the most important criterion as well. Well said.

I think that's because it's not an overly popular lens. It's not very high quality anyways but it's rather cheap. I have one myself and i only use it rarely when i go to the zoo..but how often can you visit the same place :)
It works well for the price..don't expect L lens standard. great for people who don't use telephoto lenses very often and don't want to spend too much on an L.
Anyways, speaking of zoo photos, all these photos are taken with this lens.

May be true that it is not an overly popular lens. However it is debatable whether it is high quality or not - it all depends on what is "high quality". If only canon L lenses (and I am not even addressing the wide divergence of quality among the L lenses) are considered high quality or even the only acceptable quality then probably 50% of the photographers will have to work with "low quality" or "unacceptable" quality (by that definition).

Moreover who would really expect 70-300 L's quality from a lens that costs around $1000 less then? Is there any sane person who really does that (barring those who are already using the very recent offerings from Sigma)? 

Nice zoo shots by the way.

In the lens gallery I did not see any specific thread for this lens, so just creating a new one.
