I have question for the members of the forum. I have a Canon EOS 66 SLR. I have recently bought a Canon EOS 600 eith a Tamron 18- 270 lens.

Is it ok to use this lens with the older film based SLR camera.

Usually it is the other way round, people use old lenses with newer bodies. As long as the mounts match, there shouldn't be any issue in using the newer lens with the older body.

My first outing with the cheapest extension tube in the world went horribly wrong. I dont think I will be able to get any decent images with this set up. Today I tried it only with the 70-200 lens, it might be better with the 50mm which has aperture rings. There are many things one should know about an extension tube which has no electronic pins in it. I will give a detailed post next week ! Here is the set up used today.

hmm..so no aperture changes with that set up I guess
With 50mm it will be a bit easier..aperture ring and lesser weight.

Folks,

A basic question on photography and train travel.
How safe it is to carry a DSLR on a train (assuming AC coach).

The concern is higher if you are a solo traveller.

Any thoughts on systematic pre-cautions apart from being paranoid
about one's gear?

Risk is similar to your carrying a laptop with you in the train. its usually safe if you don't show off the camera inside train while traveling.

You could relax if its in an AC coach. I would not to take out the DSLR in a solo journey until I am in a comfortable company with my co passenger whom I can trust and one whose destination is same as mine or after mine. In my last two trips, I had seen co passengers keeping their iPad or laptop ON and visiting the loo with a comfortable trust that is build up among the co travelers.

Yes, I will try to be as clear as possible from my experiment. Please note this is my comments about an extension tube without electronic pins.

1) View finder is pitch dark through the tubes even on a full frame (FX) so I can imagine how tough it would be on a DX body.

2) Point one leads to the usage of 'Live view' which is unavoidable.

3) Point 2 leads to a very sturdy tripod. Hand holding ? Dont even think about it.

4) None of the G lenses and most of the third party lenses do not have aperture ring, which makes aperture control out of question. There might be some tactics but I could not figure out anything.

5) Quality is not supposed to be bad, but I did not find it anything exciting.

6) Mounts are not tight, 70-200 kept wobbling in between.

7) Exif data will show aperture as "0"

I am not in a hurry to throw this out of my bag, will have bit more patience and see if I can find something worth. Also need to try it on 50mm 1.4 which has aperture ring, but I am sure shooting bugs or flies will be out of question as the working distance will be hardly 3 or 4 inches.

I searched for days until I found a Samsonite bad that fits my laptop AND my DSLR bag together. Individually, the free bags that came with both screamed "Laptop" and "DSLR". Even if the robber guesses what they are, I have one less bag to bother about and I can carry it to the toilet on my back.

If you carry your bag to the toilet every time, that's an open announcement to every one on the train that you are carrying something very expensive.

True. But I'd rather do that while I am travelling alone on the train (which I do, mostly) rather than leave it at the mercy of unknown co-passengers.

Found this article related to AF lenses and extension tubes:

Macro Photography with Affordable Extension Tubes & Reverse Mount Adapters

The following steps to be followed to set the aperture.

1. Mount the lens as you normally would.
2. Set your aperture using your camera’s aperture adjustment knob/button to a small enough aperture. F/8 would be a good start.
3. Press the depth-of-field preview button of your camera, it’s usually located near the lens release button on your camera’s body. You’ll hear the aperture blades close and if you peer into your lens, you’ll see the blades of the lens.
4. Without releasing the DOF preview button, remove the lens from the body. Doing so will keep the lens stopped down.
5. Mount the lens to your adapter and you’re good to go

Unsure whether this will work in your case. The question is how the DOF preview button will keep the lens stopped down? Even if it works, still a tedious task IMO.

For bugs, you will be better off finding an old MF lens(>100mm) with good glass and an aperture ring. Given the weight of 70-200, I would not risk it with the extension tube.

Another possible option is to buy a cheap 2x TC with metal contacts (strong enough to bear the weight). Remove the glass and use it as extension tube

Now that you mention, one can buy a simple camera cover, push it inside a suit case.
The only problem is the need to take care, that no one tramples it.

Backpacks are available like Lowepro that fit both camera and laptop. But in a train journey, you will also have at least one more
carry bag, as clothes for long distance train travel, wont fit in the camera back pack. So the problem already gets compounded.

I guess the only solution if possible is to push it inside a strong suitcase and see that its not getting trampled.

Someone had suggested me the same and confirmed it worked on Canons, but I have not checked it with Nikon and would not try that by any chance. Somehow my 70-200 is mostly at f/8 or around that by default when its not in use (assuming by the gap). So, aperture was never a worry in the experiment. Test shots also confirmed more area was in focus.

Alternative option what you suggested is converter used as tube with the glasses removed, I have a 2X converter that costed around 9.5k and can not imagine to break its glasses A better choice is to get the Kenko tube set that comes with the metal pins. Anyway, my mind is on the Sigma 150 2.8 macro, no plans to buy anything for sometime, as there is so much to experiment with whatever is already in the bag !!

I've stopped traveling by train if it's a long journey (say more than 1 day). And if I have to travel by train (1 or 1 and half day) then I always keep my Camera bag with me, come whatever it may. Normally in a AC coach you are pretty safe but still I won't take a chance with my photography equipments while on train. If possible get a upper berth and get chains to lock your bag and locks for zips too and lock the bag on top corner of the berth. It might not be needed most of the time if you are in a AC coach. Best possible way is to never loose the sight of the camera bag.

Congrats ! Pentax is rare, I looked out for Pentax , found no B&M representation worth the name and knew it had to be Canon/Nikon. How did you procure yours , ordering online , B&H/Adorama/Ebay/Amazon ?

One significant downside to Pentax aside from the lack of manufacturer support is there is no FX body in the Pentax line up. No upgrade path from APS-C. Sure, there is the medium format 645D , yours for only $9999 !

Do you intend to 'test' its weather sealing properties ? the weather is just right !


OT : Enjoy some distraction from the Canon vs Nikon brand wars :-
