Lenses / Re: Selling my two Zeiss lenses. Your advice?
« on: July 27, 2014, 05:11:34 AM »
Zeiss lenses are typical Veblen goods The higher the price, the more difficult they are to use, and in general the more esoteric they are, the more some people will love them.

I don't think the OP is lying. Also the sellers do sell iPad cases and so I don't think someone switched - simply, the wrong order was sent and the OP screwed up because of the delays and the seller behaved badly. Maybe someone somewhere ordered iPad cases and got a 6D + 24-105 and decided to keep it. But, not a scam.

I just checked on eBay Beststopdeals. They have sold 63070 items with a 98.6% satisfaction rating. It's not stellar, but that is not feedback indicating scammers. I also looked at the two links given by Mt Spokane for CPW. They are not on the "bait and switch list", so I don't know why it was given, and the other link is a notification that beststopdeals will replace free of charge a 60D + 24-105 deal. Again, that is not scamming indictment.
Before you accuse a seller of doing a scam, present some better facts. It looks more like a delivery mistake plus poor service than a scam.

Lenses / Re: Going native at 400mm

I've heard good reports of the 400 DO in practical use - as opposed to the reviews......
I would check that out, too, though I can say that the 400 f/5.6 is a great lens if you can get used to the lack of IS.  Many of my best photos were taken during the 4 years I owned this lens.  The 300 f/2.8 II IS + 1.4x III and 2xIII is what I upgraded to and other than the cost, size, and weight, I can recommend it without reservation. 

Also, your post scared me a bit as "going native" means going without clothes in American slang :o

I have gone through the 400mm L, a great little lens, the 100-400lL, a very useful lens, the 300/2.8 II plus extenders, the Tamron 150-600mm and a Sigma 400 tele macro. The 300/2.8 II is my go to lens followed by the Tammy. The 300 with extenders is so user friendly and sharp and contrasty.  However, I think the Tammy is at least as good as the 100-400 where it overlaps and the 600 is quite good. So, take your choice as you should be happy with both.

Because, there are survey results 4-5% of customers who bought the kit lens is that it does not use only kit lens.

Would indeed be interesting to see an accurate translation of this. Do 5% never buy another lens? If so that is an amazing stst

I could believe that easily 4-5% never buy another lens.  I know people with DSLRs that bought a kit and are just fine with their kit zoom.  They take pictures only once in a while such as on a trip or at some big event.  It just depends on how much they get into photography.

I sincerely doubt it means 4-5% don't buy lens(es) beyond the kit.  The lens + body sales milestones (100M lenses, 70M bodies) aren't consistent with that interpretation.

Perhaps, you have bought 30M lenses so the rest of the world has only one per camera. Or, perhaps 5% of 70M (3.5 M) have 30M lenses, ~9 per camera, whereas the remaining 95% have only one each.

I would like an umbrella head for wet weather. Perhaps Surapon could design one?

Reviews / Re: Review - Sigma 35mm f/1.4 DG HSM
« on: July 21, 2014, 10:15:30 AM »
The Sigma 35 is indeed very sharp. However, I tested it carefully against my old Canon 24-105 L at 35mm, using an iso 12233 chart. The 24-105 is sharper (at f/4 on both)! This is the second time the old workhorse has outshone the new pretenders (last time a Tamron 24-70 VC).

The Sigma 35 A is reported by Photozone and lenstip as having significantly superior MTFs to the 24-105. Either I have been unlucky with the Sigma and Tamron and getting poor copies or I have been very lucky and have a 24-105 which is an outlier in the right direction.

Lenses / Re: Safari 300 2.8 Mkii or 200-400 1.4x
« on: July 19, 2014, 05:07:13 AM »
Living in Botswana, let put across my experience. I used to use the 300 F2.8mk1 with a1.4X TC permanently fitted on my 7D. I was quite happy with the combo and as I was still learning to use my gear I did miss a few shots here and there. Last year during some major upgrades, I sold off the 300Mk1 and replaced it with the 200-400mm . My reasons
1) Versatility of the zoom for composition cannot be beaten !!!
2) I dont have to worry about weights and losing luggage enroute to places. I usually book a private safari and pay through my nose for having certain privileges such as being the only person with the guide on the "Bakkie"/ Open Safari vehicle.
3) The higher F stop is not too much of a problem for me.
4) Dust is a B***H, it gets in everywhere.
5) I usually holiday in private concession which means that we can go off road , where as in the parks you are restricted to the roads and will need a longer lens.
6) After two holidays with the 200-400, I am very happy and impressed with having it on a 1Dx !

PS: I am thinking of adding a 600mm with a crop body( 7D2?) and 1.4X TC for Birding ! :P

Does your manservant carry your gear for you?

Lenses / Re: Safari 300 2.8 Mkii or 200-400 1.4x

We were in SA on safari, together with my wife. we had a 300f2.8ISi and 70-200f4IS and a 2xiii Extender on 5dii and 50d

in "good light mode" we had the 300mm on the 50d normally with extender, in the evening, we removed first the extender, next changed the 300mm on the 5dii and maybe the 50d to a fast 50mm.

this, because:

- a crop camera is the better extender than a real extender
- the big whites are so bitingly sharp, that their resolution is enough for the spaller pixels on the crop sensor
- with 2 cams one gets different perspectives at the same time.

For the (in my opinion) way overpriced 200-400 you can probably take a 2nd person on the trip, who does the 2nd perspective (and helps to carry all the stuff).

If money doesnt matter, and if y can carry the weight of the 200-400, i would take a 400f2.8 instead, with the same strategy, and would use a 1 crop and one FF camera instead of 2FF

+1 for much of this. For animals, I found the 7D with 70-200 more than adequate, but too short for birds. What I would do next time is take the 70D with the 300 f/2.8II + extenders and, in my case, the Tamron 150-600 on the 5DIII (or 1DX if I had one) to be ready for all events. You really do need a zoom. The Tamron is more than adequate for animals during the day time. At dawn and dusk I would put the 300mm on the 5DIII.

My Sigma 35L arrived on Monday. On FoCal testing, the AFMA on the 5DIII was +4 and on 70D -2. The focus consistency on both bodies is the best ever I have ever encountered: 99.2% consistency of focus on both bodies and incredibly sharp. The lens is very well built and fits very precisely with no play on to the body.

The TDP tests above are done on full frame sensors. It is a different story on crop, which shows up the deficiencies on the less-than-tack-sharp lenses. On the 60D, for example, there is clear daylight between the 400 mm f/5.6  L at f/5.6 and the 400 mm  f/2.8 L II at f/5.6.

and also the 300 mm f/2.8 II at 420mm with a 1.4xTC at f/5.6 has similar superiority:

It's not just the TDP site that shows this and it is confined to the 60D, but also DxOmark in its tests on a variety of bodies, and as found by me in my use of the 100-400, 150-600 and 300/2.8 on the 5DIII, 7D and 70D.

Whether you prefer the Tamron to the 100-400 or vice versa is your decision, but I sold my 100-400 for the 150-600mm and am very happy with it on FF. I wouldn't recommend either on a crop body for the highest quality images, but they are both more than adequate for more general use.

(The DxO tests are done on the 100-400, not the 400 prime, but they are consistent with TDP)

To put it into perspective, there is not much difference between the 400/5.6 L at f/5.6 and the Tamron 150-600mm at 400mm f/5.6.

The 35mm A arrived today. It required only +4 AFMA on the 5DIII and -2 on the 70D, by FoCal. The consistency of focus on both is 99.2%, which is better than any of my other lenses. It has a nice balance on the camera, has a an exactly fitting bayonet mount, and feels very well made. The first shots are very sharp. Downloaded the DxO module and it removed the vignetting at f/1.4 nicely. So far so good.

Rotating zoom ring

Bummer.  :(

You'd prefer one that wouldn't rotate?   :P

Despite the controversy, I rather like my push pull 100-400.  Never had a dust problem...  I would welcome faster AF.  That's the only downside I have experienced with mine.  I would be (pleasantly) surprised if the price is $2400.

I agree - push pull is a very robust design and it is a retrograde step to give us a telephoto like the 70-300L although admittedly that is a good lens optically but is not as tough as the current 100-400 where the front optical assembly slides along a rigid tube.

I'm with you guys. The small size of a push-pull makes a great compact unit. It will have to outperform the Tamron 150-600.  If it does, I'll buy.

Insurance is a casino game between you and the insurance company in which the odds are stacked in their favour. Many years ago, I was given the advice that you insure yourself only against events that happen very rarely and are too expensive for you to cover. If you can afford to replace your gear, then don't insure it because the insurance companies have the odds stacked in their favour - they make a profit because on average the insurance premiums cost more than the cost of repairs and losses.

So I take it that you don't insure your house or car either?  Of course insurance companies are out to make a profit, they can't provide that service for free!  The model is for them to spread the risk over many in hopes of reducing their risks and keeping the premiums lower for everyone in the group.  That's just how it works.

You clearly haven't read what I wrote and you don't understand odds.  I insure my house because I could not afford to replace it if it burned down. I don't insure my washing machine because I can afford to replace it if it breaks down.  I don't bother to insure most of my photographic gear because I am more careful than the average bear and rarely drop or lose items or leave them where they can be stolen and I can afford to replace them. If I insured them I would be paying over the odds to have the insurance company make a profit and to pay for all those careless individuals who don't look after their gear.
